I hate to open a cold case, but my less than 1 yr old MT2 started failing, and it appears to be heat related. When I first turn on my 722k, both OTA tuners work fine. I get 100% signal strength on several channels. After several hours my DVR gets very warm to the touch and the signal on OTA tuner 2 goes to zero on all channels. The signal on OTA tuner 1 stays at 100% on the same channels. The next day, starting cold, both tuners work fine. This isn't hard drive failure like the thread title, but OTA tuner failure.
I'm going to get a fan and see if things improve. If that fails, will Dish replace the MT2 since it's less than a year old (without the service plan), or will I have to buy a new one? If I have to by one, where do you guys find them so cheap? Dish website has them for $50, but I've seen many posts stating they're much less than that.
