kp57ws50_57_in_rear_projection_hd_228277.jpg Problem with Sony KP-57WS520 57 in. Rear Projection

This model is really prone to one problem in particular--screen even briefly comes up bright red, green or blue and set shuts down.

15 seconds from turn on front power light should blink as set checks several things internally---if something wrong it does not let picture show.

Usually after shut down or failure power light will blink a sequence of blinks but not always depending on problem.

Did you see the screen at all go red, green, or blue before?

the more you tell me the better I can help

KP-57WS520 Sony Projector - No picture

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.
