Rebuilding the Atari 5200 CX52 Joystick.
Based on Rebuilding Thousands and Thousands of Atari CX52 Joysticks over the last 20+ years and Selling the Atari OEM 5200 replacement Joystick parts to 20 to 30 thousand Atari 5200 Joystick end users and rebuilders, we have developed a extensive Knowledge base on the proper rebuilding of Atari CX52 Joysticks. Best Electronics is the Only Atari company on the Internet to provide you with such an extensive and informative article on rebuilding Atari CX52 Joysticks.
To show you how State of the Art or ahead of its time Atari Engineering’s design of the CX52 Joystick was for its day, some 15 to 20 years down line, most of the current PS2, Nintendo, Sega and Most PC Joysticks use the same type of internal designs pioneered by Atari Engineering on the CX52 Joysticks. Flexible Circuits, Silicone pads with Carbon Dot contacts and Analog Potentiometers (Pots) for X Y Movement (PC Joysticks) are now industry standard type of construction today.
The Basic construction of the Atari CX52 Joystick housings are so well designed, that in most cases you can just about rebuild them for just about ever. All Joysticks are like Tires on a Car. They have parts that wear out! You do not expect your New Tires on your car to last a lifetime, no matter how little or much you spend on them, the same goes for any joystick. The more and harder you use them, the sooner you will have to replace or rebuild them.
Q. How difficult is it to rebuild an Atari CX52 Joystick and should I attempt to rebuild them or Send them into Best Electronics for exchange on some Freshly rebuilt Atari CX52 joysticks?
A. To properly rebuild an Atari CX52 Joystick, will require a person with some Mechanical knowledge. It is a little harder than changing a Tire or Battery on a car but not as bad as doing a full tune up.

All Best Electronics freshly Reconditioned / Upgraded Atari CX52 Joysticks come with a 90 day Warranty (same as when sold new) and are supplied with the Unique and Exclusive Best Information sheet, How to extend the Life of your Rebuilt Atari CX52 Joysticks!
Q. We just dug out our old 5200 system. The Atari CX52 controllers look brand new but do not seem to work?
A. Yes this is one of the standard symptoms of Very Old (6 - 20 years old) but new looking Atari CX52 controllers. The Left and Right fire buttons or the Start, Pause and Reset buttons do not work properly.
Q. I saw on eBay somebody listed New in the box Atari CX52 controllers for sale. Would you recommend I buy them?
A. No, Atari has not sold any new CX52 controllers for about 9 – 12 years now. The last brand new Atari controllers Best bought wholesale out of the local Sunnyvale warehouse about 9 – 12 years ago, had about a 25% to 45% failure rate right out of the New box. By today’s date they should now have about a 60% to 90% failure rate New in the box. I think they had been sitting in the Sunnyvale warehouse for about 4 – 5 years earlier and just went bad. Freshly rebuilt Atari CX52 Joysticks with new replacement parts will give you the maximum CX52 controller life today.
Q. What basic tools will I need?
A. Philip’s Screwdriver, Flashlight, a small straight blade screwdriver, 5200 Missile Command Game Cartridge and about half hour to 45 minutes time the first time thru. Optional new Dust / Powder free disposable thin rubber gloves.
Q. Do you have 5200 parts Kits to rebuild Atari CX52 Joysticks?
A. No, everybody seems to order different components to rebuild their Used
Atari CX52 Joysticks depending on their exact condition. But we do have a Recommended Minimum set of components based on the 20 years we have been rebuilding Atari CX52 Joysticks, to get the Maximum life out of your CX52 Joystick rebuilt controllers. You should 100% replace the Flex Circuit, both left and right Fire Buttons and the Auxiliary pad (Start, Pause, and Reset) on each CX52 controller you are rebuilding. Basically you are replacing both sides of a mechanical switch. Like when you do a tune up on car, you do not just replace the distributor cap because is looks bad and reuse the rotor because it looks good, you replace them in matched sets for maximum tune up life. Many Atari CX52 Joystick rebuilders on the Internet or eBay, mix old used Atari CX52 joystick parts with new ones (they order mismatched sets of CX52 replacement parts from us). These rebuilt Atari CX52 Joysticks seem to work perfectly fine when you receive them. But in long-term use they will fail a lot sooner because of the mix of used and new parts.
