TV has been working great for the past 6 years, this morning when turning on the TV nothing happens except the standby light flashes about 9 times on and off. No click like I usually hear when turning on...


Hi Dave,

We have had this same problem twice now - the first time under warranty (no problem) and now currently. The 9-blink error code refers to needing to replace two diodes on the G board. Specifically, D6301 and D6116.

The warranty time, the repair guy came and resoldered the new diodes onto the G Board, reinstalled the board, and was on his way. We had no problems for the next 3 years.

THIS time I ordered the two diodes from Andrews Electronics (www.andrewselectronics.com) am removing the G board myself and taking JUST THE BOARD to a local TV repair guy. This is a LOT cheaper than calling Sears or taking the whole TV to the repair guy. Here are the links to the specific diodes:

D6301 - http://parts.andrewselectronics.com/search/electronic-parts/parts/7/6-500-567-21.aspx

D6116 - http://parts.andrewselectronics.com/search/electronic-parts/parts/7/8-719-081-97.aspx

They are a heck of a lot less expensive than other places and the customer service I received was great!

I hope this helps!!

Tv wont turn on


You have a zero crossing failure.

Replace diodes D6301 and D6116 on the G board with 1n4002 diodes.

No picture or sounds red light blinks 10 times


The parts you need are two diodes, D6301, D6309, and D6116, Sony part numbers 6-500-567-21 (D6301 and 09) and 8-719-081-97 (D6116), they are located on the G board, and that's located on the left side of the set, as seen from the back.

D6116 is connected to pin 9 of transformer T6101, and D6301 and 09 are in series off of pin 7 of that transformer.

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

Don't replace the entire G board! that is expensive! The diodes are available from MCM electronics and can be easily replaced.

Sony rear projection tv How to de-solder


I would suggest not to desolder that transformer until you are certain that is defective.
Try to change D6116 and D6301 first.
You can try Radio Shack or check this site.
Good Luck.
