HI . Apparently for what you say the source is protected. TEST CHANGING TR DE SH. AND IF YOU PERSISTS THE FAILURE. TRY TO CUT THE AUDIO OUTPUT POWER TO SEE WHAT IT DOES

Hello Friend. So you indicate there are many cold welds. Start by solving the choper pins and check the filters that are after the choper, and solve the ic pins. vertical, and solved the micro pins, and those of the flayback and the small and solved regulator pins the trc insert. that is the tube. and check the target the target that is in that insert. It may be sulfated. and if there are bulging filters on the plate change them. luck and regards
