Dennis90 Posted August 30, 2016 Share Posted August 30, 2016 A PAL 6 switch Atari 2600 console I have is acting weird, the whole screen flashes when you press the fire button on player two's controller, and when you hold the button down you can see the picture like get a little bit brigther, and as soon as you let the button go it's normal again. I have tried diffrent controllers and swapped out the three main chips, the CPU, RIOT and TIA, but I still got the same problem. Anybody have an idea what the problem might be? Everything else works fine with the console except that. And it is AV modded btw if that has anything to do with it, it's modded with a transistor and two resistors.

zylon Posted August 30, 2016 Share Posted August 30, 2016 I'd suspect a bad cap in the trigger lines or a failing hex buffer. (that's the smallest of the IC's) Quote Link to comment Share on other sites More sharing options...
Jason_Atari Posted August 31, 2016 Share Posted August 31, 2016 Gee that's a weird one, was it working ok before you av modded it? Quote Link to comment Share on other sites More sharing options...
Dennis90 Posted August 31, 2016 Author Share Posted August 31, 2016 Zylon: You mean like one of the caps that sits right behind the controller port? And aha yeah, or mabye it is the HEX chip, but guess i try to replace the cap first and see if it gets better.Jason_Atari: I am not sure, i just tested the console a little before i modded it to see if it powered up and stuff, but guess it mabye was like that before.
