I own a Mitsubishi 27" TV that I bought when I was 16 back in 96. This TV has been great and still works like a champ. It even survived falling off a couch! However I have started to notice horizontal lines faintly in the background. You can only notice them on a completely black screen. What exactly is happening? I've seen this before on a old Sears brand TV. It usually means that its on its last legs. Is this something that I should be concerned with? It doesn't seem that a TV that is only 6 years old and especially a Mits. should be doing this. I want to get a HDTV Widescreen, but I'm not exactly ready to do it now.
