Well the pic was bearly a shadow of something but really couldn't make it out. The sound was clear and it was from a source, cable with the matching transformer so it was a good signal. The screen is lit but blank and snow for sound. I traced the 33v source right to the tuning knob or whatever it's called it also has the 45v source. I changed the caps on the video-IF board but nothing helped at all. I just thought there may be a common thing with these sets. It makes no sense , sound then nothing after putting new battery's in and I also took the battery's back out to double check that I didn't hit something in there but it was all good and intact. One end of the 33v is at the IF then to an IC then out as 45v but the 33v does branch off also but there are no bad traces, checked them all.
