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.

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.

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.
