OK...so I posted not too long ago about service going out every time it rains. Haven't had any problems with that lately that I'm aware of and things have been working really well, but now we have something new going on. Not sure exactly when it started happening. We were out of town, came back late Friday evening, and first started noticing the new issue Sunday evening. We have the HR34 Home Media Center in the living room, and two H25 HD receivers (one in each bedroom).
We're having random issues with picture and sound freezing up/going out. Each time it happens it lasts for about 1 or 2 seconds, but it happens over and over and over...like we'll hear every other word when people are talking. Sometimes the picture will freeze at the same time, sometimes it won't and it's just the sound. Sometimes the picture just freezes then starts back up, sometimes it goes to a black screen and comes right back. I haven't noticed any pixellation...just the freezing/going out. One thing I've noticed is that it doesn't occur on all the TVs at the same time.
Sunday evening we were watching TV in the living room and everything was fine. Turned off everything in the living room, went upstairs to go to bed, turned on the TV up there, and the freezing/going out was happening there in the master bedroom on the same channel we were watching downstairs. Went to the other bedroom, turned on the other TV, put it on the same channel, and it was working with no problems while the master bedroom was still freezing/going out. Turned on the TV in the living room just a few minutes ago and it's freezing/going out. Went upstairs and both bedrooms are working with no problems on the same channel as the living room. The freezing/going out also occurs while watching recordings, and the same thing happens with recordings. Whatever receiver is affected with the freezing/going out on live TV has freezing/going out on recordings, but we can go to another room and watch the recording with no issues.
I've tried doing resets on the affected receiver while this is going on (using the menu, pressing the red reset button, and by disconnecting power), and the resets never seem to help. I've gone into diagnostics on the HR34 when the problem is occurring and run the various diagnostics and everything checked out OK. Found information somewhere about clearing the NVRAM on the HR34, did that while the problem was occurring, and that didn't help. When it's occurring it does it on all channels (HD, non-HD, local) and (as already mentioned) on all recordings. I haven't seen it happen on more than one receiver at a time. It'll go on for quite a while, and then for no apparent reason it goes away and everything starts working great.
Any suggestions for anything else I can check before I contact DIRECTV? If they send someone out here it probably won't be going on when they get here, and they'll probably say they couldn't find anything wrong.
One more thing...also have the AM21 off air tuner connected to the HR34. Just checked and the freezing/going out is also occurring on OTA channels that are coming in through the AM21.
