    i have the same problem with my new 42" 3D Vizio (a few months old). It's happened ever since i've had it. Just like u said... turns off automatically within about an hour of turning it on (regardless of the time of day). I also have to wait a few seconds before i can turn it back on. then it won't happen again til the next time i turn it off/on. very annoying. it used to happen sporadically, but now it happens once every day.

  • I have the same model as you. 42", 3D, Vizio. Had it about 3 months now. There is no order or consistency with it. Sometimes, it'll be on for hours all day long, then another time, it was on maybe an hour. I am sure it has something to do with heating up, power consumption, etc, but it seems like a flaw. Are there any VIzio forums that address this? I am going back to Costco to return it.

If I have trouble with a brand new TV I always take it back and am sure to get another brand entirely. Personally I've had good luck with LG, SEIKI, and Samsung.

My vizio 32 inch LCD tv shut itself off after being on for 5 hours tv was not hot I finally got it to turn back on after 15 minutes since then it has been fine what could have caused this


Set may have like a car with a check engine light have detected something and shut down as protection-----monitor it and if it gets worse or repeats consider having a shop examine it.

I would suspect issue is or was on power supply board.

I have a Vizio VF550XVT1A. First problem was a flickering screen that ended with the TV turning off. I replaced both invertor boards and the TV seemed to work fine for a few weeks. Now the TV works fine...


Good day sir Alfred!!!!

If your screen turns to back after a minutes but the sounds is normal..That problem is very common to all flat panel specially to LCD TV..

OK,I need to know first if your TV having a back-light when the picture went out after a minutes.If that so the possible problem is T-CON board (this board is the responsible to produce a video on all LCD TV)..

If you don't have back-light the problem is inverter board again..But before you order or install new inverter board try to find why the inverter board gone only on few weeks after you install it..the possible problem why the inverter board faulty for the short period of time is higher/lower input voltages (24vdc) comes from power supply..try to check it using volt meter or multimeter tester..it should be read 24vdc on meter..let me know if the voltage drop or higher to 24..

If the 24vdc is fine the only problem is the condition of inverter board maybe its used or partially faulty when you buy it..

if you have more queries and clarification regarding my solution please feel free to reply on this tread...

Hope it helps..

Thanks for using fixya..

37 Vizio shtting down at random


Can you list the modules that were replaced thus far without resolving the problem? Also, what exactly is the problem? Does the set work sometimes and not others?

Thanks,
Dan

Vizio shuts itself off


There may be some components failing in the power supply or one of the circuit boards that are causing too high a current pull.

I realize that this answer is very vague. Without doing proper diagnostics, it is impossible to guess at something like this.

Out of warranty repairs on these sets can be very expensive. I would suggest that if the set is going to be expensive to service, it would be best to replace it with a known brand name that offers an extended warranty with local service. You will pay more, but you will have dependability and better quality.

Vizio LCD 37 Inch Turns Off Randomly


I had a similar problem with my 32 inch plasma tv. I called vizio's
1 800 number and the guy said to unplug the tv from the wall and hold down the power button for a minute and then plug the tv back in outlet and turn on. And it works I guess from what I understood from his heavy accent was that the tv retains power and this resets it somehow. hope that was helpfull!!
