Screen glitches in and out
We got a new TV a month ago. Unplugged the old one, plugged in the new one, no problem. Then the screen started to "glitch" - it goes to black for a couple of seconds, then resumes. Sometimes it happens once or twice a day, other times (like now) it happens every few minutes or even less than a minute apart. Comcast phone support was useless due to language barrier (twice). We unplugged the entire setup, let the modem and router sit for a while, and hooked it all back up. That seemed to solve it, but a few days later it started again. This happens no matter what we're watching: network TV, cable (all channels), any app - Netflix, Prime, YouTube - all of them. Driving us crazy!
