More then likey you have a bad mainboard. Especially for the 32inch and below its usally the mainboard rather then the powerboard.
The tv parts are modular you can usally buy parts on ebay. I dont recomend soldering or anything like that, just a simple board swap will do.

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. Or, it maybe something simple like a blown fuse inside the TV. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptom.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

Vizio TV wont turn on after three weeks no use


My vizio recently did the same exact thing. Vizio sent an HDTV tech out to fix it and it was the power board. He put a new board in (took 15 min) and the tv works like new.

No picture at all. had no problems until last night, turned TV on, and no picture. TV is VIZIO 32 inch LCD


Do you still get sound? If you do get sound, then the problem can be in the backlight inverter board or in the main power supply that supply 24vdc to the inverter board.

The power went off a couple nights ago now my vizio 32 inch plasma tv wont turn on at all nothing this happened one other time and someone else held down the power button after 3 days and it finally turned...


Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

32" VIZIO PROBLEMS


The main board is bad. I have seen a lot of TV has the same problem like you have. Replace main board will fix it. If you bought these TV from Costco and less than 2 years then they all still under warranty.

No Power to a Vizio VX32L


My best guess is to check for blown fuses or the power board when bad inside the TV.
If that doesn't work, looks like you'll have to pay a repair shop to find out what's really going on.
Sorry I can't help you further.
