    I have 42 inch LG Plasma. I have the same problem. A red bar is appearing from top to bottom on the left hand side about 1 1/2 inches. The red bar in small than the black bar that you see on non-HD stations. Do I have to trash it after only a couple years.

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.

I have the similar problem on my screen before too. After restart my PC, it disappear.

I think you can identify your problem is monitor or display card problem by taking a Print screen, and plaste it on a word document. If it appear the screenshot having a same line, then it would be the display card problem. Otherwise, you can change another monitor.

I also have a Vizio 42" Plasma [P42hd] with the same problem a 1" thick red line vertically on the left side; which comes and goes. Which started about two weeks ago on some days its there for the whole day and other days it doesn't even show.
I brought this set back in March of 2005 at Costco for $2,000 and of course the warranty is expired, now! I contacted Vizio Inc. which they transfered my call to a off site service tech center, who told me that this model is no longer being serviced by them do to parts (he didn't get into detail) and so my situation will be referred back to Vizio and I should hear from them soon....One week now & I haven't heard from them yet...I guess I'll call back!

Red line on screen

The vertical line, in my case, was due to a bad contact on the flexible printed circuit. I fixed the problem by using a piece of a rubber eraser to apply downward pressure on the flexible circuit as shown in the picture. To locate the faulty section lightly push on the flexible circuit from lef to right untill the line dissapears. 9f78570.jpg
