Bob suggested a bad relay, which it was.At least for the filaments
remaining on. I'm going to do the IK modification this morning.. It has
a great picture, but will take up to 3 minutes for the picture to come
on from a cold start.
I just have to find the correct pin numbers on the IC to cut the trace
and add the diodes.
Do you have a partial schematic on the Video/chroma IC for that set? I
don't know which pins to use on that IC.
