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.

I have a Sony KP-51ws520. I cannot power on. says stand bye and blinks 9 times.PLEASE HELP it is only 5 years old and they says some of the parts are no longer available.


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.

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.

KP-51WS520 wont turn on - standby & timer lights on constantlly


You need to check supply volts on main micro IC702 on main board of Sony KP-51WS520 TV.
If you have experience of big TV repair then I would recommend to get service manual of TV from any online store and check above said IC supply volts. TV must give error by blinking light in case any problem in drive circuits and if main micro fried, no error signal will be there.

Sony KP-51WS520 Stand by flashes 5 times


When a Sony TV flashes five times, that means that there is an AKB circuit fault.
This means that there is something wrong with the video.
When you get this error, several IC and components concerning the video signal must be tested and eventually replaced.