From there you might need, Numeric keypads, Rubber boots, Controller cables, Pots, missing or damaged 52 Joysticks plastic parts. See the extensive Atari CX52 Joystick parts listing we have in stock at the end of the article.
Disassembly of the Atari CX52 Joystick
If you have several Atari CX52 Joysticks you are rebuilding for the first time, it is Recommended to do one at a time. That way if you forget how the fully assembled Atari CX52 Joystick looks like (or you run into a reassembly problem) when you are rebuilding your 1st CX52 joystick you will have a master(s) to go back and compare to. There is nothing more frustrating than taking apart several CX52 Joysticks the first time and forget how to put them back together again.
Turn the CX52 Joystick over, remove the 3 Phillips screws from the backside of the CX52 Joystick. Start at the top were the controller cable goes into the CX52 Joystick. Grab the top and bottom (12 ‘O clock location) and case halves of the CX52 joystick case. Put your fingertips / nails in between the case halves and pry them apart just a little (1/16 to 1/8 of an inch) but no more at first. Now move down to the bottom half (6 PM) of the Atari CX52 controller case, by the bottom of the numeric (phone) keypad. Pry this end of the case halves open the same amount as the top case. Now go back and forth between the top and bottom ends of the controller and slowly open it up.
The reason why you open up the Atari CX52 controllers halves this method is, on the numeric end of the Atari CX52 controller, inside of the top and bottom cases are a couple of locating plastic Male pins (top controller half) and mating hollow studs (bottom case). If you open up the top half (by the controller cable end) at to much of an angle, you can snap off (break) these internal aligning pins on the inside of the top controller half by the bottom inside edge by the numeric keypad.
Best Atari Tech Tip: prying with any type of tools (like a straight blade screwdrivers) along the sides of the CX52 controller halves to help pry the case halves apart, will leave dings in the top and bottom cases side halves edges, that you will feel with your palm of your hand and fingers when you are using the rebuilt CX52 Joystick. So it is best to use NO tools to pry the case halves apart.
As you slowly pry the controller halves apart, look from the left topside of the controller splitting case halves. Toward the top of the CX52 case (directly behind the left fire button), just inside of the top and bottom CX52 case halves, you will see the thin 3/8 to ½ inch wide flex circuit strip (Green, White, Blue in color) pull out of the top half of the CX52 joystick. This is normal! Instead of wires, this flexible flat strip is half of the mechanical Switch in the Start, Pause, and Reset circuit.
As you split the CX52 case halves and remove the CX52 top assembly, you will see the Left and Right Orange Fire Buttons in their slide in bezels (holders), numeric 1 – 9 silicone pad, and the Flex circuit. On the bottom half of the CX52 case, look for the two X Y controller Potentiometers (Pots) (Sliver, Brown or Black in color, about 1 inch wide diameter) (top 1/3 half of bottom case) with a small white pot arm pressed onto each of the ¼ round shafts.
Now turn over the top CX52 controller top. On the inside of the top CX52 assembly, look were the white shaft that comes thru controller top and fits into two sliding plates (top and bottom Actuator plates, black or white in color).
Note: the end of this White pivot shaft fits into a cup shaped holder on the bottom of the CX52 Joystick case between the Top and Bottom pots.
These two sliding plates in the Top CX52 case halves fit into two X Y different slots in the case half. When you reassemble the rebuilt CX52 Joystick, both siding plates must sit in these two slots / channels flat and slide freely left to right and top to bottom. You may or may not have to play with these plate assemblies (X2) so they sit flat into the top controller during reassemble.
