I'm converting a "War Final Assault" game to be captured, and after pressing "auto" I get a great color calibration.

Over time- (starting after about 5 seconds) my signal will drift almost entirely Red dominated. I've tried tweaking the R/G/B potentiometers on the converter board, but they only further distort the signal.

In your experience, does this mean I could have a weak splice? bad board? or maybe a power issue?

I'll upload a video.
 
Ah, more thread research revealed this solution:

"Set your Clamp st to 3 and Clamp sp to 4 and it should fix that issue. I had the same thing on a GBS-8220."

Which completely worked. Thanks!
