    I have the same problem with the blinking 9 times, pause 3 seconds, then repeats cycle. I have called a repair shop and am waiting for a technician. What can cause this to happen? The TV sits in my unfinished basement and is rarely used. Maybe 2-3 hours a month. The TV itself isn't more than 3 years old. The kids went to turn it on one day and nothing but blinking lights.

A common problem for this error code is D6301 on the G board leaking under a load. D6301 is a Pt# 10erb20 -tbs.. This is neither an expensive part or that difficult for a quality shop. Kind of a no-brainer repair... But getting at the G board might be difficult if you don't have the technical experience. Personally I'd recommend taking to a shop if you haven't repaired many of these Sonys before..
Have a great day!

Don't replace the entire G board! that is expensive! The diodes are available from MCM electronics and can be easily replaced.

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.
