Problems with these TVs not turning on are usually capacitor related. Take the back off then look on the power supply where the power chord goes look at the fuse next to the plug. See if it's physically dark if so, the fuse is most likely blown and you should just look up the board number on E-bay for a new power-supply for a more costly, but easier fix than a repair shop. While the back is off, look for capacitors that are puffed and see if they need to be replaced. There are usually 2 caps by a heat sink that look bulged.
Should be enough info. If you're not into soldering and you feel comfortable replacing the board, there is this.
If this doesn't work, you're going to have to change the power supply. Or get it repaired for
I had this problem with a different brand plasma and it turned out to be cracked or missing solder on the power board lead to y sustain. I removed the power board, desoldered the connection, clean it up and then resoldered the connection. Everything works great now.
NC in the schematic is a NP (Non-polorized film Capacitor) each C6, C7 and C54 of the schematic above are NC caps as opposed to polorized electrolytic caps... Since the value isn't printed the requirement was replaced with an opposing cap, in this case with a polorized electrolytic instead. It is common to see these design changes and see them still noted in the schematic because they appear on the board. This usually happens when it was too late to correct the board or more costly to redraft the board to eliminate the pos#...
i know some things you can try one thing is try to power cycle the tv your goona want to turn the tv on the unplug the power cord from the wall then with that cord unpluged hold down the power bottom for 30 seconds.then if the problem still happens try some different cords then try resetting all setting if u can reset all picture setting another thing u will want to try is see if it happens on like a dvd player or sometype of other source like video game and if none of these trouble shooting tips work. then you might want to buy a vizio.
I suggest you unplug the set for about 15 minutes and then plug it in and try again. Sounds like you may have had a power surge/bump in the middle of the night. Althoguh you are using a surge protector, doesn'r mean the devise hooked to it can't lock up during a power surge.( Surge Protectors are an insurance policy only, not a garrentee ). If unplugging the set and waiting doesn't fix it, it will need to have the power supply section of the board repaired. Good Luck
