Sega Genesis Model 2 with colors messed up

Hello everybody,

Recently I got a free non-working Sega Genesis model 2, after some tweaks i brought it back to life but there's a remaining problem with the video output.

Everything else works fine (sound, graphics, controls, gameplay...), but look at those pictures:





The Green and Blue channels looks fine, but the Red channel is completely absent.

Any possible fix for this problem?

Thanks in advice

 

Sure. Start checking everything from the video encoder to the mini-DIN connector for faults then work backwards from the red in line.

 

Thanks i'll check it
