AtariBrian Posted December 30, 2017 Share Posted December 30, 2017 I have my friends av modded Colecovision but it has video problems . So I think just the vdp chips need replaced . It is not the power supply . Would anyone want to replace the chips that knows how to solder ? Quote Link to comment Share on other sites More sharing options...

NIAD Posted December 30, 2017 Share Posted December 30, 2017 Looks like a RAM chip(s) issue. Send Yurkie a PM for repair info. Quote Link to comment Share on other sites More sharing options...
Mauro72 Posted December 31, 2017 Share Posted December 31, 2017 I'm agree with NIAD. I think VRAMs chips is the problem. No VDP. Quote Link to comment Share on other sites More sharing options...
