problem with palm tungsten T3

Hi,
I have been having a very serious problem with my T3 (I know, it's an older palm) and was wondering if anyone knows what I can do about it. It turns on but nothing works right. For instance if I try to list my contacts I end up drawing lines. If I get into the contacts, the stylus seems to quit working and I can't navigate. Nothing is working as it should. I have tried to re-start it numerous times but the problem persists. I'm guessing I need a new palm but thought I would try you folks first. Is there anywhere I can have this unit restored?
Thanks for any help.
