minutes the picture came back on and it was fine.....

Until tonight. Again same thing happened but this time it hasent fixed
itself. From reading other posts it goes on about CRT drive. Can
anyone
clarify if this is the problem?[



color drive transistor in the crt
socket is bad.i have the same problem as you have few months ago.and
i fixed it by replacing the transistor.check the voltage under green.

Could be the socket, the drive transistor, a solder connection, or the crt
itself shorting internally heater to cathode.
