BlimpPixel Posted March 16, 2018 Share Posted March 16, 2018 Anyone seen something like this before? Colors are being displayed all weird. Green is showing up as blue. Blue is showing up as pinkish purple. Not sure what else, but its trippy. Quote Link to comment Share on other sites More sharing options...

+save2600 Posted March 16, 2018 Share Posted March 16, 2018 Electrolytic Capacitors probably need to be replaced in your 2600. Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted March 16, 2018 Share Posted March 16, 2018 Or the power supply is going bad. Odd colors are typical when the voltage or current isn't enough to the 2600. You can actually simulate this with those voltage selectable adapters. Once you switch them down to 7v the Atari starts to give off strange colors.

BlimpPixel Posted March 17, 2018 Author Share Posted March 17, 2018 Interesting! Although Im not too sure either was the case, here. I honestly dont know what happened. The system wasnt working at all, and after a few combinations of chips from a donor board, I got that result. A different combination, and now everything works properly (correct colors being displayed). Hmmm Quote Link to comment Share on other sites More sharing options...
BlimpPixel Posted August 29, 2018 Author Share Posted August 29, 2018 I am having a similar issues with weird colors on a different Atari now. I replaced the VR and all capacitors, and tried different combinations of chips, and it’s not changed one iota. It’s a light sixer, and replacing the switch board with another doesn’t change things, so it’s apparently something in the chip board. It is not the power supply. Any ideas? This is making me batty.

Keatah Posted August 29, 2018 Share Posted August 29, 2018 Compare voltages against a working color-correct unit? Quote Link to comment Share on other sites More sharing options...
Video Posted August 29, 2018 Share Posted August 29, 2018 Any corrode on the board, or maybe a cracked trade somewhere? It could be making enough contact to complete the circuit, but at a reduced voltage. Quote Link to comment Share on other sites More sharing options...
alex_79 Posted August 29, 2018 Share Posted August 29, 2018 Dumb question: before replacing parts did you try to simply adjust the color pot on the board, right? Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted August 29, 2018 Share Posted August 29, 2018 Earlier TIA chips will cause odd color patterns to develop on the systems as well. I've changed out two over the years for this reason. 1 was from a light sixer, and the other from a heavy sixer. The games worked fine on them, but the colors were always off and no adjustments would being them in properly. It was slight color shifting during game place that made me look at the TIA themselves as the issue. Replacing them out from the TIAs I pulled from some 4 switch units got them up and looking proper again. Quote Link to comment Share on other sites More sharing options...
BlimpPixel Posted September 8, 2018 Author Share Posted September 8, 2018 Okay, I fiddled with it enough to get the colors to work, and just when I thought it was all done, I have a new problem. It's like the sprites are out of synch somehow. I noticed in Adventure that I couldn't pick up the key, and then in Megamania, my bullets were passing through the targets without destroying them. Whyyyyyyy. Any ideas on that one? Never saw such a thing before. Quote Link to comment Share on other sites More sharing options...
