Re: vizio vf55 power surge
just on another site and they stated that the 12v and 24v or any of the high voltage does not come on until the TV is turned on, and that my problem is most likely on the main board. what do you think?

vizio vf55 power surge
I have a Vizio VF550XVT1A - Had a pretty good lighting storm today TV was on and power cycled very quickly, "VIZIO" flickers continually, unplugged for 10 min. no help. everything i have read online says the main board needs to be replaced - main board 3655-0012-0150(2B)
I am good with a soldering iron but only have multi-meter. I am willing to replace the board but would like to be certain it is the problem. 5V to main board is good.
Any help would be greatly appreciated, don't mind smart asses...
