    When I turn it on, no power and no sound. The standby light initially
    flashes 10 times and then pauses for a couple of seconds and then
    flashes 9 times. Then it stays in the 9 flash, pause, 9 flash, pause,
    infinity loop.

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.

My kp-57ws520 standby light blinks 9 times tv does not come on any more it did for a short period of time


I had a similar problem with a sony 60" lcd hdtv. The normal power on light was green. When I had an issue the led would flash about 8 or 9 times. Can't remember exactly. It turned out to be a troubleshooting code. When I researched it, turned out to be the high powered lamp that lights the lcd screen was shot. When this happens you get no picture or sound. It's not a terribly difficult job to replace it yourself. I found a replacement bulb on line by my model number along with instructions on how to replace. You probably get about 4 or 5 years out of a bulb depending on usage. Hope this helps.

Hi,
The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.
Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
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.

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.
If the issue continues to occur, service may be required.

Thanks for using Fixya.

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.

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)

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.
