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!

SOURCE: Sony Wega stanby light blinks 5 or 6 times

When a Sony TV flashes five times, that means that there is an AKB circuit fault.
Six blinks is also a fault related to video problems, and regards a fault concerning the digital board and the Jungle IC (the main CPU).

This means that there is something wrong with the video.
Try first unplugging power for few hours, if that does not work, call a technician, as several IC and components must be tested and eventually replaced.

SOURCE: I have a Sony KP-51ws520. I cannot power on. says

Those LED flashs are a fault indicator...First thing to do is to try a reset:

With the TV plugged in push and hold down the reset button on your remote then press the power button on the the TV and then release the reset button once the screen has come up.

9 blinks means, "Zero Crossing Detector" and the probable cause locations listed are "D6166 or D6114 is open

If you are handy you can replace D6301 diode and it fixed the problem. You can buy that diode at partstore.com for $3. good luck





If still no luck then this is going to require a serviceman.

Hey i have a sony kp-51ws520,, an its standby light is blinking 9 times .. but i can play with the remote every now an then an it will come on ..nothing wrong with picture or sound. can you help me out


The G board has a diode #6301. This board is a tan color farthest to the left. I went to Radio Shack and bought a 200V 1A silicone diode and replaced it. Worked like a champ. You will need a 15W pointed tip solder iron and a steady hand. You can replace the board if you like. I found one for $70 on ebay, but the diode is $1.

WHEN I TURN IT ON ALL THAT HAPPENS IS THE STAND BY LAMP FLASHES 9 TIMES THEN PAUSES


Diodes are blown on the G board (Power) which triggers the zero cross error. replace the G board or have yours rebuilt.

Tv wont turn on


You have a zero crossing failure.

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

My SONY TV (KP-51WS520) will not turn on...


a Diode allows electricity to flow in one direction and blocks it in the other direction. So when its open means its burnt out and nothing can pass through in any direction. they will need to be replaced.