Best Tech Tip: During reassembly of the Atari CX52 Controller halves, Hold the controller handle on the top CX52 case half in Top Dead Center location when installing it on the bottom half of the CX52 Controller. Also apply a little pulling (upward) pressure on the handle to hold the two Internal Actuator plates flat in their slots (on the inside of the case half) during assembly.
On the outside of the top half of the CX52 controller assembly, the Auxiliary silicone pad (Star, Pause, and Reset) is held into the top case half with a snap in / lock in rectangular plastic bezel. There are two basic styles of this snap in bezel, one with rounded edges and one with angular edges, which are interchangeable.
To remove this snap in Auxiliary bezel and remove the Auxiliary silicone pad from the CX52 top assembly, turn over the CX52 top half controller. Using a flash light, look on the inside of the top assembly under the Auxiliary pad area. On the far right and left hand sides of Auxiliary pad area (inside the controller top cavity) you will see a little rectangular shaped depressions on each end. Insert a small flat blade screwdriver into one of these rectangular cavities on the inside of the CX52 Controller assembly. Slightly twist your small straight blade screwdriver clock wise or counter clock wise. This will unlock the little locking clip on the snap in Auxiliary brown bezel and it should fall off the CX52 top assembly with the Auxiliary silicone pad.
Safety Note: When removing the Auxiliary bezel assembly, do not hold the top assembly with the palm of your hand directly under the Auxiliary Bezel area. Hold the top assembly slightly down from this area. Sometimes it takes some twisting downward pressure on the straight blade screwdriver to remove the snap in Auxiliary bezel from the top CX52 assembly. Many times over the years we have stabbed ourselves in the palm of our hand with the screwdriver blade as the snap in bezel finally came out of the CX52 Top assembly and the screwdriver blade passed from the inside of the top case to the outside of the case, thru the Flex Circuit pass thru rectangular opening / hole on the inside left or right hand side of the controller top.
On the bottom half of the CX52 controller half, remove the left and right CX52 fire buttons with their brown plastic bezels (both fire button bezels are interchangeable) and numeric keypad. Under each left and right fire button you will see the flex circuit strips, which are held into the CX52 controller with double sided tape. Slowly pull each fire button flex circuit strip off the right and left sides on the bottom controller half. Do not use any tools (like a straight blade screwdriver) to remove the fire button flex strips because you may scratch or damage the plastic mounting surface under the fire buttons. Note as you are removing the left and right flex circuits under the fire buttons, look for a small aliening notch on the bottom of each fire button flex circuit strip that Must fit into a small aliening / mating plastic tab on the inside of the CX52 bottom case half (use your flashlight to see these small aliening plastic tabs inside the bottom case assembly) when you are installing a new replacement Rev. 9 Flex circuit.
There should be enough double sided adhesive left over from the old flex circuits on the fire button left and right plastic backing plates, that will not need to replace this tape during the reassembly process.
Now move down to the numeric pad area on the flex circuit. This numeric portion of the flex circuit is held down on the removable numeric plastic support plate with a strip of double side tape, near the white cable connector.
Very carefully grab this flex circuit support plate on the left and right hand sides with your finger tips (under the right and left sides) With the same technique as opening the CX52 case halves, slowly lift the flex circuit support plate starting from one side just a little and then lift the opposite side. Go back left and right until the flex circuit comes off the bottom CX52 case.
There are three male plastic aligning pins molded into bottom of the numeric keypad support plate and female receptacles on the bottom half of the CX52 bottom case. If you pull this support plate off at too steep of an angle from one side or the other, you will break off one of the three aligning pins on the flex circuit support plate.
If you have a very stubborn Flex Circuit support plate
that is pressed / locked into the bottom half of the CX52 controller half, you
can break it free by gently prying the bottom of the Flex circuit support plate
using your straight blade screwdriver. But try not to ding or damage the bottom
edge of the CX52 case half with the screwdriver shaft.
