Hi, I have Sony KP-57WS520. It stops working. I followed all the trouble shoots from the user manual, but the Stand by light still blink 9 times then stop, then blinks same pattern again. Please help for solutions. I can sold or de-sold or replace circuit board if you tell me what to do and where to bay them, if there is a need. Thank you very much, SV [email protected]
The 9 blinks on your TV means:
+/- 19V line is shorted IC708 could be defective PS701 or PS702 is opened.
To do this repair you will need to have basic electronics knowledge that includes hand soldering, use of a DVM and be very careful when working around high voltage.

Hi, I've found a link from Sony that has your owner's manual for that set. I found on page 56 of this file a section on trouble shooting that covers your problem.
The buzzing sound you hear is typically the FBT shorting out when you turn the TV on. If you open the back panel and watch the FBT as you try to turn on the TV you can see it shorting out. It will be obvious.
on your model which is a RA-1 chassis the power light blinking steady just means the standby voltages are operating, so you will need to trouble shoot the power supply. you will either need the service manual or training manual to trck down the faulty component.
my sony kp-61hs30 displays that there is no siginal, also the red indicator light blinks when the power is turned on but goes out i have dirct cable pluged into the set and up until about a week ago it worked fine.All of the other tv's in my home work fine so i don't understand what the problem is . I have a dvd player connected to the set and it works great for viewing dvd's please assist with me with some trouble shooting points
You are going to need a service manual to trouble shoot your set. You can get one at the folloeing link along with online support. http://servicemanuals.vstore.ca/
