Sony Str-k750p Automatically Switches To Video 2

My Sony STR-K750P automatically switches to Video 2.  I select a different input, DVD, Video 1, CD, etc, but within 3 minutes, it will switch back to Video 2. It might take 10 seconds or it might take 3 minutes, but it always switches back to Video 2.  I have my Sony KDS-55A2000 TV and a Comcast Scientific American cable box hooked up and a DVD player hooked up to the receiver.  I've tried to use RCA cables and optical on Video 2 to see if that made a difference.  I've also put my DVD player on Video 2 input instead of my cable box, but no matter what I do, it's the same story, it switches back to Video 2.  Has anyone else had an issue like this before?

you probably just have a problem with a video 2 leaky tact switch needing part replacement, it's like you always pushing on the switch continuously
