Dead/Stuck pixels on camera screen?

I have an Olympus X43, bought about 2 years ago (so no warranty), with a significant area of pixel damage to the LCD screen. It doesn't affect the pictures at all, but I am looking into selling this to get an upgrade, and I was wondering how much impact this would have? The area isn't uniform at all, about 15mm long and varying up to about 6mm high. Where would be the best place to try and sell this as well?
