I would open it up and see if there is some spilled fliud under the lip of the bezel.
May not be, and as RTI said was dropped. We have a client that had phantom button presses and we found soda under the lip and the stickiness of it was causing random button presses when the remote was used...not sure how it was happening but after we opened it found the spilt soda and cleaned it all was fine
There's no worse feeling than that millisecond you're sure you are going to die after leaning your chair back a little too far.
