I damaged this 5500 by connecting the wrong polarity to it. From what I've come across googling that subject it sounds like it might be made to work again by replacing some component of the charging circuitry. If you have another way of charging the battery it might turn on and work (I have no way to test that). In its current condition the battery does not charge and the device doesn't turn on. Perhaps someone would like it for parts?
Anyway, I have a new c3000 and have no desire to tinker with my old 5500. Therefore I am offering it to anyone who might want to pay the shipping cost from Arizona. I don't have the original Sharp wall charger, or a working battery, or a stylus. The screen looks good though.
