I live in an apartment bldg about 30-40yrs old. I've always noticed the electrical fluctuations and am now wondering if it's why I've had problems with my previous tv and now my one-yr old new one. I lost my picture last night on my RCA 25" F25649. The sound works fine. I've got it in a corner unit with plenty of airspace around it to prevent overheating. It's connected to my RCA receiver, a DVD player, and the VCR. I lost the picture a couple of times and reset it by unplugging the cable conx which I changed for a new one just in case it was a cable problem. I now have it correctly wired for my other components - did cable overkill and had too many plugged in. We had an ice storm yesterday and had a power failure. The tv was plugged into a good quality surge protector. All other components are fine. My computer monitor sometimes turns green after one of the building power surges and I have to reboot the computer to get the picture back. It occasionally freezes my DSL modem too. I'm wondering if there is any way to deal with this if the power fluctuations are partly the source of the problem. No tv until it's fixed - eek! I may be forced to clean.
