Eprom failure most likley so the main board will need to be replaced. I would send a email to customerservice@tvrepairworld.com to see if they have the replacement main board for your model they should have it available.

SOURCE: Tv won't power up after power went out

Most likely your TV's power supply was damaged with the power surge. You will need to take it to a repair place and have the supply checked out and find out the cost versus the value of the TV. I hope this helps.

SOURCE: no picture or sound, light comes on in the front and have to unplug tv to turn it off.

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

SOURCE: My vizio e420vl turned itself

There are at least two power supplies in any set with remote capabilities; one is on any time the set is plugged into AC and is supplying that indicator and the receiving circuit of the remote, otherwise it wouldn't turn on under normal conditions. The second power supply produces the needed service voltages used when the set is in use. This second supply is a common failure in many sets and it is generally traceable to poor design and the use of low-quality components of a certain type. Vizio may have a repair or exchange program through their service center. I would guess the cost will be between $50-$150 and you might remove the back panel of the set and look for a smaller board with larger-than-average parts on it and is related to the AC cord coming in. It should be fairly easy to remove and replace as these are often outsourced and just plugged into the rest of the set with dissimilar plugs making it simple to install and reinstall.

Look inside for a block assembly with larger components and several connectors that is bolted onto a larger panel.
These are purchased from other sources, not made by Vizio.

Look into the guts of this assembly for cylindrical components with plastic foil and an aluminum top, mostly mounted vertical to the board.

Examine the tops of these for any dome-like appearance; this is a sign of failure since these should be flat.
They are inexpensive (one reason they fail) and this failure can be prevented by spending another dollar or two in the manufacture of them.

Replacements can be had but unless a couple of parts are added (by the maker or a smart tech) the same failure will eventually occur.

Solutions (2) Best Solution That little fella is only turned off by unplugging it. If all those little lights in America could be turned off we could do with one less nuclear power plant. If unplugging it is not an option, my wife's solution is to cover it with a piece of black tape.

remove all screws on the back of the tv, carefully pull off back cover. you will see two circuit boards one on the left (Power) and one on the right (Video) on the Video board there is a small plug on the right side with a yellow, white and red wire going into a small white connector. the red wire is what controls the orange light on the front. now that the plug is pulled turn it over and you should see a small white plastic piece that holds each metal connector on the end of the wires in. pry this piece of plastic up for the red wire and pull at the same time, the wire will come out of the connector. now tape the metal connector with electrical tape and tuck it behind something or tape it to the chassis. plug your connector back in. put the rear cover back on. now your tv will only show the vizio logo in white when you have the power on. If you wish to disable the logo for both orange and white just disconnect the white plug completely.

TV won't turn off


Or ironically the power switch on the TV could be stuck and causing a false on/off command. Don't let the simple things such as that be overlooked.
