Last night, I was attempting to watch TV through my Genie (or Hannah Davis if you wish to get exact), and experienced a weird issue. When I turned on the unit, the screen was blank. Then the picture would come through, but it pixelated at times or would freeze. Then, I would change the channel from 206 to 209, and the NHL Network would appear for a moment, then the screen would go blank again. Then I would change to 501, and a Lifetime channel would appear. I began troubleshooting with a CSR last night with no success. Then about an hour later, everything began working as normal. So far this morning, everything is working as expected. Any thoughts on why this occurred, and should I expect this again?
