Analogue-sequencer

Hi!
I think my LCD has some problems.
It's going everyday darker:
when i turn it on i can't see all the characters,
and only after 5-10 minutes it becomes a little brighter.
What could it be?
It's an hardware problem or do you suggest to reinstall the software?
Thanks for any help...i'm really worried because I can't live without my
P3!!!