As you slowly remove / pry the Flex circuit and Flex Circuit support plate assembly (together) from the bottom half of the CX52, note how portion of the flex circuit comes out of the long white horizontal female connector at the top of the Numeric keypad area. Also note, just about as the Flex circuit assembly is finally about ready to come of the bottom CX52 case, that there is flex Circuit loop (Upside down U shaped) portion that is installed under the numeric support plate during reinstallation of a new Rev. 9 Flex circuit.
Now that you have the Flex circuit and Flex circuit support plate out of the bottom half of the CX52 case, remove the old Flex circuit off the support plate. As you are removing the old flex circuit off the support plate, note there are two aligning tits (very small studs) on the surface of the support plate that fit into aligning holes on the flex circuit during reassembly.
This is a Very rare prototype Atari CX52 Joystick Flex Circuit. It uses the same type of Crinkle dome contact switches as used on the original Atari CX40 Joystick internal PCB board. Unfortunately this prototype sample Flex circuit does not work properly, so it was never used on CX52 Joysticks. Very few Atari people outside of Atari Engineering have ever seen this Rare one of a kind Prototype Atari 5200 Flex Circuit.
Things to check before installing your New Atari CX52 OEM replacement parts
Each X Y pot (X2) on the CX52 joysticks are super glued to the bottom of the case. Many times, the Super Glue bond breaks over the years use and lets the Pot tip over at an angle during use thus causing a binding feeling during use. To make sure the glue bond is still good, grab the part arm and give it a gentle pull up. If the Pot comes out of its holder or tips over, it is time to reglue it back into place.
Note if you have to super glue (No other type of adhesive seems to work as well) in your pot(s) again, only apply the super glue to the outer circumferences of the bottom of the pot (avoid applying Super Glue to the center portion of the bottom of the pots), some CX52 pots have an exposed shaft thru the bottom of the pot. If you super glue this exposed center shaft portion of the pot to the CX52 bottom case, you will get some binding (drag) on that pot when you use your reassembled CX52 Joystick.
After you reglue the pot and reinstall it, apply a lot of pressure on the top of the Pot arm / shaft to make sure the Pot is fully seated on the bottom of the CX52 bottom case as the Super Glue cures. If the pot is not fully seated flat during the gluing process, the top of the pot arm(s) will bind / drag on the two upper sliding Actuator plates.
Double check all of the pot wire connections. Many times the pot wire Molex slide on contacts, short against each other (like when a pot looses it glue bond and tips over). If the Molex spring slide on contacts on the Pots(s), look close together push them slightly apart using your straight blade screwdriver. Check and make sure none of the internal pot wires and cable harness wires are rubbing against the pot arms or will be pinched (top screw hole) or will be crushed (Actuator Plates) when you close up the top and bottom case halves.
Installing New Atari CX52 Parts
The first time, you will need about 3 to 4 hands to properly install the flex circuit assembly in the bottom of the CX52 bottom controller. Install the New Rev. 9 flex circuit on the support plate using the two aligning studs on the support plate and flex circuit aligning holes.
Best Tech Tip: Avoid touching / putting hand oils, sweat on any of the exposed metal girds of the Flex Circuits. The same goes for any of the Black Carbon contacts or Gold contacts on any of the new Silicone replacement pads. You can use New Dust / Power free rubber gloves or paper towels to avoid coming in direct contact with any of the Flex Circuit or silicone pad switch contacts.
Now tuck the upper Flex circuit loop (upside “U” shaped portion of the flex circuit) (above the white connector finger contacts area on the flex circuit) under the flex circuit support plate. Then fold down the right and left side of the fire button flex circuits strips (so the will fit into the bottom half of the controller). Next hold this flex circuit and support plate assembly just over the bottom CX52 case and align the 3 support plate studs over the bottom CX52 housing support plates holes (3). As you slowly lower the flex circuit and support plate and tucked under Flex circuit loop into the bottom half of the CX52 case, insert the flex circuit edge card silver fingers into the white horizontal connector at the same time as you are pushing the support plate with the flex circuit into the bottom 3 aligning support plate holes. Make sure the flex circuit fingers (Mylar strip) is evenly inserted into the white horizontal pinch connector side to side. It is possible insert the flex circuit silver fingers so they do not make contact with the mating pinch connector metal contacts.
