So I'm working on a RCA 721 the Table top model
I've checked components and most of them seem to be OK, I can't seem to find what is causing this symptom, I just got a lead on another set of the same model and want to get it working well again.
This one was used as a interactive history display and it always had this flickering, was on for about 6 hours a day for a month. now its back with me and I wanna get it back to 100%
This is what its doing
