Help! Pre amp turning on by itself.

 Yes, that's my problem. In the last month I have found my pre amp powered up for no reason. Just me and wife home, no one else in house. No pattern or consistency as to when I might find it on. Nothing has changed to system, nothing new added, there is no TV in room. Im wondering if this could be turned on by something remotely, or is the switch failing in some way? Going to reach out to Modwright also, but would appreciate any thoughts . TIA

Cover the unit's IR sensor.   That will rule out external poltergeist.

If it is external blocking the IR sensor should help confirm.

Does it turn itself on if you plug it in?   Meaning first time it receives power at it's AC in, does it turn on?   Like a TV does if left on a switched outlet ?

If so, you may be loosing power at the conditioner for a split second.  

All I can think of is a condition like that or extraneous light of a certain wavelength. 

You can test the remote to see if a button sticks by holding the IR  in front of a Samsung Tab camera or Samsung phone camera.  Most will show the IR as a purple light when in the camera mode.