Once you get the flex circuit and flex circuit support plate fully seated into the bottom CX52 case, double check to make sure the edge card fingers of the flex circuit are fully seated into the white mating connector. Newly installed replacement flex circuits have to tendency to ride up (look from the left or right side of the bottom half of the CX52 assembly for a hump up in the flex circuit at the top of the support plate) on the support plate (that is why Atari put double sided tape at the top of the Flex Circuit support). If you see this flex circuit hump, push the flex circuit fingers fully into the white cable connector until this flex circuit hump disappears.
Next make sure the left and right fire button flex circuit ends are fully seated in place with the bottom of the fire button flex circuits in their small aligning notches.
With a clean paper towel, press each left and right fire button flex circuit strips against each right angle fire button support plate with the adhesive.
Next insert the new CX52 fire buttons into their fire button bezels (the fire buttons are symmetrical so there is not top or bottom ends or right or left sides) and then insert them into bottom half of the CX52 controller bottom. Get your flashlight and make sure the bottom edge of the fire buttons have not folded underneath themselves as you are inserting / sliding them into the bottom CX52 case.
Get the numeric silicone keypad. Note that on the CX52 numeric key pad that there are two small aligning thru holes between the 4 / 7 and 6 / 9 button portion of this pad. These two holes in this numeric silicone pad match up with the aligning studs on the support plate and holes in the flex circuit. Note the aligning studs on the flex circuit support plate are NOT tall enough to fit into the numeric silicone pad but are used as assembly reference points.
Drop the numeric silicone keypad on the Rev 9 flex circuit making sure you align the keypad 2 holes over the flex circuit support plate studs (which are now flush with the top of the flex circuit).
Now look into the bottom CX52 housing. Notice the two Pots with the white Pot arms on the shafts. Align the Top Pot arm so it points to 9 AM and the Bottom Pot arm so it points to 6 PM.
Next grab the CX52 Top assembly. Use above Best Tech Tip and hold the shaft assembly per instructions. Align the CX52 top assembly over the bottom case. Next grab the Auxiliary Keypad circuit strip section of the Rev. 9 Flex circuit (off the left fire button) and insert it into the inside of the CX52 top assembly rectangular pass thru opening, left side under the Auxiliary keypad area. Reach over the top left side of the CX52 assembly and pull the Rev. 9 Flex circuit Auxiliary Pad strip thru the left rectangular opening in the Auxiliary pad cavity. If all possible, again try not to touch the metal grids of the flex circuit with your fingers (thus leaving skin oils) during reassembly.
Now gently lower the CX52 top assembly on the bottom assembly. If the numeric keypad and Pot arms are in their proper locations and you held the shaft assembly per above Best Tech Tip instructions, the top assembly should drop on the bottom assembly close evenly around the case halves. It may take you 2 to 5 times of practice before the CX52 joystick cases will properly close up evenly.
If you have the CX52 Joystick cases half closed up properly, the Auxiliary Flex circuit strip should lay flat in the Auxiliary top cavity. If the right end of the Auxiliary Flex Circuit strip is over flowing the right hand side Auxiliary Cavity or does not meet flush with the Right hand side Auxiliary Cavity wall (when the Flex circuit strip is laid flat) then you have a top and bottoms case closure problem, or the left fire button flex Circuit is not fully seated in it aligning notch.
Next grab the CX52 Joystick handle and make sure if moves freely with No binding action. If it binds, disassemble the CX52 again and start over with the reassembly process. Binding is usually caused by the sliding actuator plates not flat in their proper slots, the pot arms are knocked out of their 9 and 6 O’clock positions during the reassemble process or some pinched wires.
