Question about Sony Grand WEGA KDP-51WS655 51" Rear Projection HDTV

1 Answer

Sony KDP-51WS655 Our televesion has had several very loud cracks and then the picture went blank, but the TV turned itself back on again. This happened three or four intermittent times. The last time it happened it never did come back on and now when we press on it clicks like normal, the red light blinks a little bit and it clicks off. What should we do or who should we call?

Hello, I have a problem with my sony rear projection tv. When I try to turn it on the standby lights blink but it odes not turn on. I turned it on using display 5 vol- power and it did turn on and know it...


You need to count the number of blinks between the pause. Most common is 9 blinks. Also- after you press POWER, do you hear a "click" or not? If no click and 9 blinks, you probably have a "zero cross failure" and have two options:

(1) Replace the "G" board (part # A1054157A) or have it repaired (they repair it on eBay for about $40. You ship them the bad board and they either repair and return or ship you a different repaired board) A new board costs about $80- without having to send them your board.

(2) Repair the board yourself- by replacing the two diodes on the "G" Board - (D6301 which is on top- by the small transformer) and (D116 which is an SMT component on the bottom of the board- it takes VERY steady hands and a good solder iron). The parts should cost less than $25 and are available on eBay by searching for "sony a1054157a".

Sony kdp-57ws550. Turn on tv = no picture, have


You have to count how many times it blinks. It is a service code. The main thing that goes on these is the convergence chips. If you had the back off doing any type of repair, recheck your plugs. Odds are, you crossed one.

Model KDP-51WS655 - blinks 9 times


A 9 flash code is defined as a zero cross failure, basically a power supply fault. It is usually caused by the failure of one or two diodes on the G board D6301 or D6116. D6116 is 871908197 and D6301 is 650056721. If you can get them and are handy with a soldering iron, you can probably replace them. Be sure the set is unplugged and use care when installing them, as high voltages exist in the set even after it is unplugged. If this answer is to your liking, please be sure to rate it. Thanks! Also, a good confirmation of this is to turn the set on using the following error code display method. With the original remote, press the following buttons:
DISPLAY
5
VOL -
POWER
The set will usually turn on this way if the diodes have failed
