SOURCE: Vizio GV42L LCD TV screen black when turn TV on first time

If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.

SOURCE: red bar/green bar on left side of vizio plasma

POSSIBLE solution:
We have the same problem on our 42" Vizio plasma screen. I've had many conversations with the tech at Vizio, and they said it's an inherent problem with the screen (whatever that means) that can't be fixed, or is not worth fixing (as another comment says).

But...when a cable guy came to install a new dish, I told him about it, and he said he's seen it before on other plasmas, and that it may be caused by the sound speakers being placed either too near or in the wrong position near the tv.

He said there are magnets in the speakers that will throw off something in the screen.

We have a Bose sound system, and so we tried repositioning the speakers and subwoofer. The line did go away, but then came back. It comes and goes.

Who can figure this out? Well, for what it's worth, try repositioning your sound speakers.

SOURCE: Picture but no sound on my Vizio L37 Flat Screen

I had the same thing just happen and I used the following instructions from the Vizio Website for "humming sound" on tv and it worked. My sound is now working!!!!

1- Power off TV

2- Unplug TV from outlet

3- Press and hold in the power button on the TV for 30 seconds (while it is unplugged from the wall)

4- Release the power button

5- Plug in the TV into a different outlet

6- Power the TV back on.

Reset the TV settings.

Start by testing the voltages coming off the power board. Cycling is sometimes an inverter board or a fluorescent tube or a connection to a fluorescent tube.

My Vizio TV has a damaged display can this be fixed?


It's not a difficult repair, however, it will likely require a new LCD panel. I'm unsure how feasible it would be to order a replacement panel, but it might be worth speaking to a local repair tech (who may have a salvage panel) or searching Craigslist for an identical model in need of repair, but has an LCD panel that is intact. Personally, I've found that, unless the display panel shows physical damage (such as yours), it works well as a replacement part.

Sounds like you either have a faulty LCD panel tab, failed LCD driver board, LCD/t-con panel bad connection, or a bad t-con. You will need to get a diagnoses to be sure.

Unplug the TV from the wall. There must be something wrong with your circuit board. Call customer service for what to do to fix your TV or get a new one.

Picture is frozen onto the screen. Tried powering off tv and cable box that did not work. Next unplugged TV and that did not work


Sounds like a burn in, this is common when some still image is left on the tv screen for sometime, the only hope is to get to a white screen or static screen and let set for awhile, like the old days when you didn't have cable or any input and the tv just frowns.
