82atari5200 Posted May 23, 2013 Share Posted May 23, 2013 Went to mod my 5200 with a/v mod. After splash screen locks up. I've replaced all the main chips, all the ram chips, and the 4050 hex buffer all to no avail. Any suggestions? It was working before the mod and the mod works with another 5200.

ApolloBoy Posted May 24, 2013 Share Posted May 24, 2013 Check to see if you have any shorts on the 5200 and I'd also check the voltages coming out of the two 7805s. Quote Link to comment Share on other sites More sharing options...
82atari5200 Posted May 24, 2013 Author Share Posted May 24, 2013 There are no shorts. I'll try checking the voltage reg. But It does turn on. It displays the splash screen and then freezes or sometimes displays garbled text. Quote Link to comment Share on other sites More sharing options...