Before you completely reassemble the CX52 Joystick, you should test it for proper operation.
Insert the CX52 joystick cable connector into the far left hand port on the 5200 console. Insert a Missile command cartridge into the 5200 console. Turn on the 5200 game. Hold the CX52 joystick handle in the top dead center of the CX52 joystick.
Using the small straight blade screw driver blade, and touch the far left Auxiliary flex circuit Top and Bottom interlocking “E” grids (Start switch) in Auxiliary keypad cavity. If everything on the inside of the 5200 controller is OK, the Missile Command cursor should start in the middle of the TV screen. Draw an Imaginary X on the TV screen from Upper left corner to bottom Right corner and Upper Right hand corner to bottom left any corner, to find this center / middle TV screen location.
Try moving the CX52 Joystick handle and make sure the Missile Command cursor moves freely around the TV screen. Try the left and right fire buttons.
If all seems OK, Stop the Game (touch the far right hand set of interlocking “E” grids in the Auxiliary cavity, (Reset switch) with the straight blade screwdriver). Next then turn over the CX52 Joystick and install the 3 screws into the bottom case.
Before you reinstall the 12 o’clock screw, use your flashlight and look into the screw cavity to see if you can see any pinched wire(s) between the top and bottom case halves.
Best Tech Tip: After you screw in the 3 CX52 controller case screws (using a Manual or power Phillips screwdriver) it is recommend that you back off each Phillips screw head a half to ¾ of a turn. There are two reasons why you should back off these CX52 case screws. On some Atari CX52 plastic Top case halves had under length threaded screw bosses (some CX52 top case plastic threaded screw bosses has a little round paper spacer placed on the end of the screw boss to add length to the bosses to fix this problem) when you tighten the 3 CX52 case screws completely down, you would cause the Top and Bottom internal CX52 Actuator Plates to bind and cause the CX52 Joystick handle to feel very stiff. The second reason to back off the screw heads, is when you have well worn Top and Bottom Actuator Plates with a lot of drag marks on them. If you back off on the screw heads you will find the CX52 Joystick handle will go from a Stiff feel to a little more smoother auction.
The last items to install in your CX52 rebuilt controller is, the Auxiliary keypad and Auxiliary snap in bezel. First hold down the Auxiliary flex circuit flat inside the auxiliary cavity (make sure you use the Paper towel trick and do not touch the Auxiliary flex circuit metal contacts). Next drop the Auxiliary silicone pad over the flex circuit. Before you snap in the Auxiliary locking bezel, make sure the Start button is on the left side and Reset button on the right side.
Note: We have not included in this article how to replace the rubber joystick boot on the Atari CX52 Joysticks. In a lot of cases it takes a special tool (pictured below) to properly remove the pressed on CX52 handle (required to replace the CX52 rubber boot). The pressed on CX52 handle can sometimes be removed without this tool, but it is a little harder job than the basic Skill level this article is written for. The CX52 joystick rubber boot is basically a cosmetic part and will not affect the overall performance of any rebuilt CX52 controller.
Trouble Shooting a freshly rebuilt CX52 Joystick.
Q. One rebuilt CX52 Joystick works perfectly and the other still has a (left or right fire button or numeric keypad problem.
A. Most likely the problem rebuilt CX52 Controller has a bad controller cable. But it can also be that the flex circuit fingers not fully seated into the white cable connector.
Q. On the 5200 Game Super Breakout the bottom cursor shakes as it moves side to side.
A. The bottom Pot inside the CX52 Joystick is bad. You can spray some Pot cleaning solutions inside the pots, but we find this is only a temporary fix. We find the Pot will again go bad soon. It is best to just replace the bad pot.
Q. On the 5200 Game Super Breakout, the Cursor will not go far left or right. (Or on Missile commend the cursor will not go all the way to the top or bottom of the screen.
