Walter,
You have a TV on a UPS? Why would you do that?
I suspect you are not talking about "uninterrupted power supply",  
but rather about a "surge protector".

Typically, many devices die not when the power goes down, but rather
when it comes back up. At that point, all the equipment starts at once,
and there is a large inrush current in the circuits.
Most electronic devices are prone to that.

Usual precaution for the devices that cannot be plugged into a surge
protector or UPS, is to unplug them when the outage occurs.
Many computers, controllers, etc. are lost that way in research labs.
