Question about Vizio 42 in. LCD TV
If I turn it off for a few seconds and then back on it fixes it for about 10-15 seconds. Recently my HDMI got fried with a power surge,even thought it's on a surge protector, so the cable one provider swithced my DVR to the old component 1 with all the color cords. I have checked all cords to verify they are in the correct place and full connected. Turned everything off completely, unplugged for a while and still no fix. Can someone please help me? Thank you and have a blessed day +
The box may be the issue----try unplugging it and wait a bit and power it back to let it boot up--same with the set.
Also if you have a DVD player look to see if it has this issue or not.

Old messages and bcipollina is gonna get to read this resonse twice; sorry-
If it just fails to turn on or ignores the remote, the main power supply is probably at fault and without some technical background and a couple of test instruments, you will not be able to do the repair yourself.
What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for a separate board with mostly larger components on it; it will have a ferrite core transformer on it and several larger capacitors which are cylindrical and mounted vertically to the board.
Before touching anything inside, especially on that board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.
If you see signs of overheating such as discoloration of the board material, it may not be repairable but if you can find a part number on the board, you might be able to buy the power supply and install it yourself.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload.
BTW, from what I have read about Vizio, I think they are close relatives to iLo which was also sold by Wal-Mart.
Quality control anyone?

Yes, I do in home warranty work on vizeo, it sounds like you need a power board and perhaps a main board. The power board is what pooped.

Is the HDMI port 2 work? Try to turn it off and turn it back on. If it is still not working then the HDMI ports have gone bad. You will need to replace the main board.

Well, your TV is still under warranty. That's the good part.
The only thing I can recommend without voiding the warranty is leaving the TV unplugged for 30min. That way, the TV can reset itself and hopefully correct the problem.
If that doesn't solve the problem, it's time to use the VIZIO warranty.
Here's contact info if you need it.

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:Look through the back vents for a white light to make sure the backlight still works. 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.
