Screen went completely white today and all three CRT's were brighter than heck so I shut it down. Problem seemed to start when vid out to CRT boards became disconnected during a convergence adjustment. Obviously I reconnected the cable, but the unit would not work right since. It almost seems as if the CRT's are getting too much voltage, though all of the video output amps to the CRT's tested OK and the resistors on the boards are within spec. This TV has not had any problems except for IC's and coolant which were both replaced this week. I'm hunting down schematics now. Anybody have any ideas or experience similar problems?
