Why is my back light so dim?

Why is my back light so dim?
Ive had this iPod for very long so that means i have no warranty and I don't know what to do becuase I always need a current light around to be able to see the screen. Please help me. i have no money to afford another.

Guides to replacing any part of the iPod will depend on what model you have. Try to identify it using Apples Identify Your iPod page."
