I don't like getting the shaft. I have the protection plan so it didn't cost me anything extra. I am in Georgia so it doesn't get that cold here. It has happened when it was 20 degrees or like last night when it was 50 degrees. When it happens it happens on all of the receivers but not all at the "exact" same time. For example the den may go out for 5 or 10 seconds and then a few minutes later the office may go out. I don't honestly know if any of them have ever gone out at the exact same time. It seems to happen on all of the channels. Last night I had the receiver in the kitchen on and it went out for a few seconds. I had it on TV Land (304). When it came back Family Fued with Steve Harvey was on, and it had the Game Show Network (233) logo on the screen. I thought it must have changed channels, but when I pressed info it was still on TV Land. I pressed channel up and back down and it was back on TV Land. This happened earlier in the week on a different receiver as well right after it went out. So far it hasn't gone back out. I hope this will resolve it. I saw another post here from a guy that had the same problem and a new power inverter solved his problem. If it goes back all I know to do at this point is call them back and have them come back out. Any suggestions? I am open to any and all ideas here. I am addicted to tv. I will admit it!

That's a good clue and reinforces what we are suggesting. Just to give you an idea how things work. Let's take satellite 101. The satellite has two sets of transponders, odds and evens. To switch between them, the tuner puts a voltage on the cable. 13v for odd transponders, 18v for evens. What you were seeing is the dish delivering an odd numbered transponder instead of an even one. The receiver thinks it's getting the even transponder (so the channel banner is correct) but the picture is from the corresponding channel on the odd transponder. And if there is no corresponding channel on the odd transponder, you will see a 771. This can be caused by: A fault in the SWM16 A fault at the dish A cable/connector issue (by far the most likely) So we're no better off in knowing which of these is the problem, but it's almost definitely one of them. A suggestion. Go to the SWM 16 and check the cables/connectors that are connected to the two connectors on the SWM16 marked "18v". You might find that one of these is faulty. Make sure all the connectors are tight. Also check the connectors (all four of them)outside the house on the grounding block, that's where corrosion often occurs. If the dish is within reach, check the connectors at the dish. If you still can't find the problem, get DirecTv back in. Make sure the service guy checks all the connectors at the SWM16, at the grounding block and at the dish. Ideally persuade him to change the SWM16 and the LNB at the dish, since you can't be certain the problem is not in one of these pieces of equipment, and there's no way to be certain except by replacement.
