Most likely a new eec.

There is one remote possibility. On the circuit board in the eec are several (usually 3, I believe) capacitors. They have a tendency to fail with old age. It is slightly possible that this has happened and a failed capacitor has caused a short circuit to ground. They are cheap and easy to replace with basic soldering skills.

Picture. The bluish colored canisters standing up are the capacitors.
