This seems to point to a faulty I/O board where you have power input and part of audio circuitry. First thing you may want to try it’s a replacement, board and relevant connecting flat cable are relatively cheap and the job may be done on a DIY basis too. Don’t forget to disconnect battery before working on the board. Here you find a guide to help you with the job:
