bradhig1 Posted October 2, 2018 Share Posted October 2, 2018 I have an A/V modded atari 2600 jr that I was about to play a game I picked up at Vintage Stock today Space chase. When I picked up the joystick I think cable caught on another calble and I heard something pop inside the system and the picture went out. i looked inside it and the mod is fine and the power supply works on another atari. No pciture ,sound or power light. I took a photo of the inside of it.. Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted October 2, 2018 Author Share Posted October 2, 2018 Is there a fuse on it that might have blown? Quote Link to comment Share on other sites More sharing options...
Osgeld Posted October 2, 2018 Share Posted October 2, 2018 The video out wire is ultra close to touching ground on the board Otherwise when you turn it on does the power regulator warm up you might have popped the power jack loose from the board theres nothing holding it down but its pins and the plastic on those get brittle Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted October 2, 2018 Share Posted October 2, 2018 I'm with Osgeld here, it is most likely that the power connector has come loose from the main board. Since you have it open and apart, does the power jack move side to side or up and down? Also..what is that component at T1 located far right and center of that circuit area? It doesn't look good from the closeup but I can't be sure and don't have a JR apart in front of me currently. Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted October 2, 2018 Author Share Posted October 2, 2018 power connector feels loose in the back connection. Voltage Regulator doesn't heat up. Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted October 2, 2018 Share Posted October 2, 2018 then it is likely that the power jack has come lose from the main board. Can likely solder it back down but make sure you use a lower heat iron and the proper solder for it. New ones can be purchased from console5 for pretty cheap. Shipping will set you back more than the part will if that was all you purchased... https://console5.com/store/atari-2600-vcs-dc-power-jack.html Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted October 2, 2018 Author Share Posted October 2, 2018 The connection on the board doesn't move just the power connector.. Might been internal damage and the connector will need to be replaced. Quote Link to comment Share on other sites More sharing options...
Osgeld Posted October 2, 2018 Share Posted October 2, 2018 You can try popping the side window off (its heat steaked so cut those first) and try re springing the contact Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted October 4, 2018 Author Share Posted October 4, 2018 Hard to work on it with the mod wires keeping the top with the board. Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted October 4, 2018 Share Posted October 4, 2018 Should be able to flip the top cover over to the side while still attached so you can get at the power jack? But...because of wiring being in the way is one of the reasons why I use header pins and connectors for most of my mod work I do now. Makes it easy to disconnect without having to desolder anything.

bradhig1 Posted March 15, 2019 Author Share Posted March 15, 2019 put a new power connector in and while doing that the stupid mod wires broke off. I repaired them but no power no picture nothing. I don't have a clue what is wrong and this is because some stupid cables tried out for Tangled rather then stay nice and neat and pulled the power connector when I picked up the joystick. The stupid mod connections couldn't be unscrewed and that is why the wire broke. I don't even know if they are connected right. Everyone else's atari could have the cable tangle and pull the joystick free and their's would still work. . The ribbon cable is also problematic because it won't stay connected. Now two of the mod cables are broke again. I am sick of this. I want an atari that will always work no matter what happens to it. Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted March 15, 2019 Share Posted March 15, 2019 (edited) The wires on the connectors look to be in the right places based on the earlier pictures you posted in that the Yellow is the Ground wire and the Blue is the video. So the Blue wire should be on the center of the yellow RCA jack, the Red on the center of the Red RCA jack, then a piece of wire likely goes from the center of the red jack to the center of the white jack. Then you have the yellow wire that should be attached to any of the top tabs of those connectors since all of the top connection tabs are ground. It does look like quite a bit of the PCB might be burned away from around the power jack though. Especially the ground connections and that might be the issue for still not having any power. Also, is it just the angle the picture was taken or is the ribbon cable melted in the right center of it? Looks like one of the traces just ends abruptly? What happened with the heavy sixer I fixed up for you like a year or two back? I know it wasn't AV modded, but that was just some light trace repair it needed on the voltage regulator to get it going again. Also, it is important to keep in mind that these consoles are over 30 years old. That alone means they are going to be more fragile than when they were new but they were still built in a time when electronics were made to last vs today. That being said, these consoles were still built by imperfect beings. They won't last forever, but with care and knowledge of how to keep them going, they can last a very long time. But everything has their limits to how much stress and wear they can take. The fact that so many 2600s are still in working condition this far in the future is pretty cool honestly!

I just wanted an A/V modded 2600. I am thinking the voltage regulator may have blown. The power light doesn't come on when I turn it on. I don't know about the ribbon cable. Anyone have a photo of a working jr ribbon cable? Edited March 16, 2019 by bradhig1 Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted March 17, 2019 Author Share Posted March 17, 2019 I got it working now but i need a new ribbon cable because select and reset don't work. Anyone know where I can get one? Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted March 17, 2019 Author Share Posted March 17, 2019 The unit is dead again. I swapped the voltage regulator and it powered up and died again. I put another voltage regulator in it and nothing. Now the stupid mod wires connected to the a/v plugs broke off again and won't reach. I don't know what to do anymore with this uncooperative POS that needs to be pitched. Quote Link to comment Share on other sites More sharing options...
Jason_Atari Posted March 18, 2019 Share Posted March 18, 2019 Whenever i do an A/V mod on a 2600 i always make sure that the system is working 100% on RF first. If there are any issues thereafter you know it has to do with the mod itself, and then fault find from there. Quote Link to comment Share on other sites More sharing options...
