So I have an older receiver that is acting up. it takes forever for it to change channels you get a blank black screen then it changes the channel. the caller ID quit working I tried to force a firm ware update and all it does is hang. it goes super slow gets to about 58% and shuts down turn it back on and it picks up and then starts over again. this was going on for about 3 hours today I just gave up unplugged it let it sit and plugged it back in and it works just sloooowwww under setting looks like it has not had any kind of update since April of this year....
