AL01 Posted July 17, 2016 Share Posted July 17, 2016 Hello. I am need of help! I have recently modded my 2600 to use AV and although I am getting color, the screen flickers like nuts... This mod required the removal of the resistor R209 and the transistor Q201/2 - I had to jump R209 to get color so I though maybe R209 was at fault - but tit was dumb luck that I did not throw R209 away so I tested it out, and the same thing happened so I know that R209 is not at fault. I decided that maybe the TIA is at fault so I bough a TIA Chip and it did not make a difference. Please help... Thanks!

AL01 Posted March 21, 2017 Author Share Posted March 21, 2017 SOLVED: System needed caps, resistors, and a new crystal. Total cost was about 10$. 1 Quote Link to comment Share on other sites More sharing options...

AL01 Posted March 21, 2017 Author Share Posted March 21, 2017 A few died. They were on the board. I had to readjust some of my solder jobs to. Just keep in mind that these Ataris are a good 35 years old. Most of them merely need new capacitors and resistors. Impressive for such an old console.

mojoatomic Posted March 21, 2017 Share Posted March 21, 2017 (edited) A few resistors died? Which ones specifically? Edited March 21, 2017 by mojoatomic Quote Link to comment Share on other sites More sharing options...
AL01 Posted March 22, 2017 Author Share Posted March 22, 2017 (edited) Some were by the wire that I needed to connect to that area of resistors. I replaced the crystal with a new one and I replaced all of the capacitors and 2 chiclets. I highly recommend the AV mod because apparently, (after talking to somebody who repairs game systems for a living), many RF modulators on the 2600 are starting to die out. Specifically, I checked every resistor - whichever ones were dead, I replaced. I had to eventually send the board to a pro though, but I do have a decent idea of what he had done in order to solve this odd problem. He pretty much did what I was able to do, just at a more advanced level of proficiency. Edited March 22, 2017 by AL01 Quote Link to comment Share on other sites More sharing options...
AL01 Posted March 22, 2017 Author Share Posted March 22, 2017 I also took out the jump, the red thingy, and the plug for the RF cord. Quote Link to comment Share on other sites More sharing options...
