Signed up with Dish in July. Have a 722k on one end of the house, TV2 is on the other end of the house and through 4 walls. Had to make a patch cable and get the antenna up in the air a little to make it work, but once I did that, it's worked flawlessly all this time. Until this week. One night we go to watch TV in the bedroom and get nothing. Assumed batteries were going, so got a fresh set. Same thing. Figured the remote's UHF transmitter went bad, but to prove it I borrowed the remote from our 222k and paired it with the 722k. Still couldn't get it to work. So then I figured it had to be a problem with the antenna or patch cable. So I borrowed the antenna from the 222k and reterminated both ends of the patch cable. Still nothing. If I'm in the same room as the 722k, it works, even with the IR covered up, so the remote is broadcasting UHF and the 722k is picking it up. But if I go just 15 feet away and around the corner into the kitchen, it gets flaky. A couple more steps and it's done. For it to be working fine across the house for months and then suddenly not be able to work from the next room, and with everything external to the box being ruled out, I don't see how it could be anything other than the box. I tried a hard reset as a last resort... I didn't expect it to work, and it didn't. Has anyone else ever experienced this?
