Thanks for using FixYa.
A helpful tool for troubleshooting is a service manual.

One of two things are occurring with your Television. The first one may be silly, but I have seen it happen before.
1. Your next door neighbor has a remote set to the same frequency as yours, and it is causing things to happen with your TV when he/she is using their TV.
2. The only other thing this would be is an issue with the motherboard of the unit. I would have a TV Specialist take a look at it, or, if it is a recent purchase, return it for another model.

Switch between input sources can be caused by bad connection cable or by a faulty connected device. Try to rule out this connecting devices in different order and using different cables.
If you have other IR devices, as remotes etc move them to other rooms or remove batteries, to exclude this is a faulty remote.
If this is not cable problem, then random changing between input sources can be caused by a faulty IR remote receiver module on TV, the part Here is the spare: 6712000013A available for $5.
