Futuretvowner,
Ive been brainstorming
![Clap :clap: :clap:](/i/s/clap.gif)
what could be the cause of the symptoms that your experiencing, ive narrowed it down so lets give it a shot to see if it helps you.
The nickel platting can develop an oxidation that isn't visible to the naked eye

, it mostly develops on the battery sleeve. An easy way to clean the oxidation off is to use Vinegar
![Can of worms :worms: :worms:](/i/s/worms.gif)
. Take a 50-50 mixture of water and vinegar and allow the main body and the battery sleeve to soak in it for 30 min or so

.
*Remove the batteries from the sleeve, and remove the interface/switch/core/cap from the main body*
Dry them off and reinstall them.
Let me know if that helps you.
Tim
