Sony Bravia KDL 46", no picture, standby light blinks 4 times

I have a Sony Bravia 46" (KDL-46V2500). I've had the TV less than 2 years, and I've had the same problem. Immediately after powering on the TV, the yellow/green power light goes out and the red standby light blinks 4 times, then pauses, then repeats. I submitted a support case with Sony, and I received a very generic, canned response, whereby they asked me to contact an Authorized Sony Service Location. After doing some research on the Authorized Sony locations, it seems as though the cost of the service could be offset by buying a new LCD (different brand of course).

I remember from working on some Dell's a few years ago, that there was a problem with capacitors on the motherboards, whereby the caps would bulge and eventually seep. So as a Hail Mary pass, I removed the outer shell from the rear of the TV searching for a board with similar caps, but to no avail. I went ahead and replaced board 1-871-504-12 because it was cheap enough for a one time effort ($135.00). After re-assembly, still the same problem. I don't have the cash to exchange every single board until i get the right one.

In short, thanks Sony. I will be sure to share my story with as many people as I can. I have a Sony Bravia 46" (KDL-46V2500). I've had the TV less than 2 years, and I've had the same problem.

I determined that it must be the motherboard, and would have replaced it myself, but Sony did not sell it separately. The sold only an assembly which included it. It cost hundreds of dollars. I paid a repairman to fix it I determined that it must be the motherboard, and would have replaced it myself, but Sony did not sell it separately. The sold only an assembly which included it.
