Google first the model number to find the full service manual with error codes and schematics and parts lists--I have seen it out there--problem suggests a power supply issue and that board (far left as seen from rear?) has voltages marked right on the board for most of the major plugs----you should be able to remove the board with power cord attached and do static voltage and resistance checks that way.

SOURCE: Power LED blinks red

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

Don't replace the entire G board! that is expensive! The diodes are available from MCM electronics and can be easily replaced.

Hi,
5 times blinks shows incorrect white balance (AKB) error. TV needs Screen Volts (G2) adjustment.
Take off lower front panel, find Focus Block that has 6 control knobs, adjust Screen volts of each CRT (red-green-blue) and problem will be solved.
Be Careful while working in TV.
Let me know if you have further question.
Thanks.

1 Answer

Standby light blinking


Set has problem in one of the circuits, possibly sweep or video. All modern sets have a diagnostic mode when turned on, such as flashing standby LED. If there is a malfunction, such as a voltage loss or short in one of the circuit boards, the power supply will prevent further damage or fire hazard. Take unit to pro/tech for repair.
