Please, has anyone any idea why our upstairs tv's, change channel or turn themselves off, when any upstairs light switches are used?

it may be that the receptacle(s) are conrolled via a wall switch in your upstairs beds, quite commmon in fact.

Hello,
If you have a receptacle controlled by a switch, then the TV would be turned off if whenever you turned that switch to the off position. Somtimes these receptacles are split-wired so that only one-half of the receptacle is controlled by the switch. . .i.e. The top half of the duplex receptacle is controlled by the switch while the bottom half is always energized.

This however should not cause the TV's simply to change channels. And also, does this happen when ANY switch is used? (even a switch in another room or area)? If so, we may need some more information about your situation.

Cheers

Found a similiar situation where a flourescent light was on the same circuit as a mircowave causing the microwave to start all by itself when the kitchen flourescent light was operated.
Are your lites flourescent? Inductive kick from de-energizing the ballast could be cause the voltage surge to affect the TV.

Do you have wireless three way switches? You can tell by one switch from each pair will not be flush with the wall but will have a plastic box stuck on the wall. These switches will also switch the lights even if you just move the handle a bit without actually switching it. They use a radio frequency which can affect remote control TV.

Is it plausible or am I full of it? I'm not an expert on RF and my answer is based on basic knowledge and what I have read on the info packaged with wireless gadgets. If I'm wrong here please tell me. I'm always willing to learn (or unlearn!)
