Customer called directv because she was having problems with the picture messing up at times. Two techs came out, replaced the LNB, ran new wire to the house, replaced the SWM splitter and power supply, and the DVR. Then, last night she had another "glitch" that she described as a 3" horizontal bar that goes across about a third of the width of the screen. And the DVR recorded this "glitch".

Any ideas what is causing this?

So they have pretty much replaced everything except the actual box at this point?

Is this the only receiver in the house?

We had a client with an issue last week, and my tech also had an issue.

I think they may have had a problem on the AT&T side of things.

He said they did replace the box (DVR).

Questions:
Do they have neighbors? How far away?
Does it happen around certain times of the day?
Where is the dish mounted? What is near the dish?


My 1st thought goes back to a couple of installs many years ago. When a radar detector sitting on the dash of a car, was causing the signal on the dish to screw up. In one case, it was the neighbors car - about 60 feet away from the dish. In another case it was the owner's car, parked about 80-90 feet from the dish.
I wouldn't think any of those 'old' radar detectors are still around - there was regulation decades ago, that said 'new' radar detectors had to be built with no detectable emissions. Which wasn't that hard as many companies had already started building them, due to states with laws against them using radar detector detectors.
The point being, good possibility it is a rouge electronic device causing the issue. Remember the thread a year or 2 ago about the garage door opener, that was causing a CCTV camera location not to work. Crazy.

Years ago a client who used channel 17 for analog distribution of an SD DirecTV's signal lost the signal.

I smacked his mind into a research frame of mind and he realized it happened starting at 7:10 PM every night. Further thought led him to notice that outdoor lights came on at that time. Poking around, he heard a PAR lamp that was buzzing. He took the lamp out and the problem was solved.

Think this stuff doesn't happen? Think again!

My gf likes to watch pretty much the same channel, backing up the news shows so she can skip through the ads and the repetitive weather reports. Yesterday the screen went black for a half second, then the image came back.

It was playing at the present time and she could not back it up. It was as though it had been changed away from the channel, then back to it. (If you shut the receiver off, you can still back up on the same channel when you turn it back on.)

So we're watching to see if that's the first death knell.

The dish is on a pole, probably about a 75' run from the house (cant run the wire straight, it has to run an L shape, up and over). Its tucked behind some shrubs, but the DTV techs pruned the shrubs way back. I did wonder if they thought to scope up higher and see if a hanging tree might affect the signal. Also, I havent been back to check the signal. Often the DTV guys get in a hurry, dial in the first three birds, which around here puts the HD sats in the high 70's. Plenty of signal to work in fair weather.

The client claims that other TVs dont have a problem. But this is also the only DVR. Getting her to go into a research frame of mind would be harder than to get Bruce to vote for Trump. It just aint happening. So I have no idea of how to narrow down if something else happened around the same time.

I have a customer with the same issue:
Every morning he turns on CNBC, it will not play the live version, only starting from like an hour prior to him even turning on. It's not even set to record. It is a client on a Genie system. Through some combination of powering off/changing channels, he can eventually get it to LIVE mode.

I discussed this with my local DTV installer, he had no idea what it can be.

Brian,
your client's issue is not at all the same. Ours will always play live.

Normally, in the morning we can turn on the receiver and the TV and back up the reception the normal 90 minutes. This is almost the reverse of what you describe.

Sometimes it's not on the channel we left it on, even if nothing has recorded overnight. We've set it to record at 6 AM for five minutes on the channel we want it to be on, but when we get up at 8 it's not on that channel.

I've asked here if anyone knows how to force the receiver to be on a particular channel first thing after being off for many hours. The best solution was to record for several hours so we capture what we're trying to be able to see.

Ugh weird one I have not seen but marginal signal or one out of four LNB leads are bad can cause some weird behavior even on just one TV. I think of 70s as being pretty low.

Maybe it's an electrical component is going out in the TV and the DVR captured it. Either that or you need to adjust tracking.

Minimum acceptable signal is 84. 70s will definitely give you issues. If you were installing this new, the box wouldn't even allow you to activate with signal below 84. I can't say that this is the ONLY problem, but it's definitely A problem. Since the dish is on a pole, you could check and make sure the pole does not spin. If it does, that's probably what's causing it. If the pole is solid, the dish could be either out of alignment, or clipping a tree.
