    My father is wanting to repair it himself. He does have some knowledge of television electronics.

    Thank you so much I will look into that. Also last night it started blinking 5 times then 10 times. So I'm assuming 5 blinks means another problem?

OK, 10 times is HV protection (High Voltage) and problem can be in D board and Q8013, Q8014 can be shorted along with R8051 open.
also IC8005 can be damaged.
All above parts on D board.
I would recommend to get related service manual for proper diagnose of problem in TV.
Good luck.

More info please. I assume you have a new Sony lamp installed? Have you closed the outer door for the lamp? When the set fails to turn on, does the front panel light blink a certain number of times? If so, how many blinks?

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.

I have a TV sony KP-fx432 sometimes it works normal but the other times it doesnt and the led blinks 10 times there is sound but no picture. please HELP! :[


We had a similar problem with the same model a few weeks ago. With the help of a service manual, we just replaced IC8002(MCZ3001DB) on the D-board to solve the problem. The 10 blinks indicates an HV protection has occurred.I do hope this helps.

Sony - Projector TV won't turn


Sony TV;s will give a service code, count the blinks, eg; 2-6, light will blink X amount of times, hesitate & blink again so many times. Count and report back but, I would recomend to unplug the TV's power cord, to reset the TV's system. Unplug for at least 3 minutes. I hope this was helpful.
