I had a power surge hit my home and my TV no longer powers on, but the Vizio standby lights up. I followed Vizio's reset procedures and did a flashlight test in a dark room. There's nothing but the Vizio standby lit up. The Vizio standby used to blink when I power cycled it in the past. Checking online and youTube, it might be, Vizio XVT473SV INVERTER 0500-0712-0020 PCLH-A952A, or Vizio 0500-0512-0810 Power Supply Unit. Any help on this would be greatly appreciated. Thanks!
I would say its most likely the power supply. Quite often after a power surge this can happen. Another option could be that the surge just blew the fuse on the power supply board and replacing that may be all you need. That said, usually you will get no signs of life at all if the fuse blows.
If the standby light is on its not a fuse, see if your getting the PWR-ON voltage, if so then test your various power supply voltages and see if they are ok

Check out Ceramic Capacitor C514 by the horiz. output transistor (burned/shorted?) My question is how do you find the specs of the capacitor and where do you buy one?

This set has a power supply and signal PCB. Since the indicator light is blinking, I would consider the problem to be a missing voltage from the power supply. Unplugging the set for a couple minutes may solve the problem. If not the set may still be under warranty. Contact LG (800) 243-0000 for a servicer in your area. Hope this helps.

Did you ever find anything out about this? I have a pt-53tw53g with the exact same problem, and I've been unable to find out what the three flashes means.

hi, i have read somewhere that you need to replace both 100u / 25 caps aswell.
the info came from a user on here called PaleFace but i cannot find the original post now and i have the same problem with my tv.
SOURCE: vizio 37" no longer turn on
It depnds, if the board is labled with voltages at the DC output connectors or not, if not, you will have to trace out the connection to find out which one is 5vdc standby, switched 5vdc, 12vdc, and 24vdc (I have to do that all the time when I work on circuits without diagram).
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:
