Electrical Interfence with Signal

    This is my first post. I have a DirectTV HD receiver with recessed lights recently installed in the same family room. After I turn on my recessed lights, the receiver loses the signal.

    After I turn off the the signal returns. It only happens to HD channels when I get the interference and error code 771. Is power to the lights causing electrical interference?

    As anyone experienced this problem? I want to isolate the problem before calling direct tv.

    Any advice appreciated.

    Typically a symptom of poor electrical ground, either with your lights or your DirecTV satellite cables. You really should have a qualified electrician take a look. This can be very difficult to troubleshoot yourself.

    What model HD Receiver do you have?
    Do you have other Receivers/DVRs? Are they affected also?

    could be bad F-connectors or damaged coax's shield somewhere, especially if it done inside of walls

    The one HD receiver in the family room where the recessed lights are located is model H23-600. When the lights are on downstairs my HD/DVR upstairs also gets interference with model HR23-700. Same issue, when the recessed lights are on then both receivers lose signal intermittently. I saw somewhere where someone said to change the dimmer switch to a higher capacity /wattage rating. I haven't tried that one yet.

    Is that a DirectTV installation problem or my contractor?

    Honestly it sounds like an electrical problem if it never occurs when the lights are off. You are not using fluorescent lights by chance either are you?

    No, these are recessed LED lights on a dimmer switch.

    I'd be looking at that dimmer. When fluorescent lights became available that could be used with a dimmer we had all kinds of problems at the place I worked at.

    Why don't you do this: Take out the dimmer and put in a normal wall switch. That will answer any questions regarding the dimmer. If the problem goes away, you'll have to look for a different type of dimmer that won't interfere with the receiver. If I were you, that would be the first thing I'd do.

    Thanks all. I'll try changing the dimmer first and report back.

    If it is your dimmer switch causing the issue, we just installed the Lutron Maestro from Lowe's in our house, and it works just fine with our can lights and HR44.

    The remote control is really handy, too! My wife thought it was completely overkill, but after using it, she is sold on it!

    Great idea to narrow the issue.

    Another way to troubleshoot, at least for wiring issues is to run the power to the dvr into a room with a different circuit than your cans use.

    The way my house is wired (I didn't do it), it might still be the same circuit. But an extension cord to a known different circuit would still be easier than installing a switch. I do believe that I'd try that first. Either way, I think he'll find the dimmer is the problem. I really doubt it's a grounding problem. Shouldn't be an overloaded circuit problem either. I dunno, it's hard to troubleshoot without laying hands and eyes on the problem. Could be a loose neutral, who knows?

    Please remember contractors will ALWAYS use the cheapest product unless you select and pay for a better product.
