* Discharged battery and battery corrosion
* Case corrosion and rust
* Bad volume adjustment slider

The unusual white plastic connectors on the motherboard are called "Wire Trap Connectors", and they are easy to both remove and reinstall. You must simply push downwards on the middle part of the connector (basically, the plastic immediately surrounding the cable) - this unclamps the cable, and it can be pulled out with almost no force! The reverse is exactly the same - push the middle part downwards, hold it there, insert the cable and release. The insertion also should take no force when the middle is pressed down correctly.
