iPOD CLASSIC SCREEN IS DIM, CANNOT BRIGHTEN

Hello there,
It is hard to say at this point. A toss up you might say. Could be the backlight itself or just a bad connection. And it also sounds like you have done your part in trying to diagnose and repair the problem with what solutions are available. If you still have a warranty, I would recommend taking full advantage of it. Otherwise, I think your best bet would be to send it into a third party repair service to have them diagnose the exact problem as well as repairing the device if you wished so.

There are numerous third party businesses out there who offer repair jobs for iPods as well as diagnostics tests (some even for free) for the iPod. Just do a simple google search for "ipod repair parts" and you should receive a plethora of sites that can help you. I would also recommend doing a little bit of shopping around research to find the most affordable and qualifying deal. 😉

Here are a few:

[KingiPod|http://www.kingipod.com>

[ifixit|www.ifixit.com] is a website that offers replacment parts as well as excellent step-by-step instructions on how to replace the part yourself.

Hope this helps.
