Sony KDP51WS550-LED light blinks 10 times

Sony KDP51WS550 Rear Projector TV turns on with sound but no picture for about 5-10 seconds then shuts off. The LED light on front of tv blinks 10 times. I know its probably something wrong with the power supply, but I dont know if it is a diode, capacitor, or a transistor and the part number. If anyone can help it would be much appreciated. My children are going crazy not being able to watch their cartoons in the morning. THANK YOU

This is usually a problem on the high voltage board. When you first turn it on, the main board does it's P.O.S.T., then powers the HV board. You'll be hard pressed to find a replacement for it. You MIGHT find someone that can rebuild it, but for the money? Time for an open box special at you local electronics place.

SOURCE: SONY-LED BLINKS 10 TIMES

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.

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.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Tv turns self off when turned on


Does it blink a certain amount of blinks pause a second or just blink constantly with no pauses? Let me know it will blink a code if its going into protected shutdown. And it will blink constantly for another reason.
