Sony KP-57WS520 57

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,

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.
