Problem Since Installation

[Slaterman120]

Howdy


I recently moved from one house to another and had my DirecTV moved as well. I have had some serious 771 issues since the installation. After 6 sets of workers, 2 new LNB's and new wire the issue still persists. What is interesting about my issue is how the electrical is factoring into things. Here are two scenarios that I am dealing with. I welcome all feedback.

1. I have two HR21 boxes(main room and bedroom). If I want clear service (no 771) in the bedroom at night, I have to unplug the box in the main room. Once the box is unplugged, the service works perfectly. Once the main room box is plugged in, there are issues in the bedroom.

2. I have two sets of light swithces that when turned on, cause pixels and 771 in the bedroom. They are the hall light next to the bedroom and the bathroom light. In addition to the bedroom TV issue, the main room my flicker also when I do this

Another interesting point is that I added a heavy duty surge protector to the main room. The 771 issues that this TV was having have mainly gone away with that TV since I added this.
Any thoughts? Thanks for your help

Something pretty wrong there. I'm suspecting they drilled a hole to pass the directv coax and skimmed an electric wire in the wall or ceiling, then the exposed electric arced to the shield and burned it. Try this if you have a voltmeter. Disconnect the coax from the back of the receivers and turn on those light switches that cause pixellation and 771's. Measure with the voltmeter both to the center conductor and the metal screw on part that should be connected to the shield with the red while the voltmeter black is stuck in the ground hole of a wall outlet. See if you get any voltage at all.

If you do, shut off those lights and ask directv how they're going to pay your electrician to repair the damage.

Its also possible that when they ran the cable that they scraped the coax and hit an exposed ground line and the two are touching, making a ground loop in your system. The surge protector might either be stopping the ground loop or if you ran the coax through the surge protector, draining off some voltage on the cable shield.
