Alpine car stereo (9851)

Hi there,

My Alpine 9851 keeps switching off while playing, then either comes back within a few seconds to the same track or stays off for a few mins and completely resets itself. I have checked that none of the wires are loose.

The only thing which i can think of is the case has become slightly bent due to somebody trying to steal it from my car. Could the fact that the stereo is not mounted perfectly straight be the cause of this?

I would appreciate it if anybody who may know what could be causing this could let me know.

Many thanks
