Long time reader to DBSTalk.com and first (or second?) time submitter. First, I want to thank all of the moderators and regulars helping the folks out here. Keep up the good work. Now, on to the issue. Two months ago I had the new HR44-700 and C31 client installed at the house. They replaced my HR21-200 and a newer HD receiver for which I can't remember the model number. Before the swap out my service was running just fine, minus the occasional thunderstorm. I should also add I'm a long time (13 years) DirecTV customer. The issue I'm experiencing on the new devices is that my channel blanks out and I'm getting a solid black screen on the TV connected the Genie and a solid white screen on the TV connected to the client. This started occurring a few weeks in and is happening almost on a daily basis. It appears to be signal loss but I'm not receiving any on-screen messages. If I press the Menu, Guide or Info buttons, those displays pop up just fine. To get my channel back, I just have to re-enter the number or use QuickTune. I have rebooted the devices a few times but the issue hasn't gone away. I have the Power Save feature on both devices set to Off. I have not replaced the HDMI cables because like I mentioned above, I was working just fine on the old equipment. As for the hardware, all I can say is that I have a Slimline-3 dish. The installer did have to go on to the roof and it appears he swapped out an LNB. Hopefully that is enough information. Any suggestions would be great. I suspect I'll need an installer back out to check the connections.
