Your main board is faulty. I've done several of these but haven't been able to figure out which component is actually bad these yet. I've simply had to replace the board itself, and it fixes it every time. One thing you can do to get your backlights to come on (and so you know I'm not Jive'n you) Is unplug the three wire bundle that spans from power supply to main board. This will usually make the backlights fire up. I even had one that after I left it that way for a minute (with the backlight on) it suddenly started working again! But this was short lived. :-(
One time I even tried recapping the entire main to see it that would fix it. It did not. I think it might be something to do with the small chip labeled SL37HA37. It's a 16 legged bastard near the 3-wire plug I told you to pull. It's that or possibly the bigger IC near it that has a heat sink on it. The ball grid array solder joints may be faulty. Just guesses, if any smart guys out there figure this one out, be sure to tell the rest of us please!

Ok so what is your question exactly, I do not see a question in there?
SOURCE: I replaced the main board in my sony Kdl-32S300.
B+ over voltage protection (OVP), unit goes to the standby mode then
displays the 3 blink fault. This is also a problem in the power
supply circuit, check T603 and R672.
Have you set the output voltage correctly?

Welcome to the world of Sony **** Bravia and their **** customer service. You will find this is a HEAVILY reported problem and Sony will gladly ignore it and expect you to cough up $200 to trade out a 2 year old TV. Yes, it is the IR board. Yes, I will never buy another anything Sony.

Check BL_ERR pin on back light inverter board, what is volt reading that you get before and after tv shuts down? Let me know to proceed.
Thanks.
BTW, I really enjoyed your quote * I don't trust the blinking anymore *
