Question about Sony KP-51WS520 51" Rear Projection HDTV-Ready Television
When I push my power button on the Tv the standby light blinks 3 times and goes off.. Do you think you could help me find the part number? Thank you very much!!! Wayne
Hi Wayne, In most instances 3 blinks is a diagnostic mode indicator where the builtin protection has kicked in. Very likely a powersupply problem with the B+ over voltage protection (OVP). Should you venture to do-it-yourself, you can try a hard reset (unplug the unit from the mains for a couple of hours (about 5 hrs). Pls note: Most probably & in some models/version/firmware - Sony uses same model number but for different regions and/or different versions of the firmware and therefore the blinks may refer to something else. If a no go on the hard reset, normally, I would recommend the services of a qualified TV professional very familiar with your brand. However since you want the part numbers, I will assume that you would want to do it yourself. Try checking power transistor 6?? and fusible resistor 6?? (numbers may be vary) in the power supply board. Due to regional differences, version update and other factors, the actual part number and/or component value as well as board number/letter may vary. Your best bet would then be remove, test, replace. If removed and confirmed defective, you have the actual part number needed and as per sample. This is of course component level repair. Replacement power supply board may also available. Actual board number is printed on the board itself. Of course, the standard precautions must be observed especially in the HV area. Good luck and post back should you need further information. kind regards.

I found this online maybe it might help you:
Many of the later model Sony TV’s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it.
The timing of the blinking you see would be as follows: two to nine blinks, (depending on the fault), about a third of a second apart, then a pause for 3 seconds, then the two to nine blinks about a third of a second apart again.
Here is a list of the problems that might have occurred indicated by the number of blinks. The words in parentheses are those, which you will see for each of these faults on a diagnosis screen described later in this article.
Now that you know about these self-diagnostics, how do you use them? Say that you have a set with a black screen. You see that the LED is blinking four times. This would tell you that you have no vertical sweep, which is why the video is muted. If it was blinking 6 times, you would know that you have a horizontal fault. It's not a sure cure..
IMPORTANT: After you repair the unit, you MUST clear the values on this diagnostic screen. These codes do not reset themselves after the fault is corrected, so if you don't clear them, you'll be seeing "old" fault codes the next time you enter this screen. Clearing is done by going into the service mode (display, channel, 5, volume plus, then power ). Press 8 and Enter, which returns everything to the factory preset condition.
