keoni29 Posted April 23, 2012 Share Posted April 23, 2012 I just bought a c64. It has some issues with the video. Some colors (especially white) flash in different colors. I already did the composite video mod, so the rf modulator is not broken. Do I have to replace capacitors?

bust3dstr8 Posted April 24, 2012 Share Posted April 24, 2012 Check the color rams, if they are faulty or missing signals you can get that flashing effect.

keoni29 Posted April 24, 2012 Author Share Posted April 24, 2012 Does the video signal generator use an external or internal dac? Also: all ceramic caps have some white oxidation on them Quote Link to comment https://forums.atariage.com/topic/196973-c64-bad-video-signal/#findComment-2507576 Share on other sites More sharing options...
keoni29 Posted April 24, 2012 Author Share Posted April 24, 2012 I will use this one for parts. Now I can finally make a SID midibox A lot of chips were damaged, so I decided that it would be better to just buy another one.
