I recently did a repair to a 48GX by shoring up the rubber pad which supports the contact strip connecting the keyboard to the PCB. The calc now passes the keyboard test and the self test. However, it now will not beep during testing. The spring is firmly soldered in place, and makes contact with the disc. Any ideas what else it could be? Thanks.
