You didn't say, but I'm guessing it's a 17" iMac. That particular form factor is notorious for LCD failure, which begins with one row of stuck pixels and progresses to the point where there are so many rows they can't be counted, and often whole chunks of white screen. In other words, your LCD is headed southward like untold numbers of others.
If it's a 20" iMac, it could be the video card or the LCD, but more likely the LCD if the external monitor's OK.
Think about how many times you've seen a LEM Swap member looking for a good LCD for a 17" Intel iMac, then check the going price for a used one on eBay (@$200), if you doubt me. Been there, done that.

Uh, yes, if you can't stand seeing that single line. It may take a while for more lines to appear, or the degradation may happen more quickly. About all you can do is use a second screen as the rest of the iMac itself will continue to work perfectly. On the other hand, I was asked recently to refurb two early-2006 17" Intel iMacs. They have perfect LCDs, but bad logic boards. Fortunately, because of the 17" iMac Bad Screen Plague, it's much, much less costly to replace a logic board than an LCD.
As I said, been there, done all of that.

Here's an alternative to throwing out a good Mac, HiRez screens too.

For $160 this seems a fine answer... fun project and I don;t throw
the useful thing out ... except the old dead screen... (maybe I'll
mail it back to Apple...!)
