Question about Gateway GTW-P42M303 42 in. Plasma Television
SONY REAR PROJECTOR TV KDP51WS550-LED LIGHT ON FRONT OF TV BLINKS 10 TIMES-TV WILL TURN ON WITH SOUND BUT NO PICTURE FOR ABOUT 5-10 SECONDS THEN SHUTS OFF-I KNOW IT IS PROBABLY A POWER SUPPLY DIODE, CAPACITOR, OR TRANSISTOR, I JUST DONT KNOW WHICH ONE OR THE PART NUMBER. IF ANYONE CAN HELP I WOULD GREATLY APPRECIATE IT. MY KIDS ARE GOING CRAZY WITHOUT WATCHING THEIR CARTOONS!
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.
