I have a 42" Vizio LCD tv ,the touch pad on the front won't do anything and the remote will not turn on the tv. The tv turned to a blank screen when we were watching it. I tried the remote, it didn't change the screen just stayed grey blank. I unpluged the tv and pluged it back in and tried the remote. Tv will not turn on. Any suggestions ?
Sounds like a fuse and/or Circuit board components have failed. Would not suggest atempting repair unless you are familiar with electronics and the hazards associated with repairing such equipment. Can do damage to yourself or further damage to the equipment.

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?
SOURCE: no picture or sound, light comes on in the front and have to unplug tv to turn it off.
I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

I had a similar 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. I didnt hear an arcing sound though.
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. I would check the ceramic fuse first on the board that gets power from the plug.
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.
SOURCE: Vizio 42 in TV LCD HDTV white line across to of
That white line (usually jagged) is actuallly part of the transmitted picture. However, you are not intended to see it because it is located in what is known as the 5% overscan area. Your TVs today are more than just cable ready... they are a versital, technology filled multimedia display. You can see that line because the screen size or wide mode you are using is intended for 1080p/24 signals. You have 0% overscan with this screen size setting. This allows you to see ALL of the picture, including portions of the picture the broadcaster did not intend for you to see. You can change your screen size using the Wide feature in the Setup menu. See pg.62 of your user manual for details and descriptions of the various wide modes.

I have the same problem!
TV just shut off. No power. The amber light and the green power light are not lit. TV power button doesn't work nor does the remote. I am 90 days out of warranty and VIZIO wants $415 to fix
We were watching Nancy Grace,and we stepped outside for a few moments,when we stepped back in our t.v.was blank, gray screen,and we could not use the remote to turn it off. we unplugged it from the outlet,and then we plugged it back in, the t.v. was off, but the remote would not turn it on. Now this is may 12-2009, we bought this Vizio 42 in. t.v. at Wal-Mart, here in Sallisaw Okla. on apr-15 2008. Oh! my, it lasted long enough for the waranty to run out!!!! We paid 898. dollars for this contraption!!! and bought the wall-mount as well. Can someone please help us? we don't know what to do. We are on a fixed income,and we sure can't buy a new one-----Everyone Beware, of these stinkin' VIZIO'S I wouldn't have another one. Helen, From Oklahoma!!!!
