OK, so my HT isn't the greatest, but I need a little help. I have a small refrigerator in the same room as my HT. When the fridge's cycle ends, I get a small flicker on my screen. I have the TV (and the rest of the HT) plugged into a surge protector. Is there anything I could route the HT through to remove this regularly-occurring flicker? I was thinking a UPS, but not sure if that would work.
