9 blinks means, "Zero Crossing Detector" and the probable cause locations listed are "D6166 or D6114 is open (G board)". I had the exact same problem so I just ordered a new G board and swapped it with the old one and now everything works fine! You could order a new one at this site: http://www.partstore.com/PartSearch.aspx?PartNumber=A1054157A&x=31&y=19. The Sony board number is A1054157A. Replacing the G board is rather simple; all you got to do is pull out the back cover of the TV and the G board is the first board on your very left. After that unplug the four connectors and replace it with the new one. Here is a picture of the G board inside your TV: http://img47.imageshack.us/img47/8396/backev6.jpg. Hope this helped!

If the Diodes are not open then you need to remove all the existing solder with solder wick and clean the diode leads and re-solder.I have fixed 2 other sets this way.Sony used solder that was not very good at the time. And they are on the G board part of the input power.

Diodes D6116 or D6306 is open on the D board. thats usually what causes that error code.

Is the light blinking 9 times? If so thats a very common problem caused by failed diodes on the G board which will need to be replaced.

I have a Sony Kp-51ws520 5 blinks


Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

Sony kp-51ws520 when turned on just has standby light flashing . the rest is all dead, no picture or voice.


Standby flashing light shows that tv got some internal problem. How many times standby light is flashing is info that provide info about what section of tv got problem.
Count standby light blinks and let me know, there would be 3 seconds long pause in blinks so count pause to pause.

The standby light just blinks when i try to turn it on and it wont turn on


Count the number of blinks of the standby light. It will bink a count, pause and do it again (Common counts are 2 -9) Give this count to a Sony service center and they can help you know what the issue is. (Probably the lamp)

2004 Sony 52" Wega dont turn onnthe stand by light stays flashing. This TV first started by taking long to turn on and now and then would turn off until one day it just didnt turn on and the standby button...


When that model Sony shuts down the LED starts blinking as you say but it is telling you something because it blinks a certain number of times and then pauses and repeats the number of blinks. Count the number and then I might be able to help you narrow down where the trouble is.
