Recently, my 24" iMac (which I received in Jan at the start of this year, but it's a 2008 model) has started developing some pretty annoying (and pretty bad) screen anomalies: namely, a huge black horizontal 'scanline' near the bottom of the screen. It seems to be caused by backlight unevenness, and is only visible on solid colours, but I'd say it's a bad case of it, especially since it isn't confined to the corners, and isn't symmetrical (closer to left of the screen, so on solid white etc. it looks like a giant black smear) I'm well inside of my 1 year warranty, and I'm contemplating getting the panel replaced (or the entire machine if I can make enough fuss + show that >1 component is at fault etc.). The thing is, it's a lot of bother (in terms of inconvenience) and by the looks of it, all the screen panels on every iMac really suck. They all have the same problem, although normally to a lesser extent than my current one. Whilst I wanted to fix this problem before my warranty ran out, I just wanted to know your thoughts on whether it is actually worth replacing - will the panel replacement actually fix the issue? Or am I going to end up with a complete waste of time due to no improvement etc.? Thanks.
