LCD problem with lines down the screen

[Hemi]

I have a 32" Advent brand LCD that I recently took out of the closet and started using again, only problem is when I turned it on I find it has a red line or a blue line from top to bottom. Sometimes the line is red and other times it's blue or sometimes it is a blend of both colors and it seems to depend on what color is on screen at the time. This LCD has just about every connection possible, from VGA to just about all types of RCA connections and a cable connection and I'd hate to let it get worse or dump it when other than this problem it is great.

I have a feeling this thing is just going to get worse and there is probably nothing I could do about it, but maybe someone can help.
