I purchased a Vizio VO22L LCD TV from Costco about 9 months ago. It is connected to Comcast through a coax cable from the outside, and I do not have a cable box. About 2-3 times per day the TV crashes. with a picture frozen, no sound and none of the buttons work. I have to unplug and plug back in the TV in order to clear the fault. I have called both Vizio and Costco and they are stumped. I have also heard there may be a problem with the signal coming from Comcast overloading the video processor. It only happens when watching digital channels. This does not happen when watching the analog channels. Anyone know how to fix this?
