I tried the video mod and got the same result. I'm guessing the chip is bad. Time to call the Bones McCoy on it sadly. It's dead Jim. Thanks for the helpful suggestions.

Thanks very much for the link. When you did it did you lift the traces or leave them down and build the circuit?

Console Repair/Mod Center / Turbo Duo Video Problem. Please help.
11/17/2013, 11:06 PM
Hello. First off I have been reading these forums for a while and am very grateful for all the knowledge and kindness that is shared. I have worked on a lot of systems and a lot of pcengine/turbo grafx systems and have never seen this so I hope a fresh set of eyes can help. I was given this duo to do a sound cap replacement. I noticed quite a few more caps that looked bad so I replaced those as well. I put a game in and let it run for a while to test the sound and after a bit I noticed a flash in the video and the it looked like a scrambled cable channel. I have tried everything I can think of and have searched the web and can't find any other topics on a problem like this. I tapped pin 44 of hu6260 and attached it to the composite to even get the stable image shown. That image seems to have no white at all. Any help would be great as I hate to tell the guy his US Turbo Duo is shot. Thanks so much.
