Our four year old Sony TV stopped working last week and using the internet I deduced that the power supply failed. The power LED was red and blinking in a two-blink pattern which indicates a power supply failure. After trying several methods of getting it fixed I settled on an eBay vendor in Alhambra, CA that fixes the boards for our model "when the red LED is blinking twice". I contacted them to check on the procedure, clicked to buy it, and dropped the boards off at FedEx.
Now we wait.
The back of the TV is off to expose the boards. There is surprisingly little inside the case.
