Since installing Fios this week (Motorola HD DVR STB) our Samsung TV shuts itself off about every 1-2 minutes. I noticed this definitely occurred whenever several of the remote buttons were pressed, but then I removed the batteries from the remote right after turning on the TV and it continues to occur! Any ideas? The TV is NOT plugged into the STB box, and I tried unplugging the TV and plugging it back in, to no avail. Help!!!!
