We suffer frequent (but short) power outages so I bought a few UPS's (uninterruptible power supplies), mainly for lights, but I figured I could run our 13" kitchen TV for a while off of one too. When I test it, I plug the TV into the ups & then unplug the ups from the wall, the TV still worked fine. (I even turned the TV off & back on just on the ups's battery) I leave the TV plugged into the ups which is fully charged. Now for the kicker: When we have had an actual power failure the TV will not work off the ups's battery????........I get an intermittent picture & then blue screen which seems to cycle about every second!! How is this possible?
