Most have a fuse in side other than that off to the repair man, get a quote as it could cost a lot.

For the 46" TV, it sounds like the main board is bad.

For the 50" Vizio: is the LED light on?

SOURCE: vizio glv47 powers up no then no picture

We have the same problem and purchased a power supply to see if it would fix the problem. It didn't. We are now in the process of buying the main logic board and we will let you know if this fixes the problem. It seems like it is in sleep mode but doing the steps to get the tv out of sleep mode does not work.

SOURCE: My Vizio VX32L LCD TV will power on but no picture or sound

I had the same problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound.

HOW I FIXED MINE: I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine. I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.

Vizio e420vse doesn't power on when plugged in. Is this a power supply issue, a main board issue or LED driver issue?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

How to fix tv turn off by itself


If the TV turns off by itself during working, there must be some fault with its main power regulator board inside. Check it. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.

VIZIO VS470 WON'T TURN ON


do you mean the power indicator at the front panel doesn't light.ok this kind of trouble is in power supply section since the stand by doesn't work. the first place to be check is the fuse if blown. if blown with darkened color that was an indication that has other component part that get shorted. at this time you will need a proper trouble shooting using the a device like a digital or analog tester. if you don't have enough idea on how to do the job and necessary tools, just send it to the trusted service shop to fix the problem.thanks for using the fixya.

Pluged up but wont come on


Does power indicator lit if tv plugs in?
This will confirm that power outlet is fine and tv getting power through ac cord.
Does power indicator blinks?
If it is blinking that means tv got some internal circuit problem that could be defective power supply board or bad back light inverter board.
Visual check by local tv repair shop would be good to rectify what board need to be replaced to fix the problem.

HERE'S THE FIX: I just went through this with my Vizio VX37L. TV is stuck in RGB input. This is the fix.... TV is stuck in RGB input.
(option 1) Power on TV, and press the INPUT button repeatedly and rapidly until you can change to a different input, such as AV.
If that doesn't work, try:
(option 2) With the TV off, press and hold the INPUT button on the side of the TV for about 5 seconds. The TV should power on and the input list will appear. The TV will no longer be locked, and the INPUT button should function properly after that.

Option 2 worked for me!
