There is no lamp fuse in this type of TV. I will check on the error codes for this set and get back to you.

SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206. meaning look up a repair guide on the net and check to see a solution i dont know what the solution could be due to me not seeing the tv and actually hearing it im sorry but ill let you know if anything changes

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


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.
