Robotrex Posted August 25, 2016 Share Posted August 25, 2016 Hello everyone, I recently picked up a sears telegames 6 switch Atari 2600 at a flea market. When I got home to test it out, it had this weird screen issue that I had never seen before. What happens is that when I turn the system on, only the top right 1/4 of the screen appears, then after 7/8 of the screen is drawn in about 30 seconds it then stops. Also the video is black and white. I can't even see Pacman. And when I switch to console to black and white, the screen displays a different "shade" of black and white so I know it's not the switch. But my main issue is that I have no idea how to fix this. I've attached a picture of the screen when it is "done" drawing for reference, and the picture is when the console is set to color. I have opened up the Atari and nothing seems wrong. No broken solderer joints, no burst capacitors, the cartridge slot has been cleaned. I have tried other games as well and they all don't display correctly either and have the same problems and they all work fine in my colecovison expansion module. I've tried a CRT and an LCD television with the same results and I'm using an RCA to coax connector instead of the RF switch. Heck, even the ac adapter is a new 9 volt plug from radioshack that I use with my pong console, and the RCA cable I'm using is new. Sorry for such a long post but I wanted to cover all my bases so people know it's not something obvious. In short, I have no clue what's wrong and was wondering if anybody could deduce the issue of this console? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Robotrex Posted September 2, 2016 Author Share Posted September 2, 2016 After farther research, it seems like my issue might be related to my TIA chip in my console, since it generates the screen display. I guess I could try and replace the chip, but it would be nice to know that was definitely the problem before I that. Quote Link to comment Share on other sites More sharing options...
Thomas Jentzsch Posted September 2, 2016 Share Posted September 2, 2016 If it happens on multiple TV, then it sure looks like a faulty TIA. Quote Link to comment Share on other sites More sharing options...
