Question about Sony KP-57WS520 57" Rear Projection HDTV-Ready Television
The red led which provides the error code is in a steady blink pattern. I am a technician so I believe with a little guidance i can resolve this situation all technical intelligence will be understood so shoot away with the lingo im ready. Not a tv tech but i am an electronics tech just need to be pointed in the right direction.
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

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.

Testimonial: "Unfortantly didn't do the trick, during quite a few adjustments as you suggested, I would get a error code 10. Any feedback on this new code?"
