The light is blinking a repeating error code. Try to determine the number of blinks before a slight pause as that will be an error code. Then respond to this same post and I will assist you with diagnosing what may be causing the set not to power up.
A single blink of the standby light is not used as an internal diagnostic count. If that is all you see, then there is likely a fairly major problem with the main power supply. Because of the lack of diagnositc information, this is not likely to be resolved remotely. These sets are decent sets and are worth additional diagnostic investigation. I would suggest you invest in a detailed repair estimate. Post the results here and we should be able to walk you through the actual repair.
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.
TURN TIMER OFF. GO TO SONY.COM, TROUBLESHOOTING, OR
The STANDBY light is flashing on the television and there is no picture or sound.
The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.
Turn off the television.
IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
Turn on the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.
