Having been at the ex's this morning
she promptly kept telling me the TV just kept turning on all on it's own.
This was met with my usual eye rolling attitude (techno Luddite doesn't even come close), but sure enough it fired up while I was there.
Checked timers, nothing, turn on and then off timers
2 minutes later TV came on.
Then the age old idea came to me.
Grab the remotes (has two as the kids keep losing them)
Placed in kitchen
Problem solved.
Odds are it's just the batteries going in one of them and they are just going a bit nuts,.
