Red line down right side of screen

have almost the same problem left side is black with sometime blue line red lines or a whole bunch of different lines some one help please have sound and right side of tv works fine

Ur backlight inverter video board is dying.
Need a new one.

try plugging in other sources like a dvd player, connect it on different channels. if they are always there you might need a new tv.

You will need to replace the control board and your TV will be better that a new one.

The panel is almost certainly bad. The only fix for this is to replace the whole panel which would cost more than the whole TV.

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.

I had the same problem -red, vertical bars along the right side of my Samsung 42" Plasma- and this is what fixed it: Removed unterminated cable.  
I had hooked up an HD video camera to the set about two weeks ago.  While I disconnected the camera I left the other end of the connector cable plugged into the T.V..  As I've since learned from friends who work in television, this is what's called an "unterminated cable" -meaning one end is unconnected.  It can lead to problems with electrical interference and appears to have been the problem in this case;  When I disconnected this cable from the T.V. the red bars went away.
So, check your cables.  Make sure everything is properly connected and get rid of anything that might be picking up interference.  
Hope this makes sense.
