Olympus XA Film Camera Not Working

The camera is near mint cosmetic conditions but has some issues:

1) The film counter does not reset and is stuck at E

2) The red plastic piece covering the shutter button falls off easily. One solution would be to glue it, and another solution is to not use it – the shutter button can still be pressed without it.

3) When set to battery check mode, the test light turns on but there’s no beep sound.