A. Most likely the bottom pot arm has slipped on the pot shaft (in the Missile Command case, the Top pot arm has slipped) You will have to disassemble the rebuilt controller again. You can adjust the position of the press on pot arm on the shaft by turning the pot arm full clock wise or counter clockwise until it stops turning. Once the pot arm stops turning. Apply a little more twisting pressure on the pot arm until you feel it slip just a very little on the shaft. If you over correct the position of the pot arm on the pot shaft, you will have to turn the port arm the opposite direction until it stops and again apply pressure on the Pot arm until its slips just a little again. Note in some cases it will seem that the port arm is glued or molded on to the pot shaft, but it not, it is just a Very Very hard press fit. Once you have the correct the cursor position, it is recommended you apply pressure on the top of the pot arm to lock it back onto the pot shaft.
Another cause of this problem can also be an electronic problem (adjustment) on the 5200 motherboard. If both of your rebuilt CX52 joysticks have the exact same left or right / top to bottom cursor problems, then the problem is a 5200 electronic drift problem on your 15 to 20 year old 5200 console and NOT a slipping pot arm on the pot shaft. Call us for more information and how to correct this problem over the phone. Have your 5200 console set up on your TV ready to use, a rebuilt CX52 Joystick, Missile Command or Super Breakout 5200 Cartridge, a Phillips screwdriver and a small straight blade screwdriver.
Q. The fresh rebuilt CX52 Joysticks (even with the new Gold Dot Pads) seem to go bad fast (1 to 5 months) and have to rebuilt again.
A. Mostly likely you have a bad 15 to 20 year old 5200 Motherboard with weak joystick port circuits. We find in 100% of the cases, when we send out a replacement 5200 motherboard up to Factory specifications, rebuilt carbon dot CX52 Joysticks go from months of use, to the normal Years and Years use between rebuilds.
Q. I have the same problem(s) on both fresh rebuilt CX52Joysticks.
A. First try both rebuilt CX52 Joysticks on both ports 1 and 2 (two player 5200 Game cartridge) to see if the problem is in a particular Joystick port or a 5200 Motherboard problem. If you determine the problem is with one 5200 console joystick port, pull out the controller cable out of that port and make sure you can see 15 exposed Male pins on the 5200 console port. Some 5200 joystick problems are caused by a pushed in male pin(s) or broken pin(s) on the DB-15 Male 5200 right angle connector.
If the problem(s) are the same on both ports, then the 5200 Motherboard is most likely bad and will have to be replaced.
Q. As I play with my freshly rebuilt CX52 Joystick, some of the functions (like fire buttons) seem to work, then stop working and then start to work again. On 5200 Missile Command, the cursor jumps from middle of the screen to a bottom corner of the screen while I play the game.
A. Mostly 1 to 14 of the wires in your CX52 cable assembly are broken or shorting out within the cable housing (usually this happens near the CX52 Joystick cable strain relief next to the top of the CX52 Joystick controller case or by the CX52 joystick plug in cable connector strain relief next to the Atari 5200 console joystick port). As you flex the CX52 cable housing during play these bad wire(s) make and break contact or short out.
Q. Some of the Keypad number functions work and other are dead.
A. Disassemble the CX52 controller again and make sure the Flex circuit edge card silver fingers are fully seated into the White Molex pinch connector. If they are fully seated then you have a bad CX52 Controller cable. It can also be a bad new flex circuit, but this is extremely rare!
Q. The first time I resembled the rebuilt CX52 both Pots were working fine, but I had another problem and had to disassemble the CX52 again. Now one of the Pots is not working at all.
A. Disassemble the CX52 Controller again and look for damaged (cut or pinched) Pots wires (X4). Also look for Pot wire metal slide on contacts that have come off the Pot metal contacts or broken off pot metal contacts.
Q. One of the older (well used) rebuilt CX52 Joystick feels Stiff compared to the newer (less total use) rebuilt CX52 Controller.
A. Replace the worn Top and Bottom Actuator Plates and the Actuator Square slide block (in a matched set) on the stiff feeling rebuilt CX52 Joystick.
