Hi,

You can always try to reset the phone. Nothing ventured, nothing gained.
To reset the phone please long press the OK button (>10 sec), the phone will ask if you want to reset, then select OK or login to the phone and perform from there a reset. (On T48G, Settings > Upgrade > Reset)

I really don’t know if it is worth to repair it, it depend on what is wrong with it. Human labor is expensive. Maybe a new phone is cheaper.
Is there still warranty on the phone?
