You may want to run your TV set through a power regulator as your house mains may be not the full voltage or too much.

SOURCE: VIZIO 52" LCD is on display

If this is indeed an LCD and not a plasma, then you need to replace the LVDS (LCD controller) board.

SOURCE: My television shuts back off when i turn it on.

It may thing there is short circuits, so the power supply shuts down to protect itself from further damages. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
Please post back what you find.

If you leave the tv unplugged for 2 days (atleast) then plug it back in and try to turn it on and if it comes on its the power supply board. If it comes back on it will probably shut off between 30min to 4hrs and you would have to unplug it for 2 days again. All the power needs to drain out of the tv. If thats the case take the back pannel off and check the part number out on the internet. Not hard to do becarefull touching things the power supply does store a little bit or shock in it. Good Luck.

SOURCE: My 52" Vizio LCD (2 yrs old) has power but blank screen

Looks your power supply quit. Get a new one from might cost a buck and a half,plus an hour of labor, but 52"? deffinetly worth it! Vizio is good on parts. Make sure, have your serial# ready. some sets have been modified within a year, might get a wrong part without ser#.
Take care.

My LG 50" smart tv turns off right after I turn it on. The LG logo comes up then disappears then the red power light blinks twice and shuts off. The red power light then returns.

the number of blinks by model tells you information. Look up capacitor failures on that model on youtube. I have a vizio that did the same thing, and it was a $0.11 capacitor I had to replace... took about 30 minutes, and working great. You'll need to see if you can find someone with that same problem on youtube to be able to find it easilly... requires soldering iron... little screwdrivers and some patience. you can do it!

My vizio tv won't shut off and it will not work on any of the smart functions? I unplugged and left overnight and it did not help it. It is only 3 years old.

The board where the power button is located is probably bad. The power button itself will be part of that board, which will also have the other controllers (i.e. "all on one board"), which would explain your multiple problems.

No sound no picture vizio 52 inch 2 years old

That is exactly what it is. Mine, as well, (1yr and 4mos old) went out. But my sound, eventually, went out as well. However, I was lucky and had the two year warranty and it was covered. Apparently this is an issue. The fella's that picked up the TV made the remark that "this is another one". Starting to wonder about Vizio...didn't take me long to find several of the same issues as I was searching the net and within a short span of time at that. :o\
Good Luck!

Your TV is overheating.. easiest remedy is to point a fan at the back of the TV or... clean the inside of the TV, Im sure its full of dust and stuff... this prevents air circulation inside the TV thus creating more heat...

52 HD Samsung tv turns off

I have the same problem with my 56" HD Samsung. It shuts off automatically and then on the power button the word Lamp is light up in green. Sometimes I can turn it back on but other times it won't and I have to wait a bit. It's been embarassing a couple times when people were over for a movie. I believe it might be some kind of overheating problem but would like someone to confirm this.
