I connected my 8310 to a multi-voltage in-car voltage converter set to 4.5v but the polarity was wrong. The phone still works but won't charge any more. Swapped out charging block and battery from known working 8310 but no difference. Obviously something has blown in the charging circuit.
Anyone have an idea of what to do to effect a repair cheaply?
TIA,
Geoff. :cry:
