racer raul Posted November 4, 2008 Share Posted November 4, 2008 This is the mod that I did on my 7800... http://www.geocities.com/atari7800mod/7800...nstruction.html The system still powers on, and I get video out from the factory output... Any gurus out there that could help me figure out what could have gone wrong, before I set out to rebuild the video board again? Quote Link to comment Share on other sites More sharing options...
racer raul Posted November 6, 2008 Author Share Posted November 6, 2008 (edited) I have a multimeter, and was hoping to get some input from the gurus out there as to what to check for and where... Here is the schematic... Any help is appreciated. I'll start with the ground... the EZ shtuff... and report back.

racer raul Posted November 10, 2008 Author Share Posted November 10, 2008 Well got it started working after I checked all the ground... guess I have a loose or bad solder connection somewhere... Quote Link to comment Share on other sites More sharing options...
