Can someone repair a Colecovision for me

[AtariBrian]

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 ?

Hit up Bmack36 and see if he has time to do a repair!

Looks like a RAM chip(s) issue. Send Yurkie a PM for repair info.

I'm agree with NIAD. I think VRAMs chips is the problem. No VDP.
