KP-57WS520 Sony Projector - No picture


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.

The 9 blinks on your TV means:
+/- 19V line is shorted
IC708 could be defective
PS701 or PS702 is opened.

To do this repair you will need to have basic electronics knowledge that includes hand soldering, use of a DVM and be very careful when working around high voltage.
