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.

Please provide SONY BRAVIA KLV 46X200A red standby led blinking error code meanings


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" or "Magazine" will make surf easy.

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.
