    Got a new install on Friday with two HR24 HD DVRs and one H24 HD receiver. The installer ran a phone line to the DVR in our family room, but the caller ID hasn't worked at all. I also noticed that our home phone line has static since the install. I did some testing and found the following....

    1. When the phone line is plugged into the DVR, there is static on my phone line when I pick up the phone. Unplug it, and the static goes away. Note that the DVR and home phone are NOT plugged into the same jack.

    2. I plugged a phone into this family room line to test it and it works fine and caller ID comes up when I call the home phone. So the phone line isn't the issue.

    3. Interestingly, the exact same behavior happens if I unplug the phone line from the family room DVR and plug a phone line into the DVR in my bedroom. So, it isn't a particular DVR that is having the problem.

    I have U-Verse phone and internet. It seems like some sort of interference problem, but the DirecTV and U-Verse lines come into opposite sides of the house.

    Any ideas??? Seems like a classic case where U-Verse and DirecTV will blame each other if I complain. I called DirecTV to have them come out and look at it, but that was before I discovered that the bedroom DVR has the same issue. Two different DVRs, two different phone jacks, same issue. Weird.

    Do you have the DSL Filters on those lines? I could be WAAAAY off I am just going off I know out here in KC (without Uverse) you need DSL Filters installed at every phone jack.. If I am wrong someone please correct me

    Depends how they hooked up DSL. If they ran a dedicated DSL line from your box outside, they would have installed the DSL filter in the box outside. If its piggybacking on your house phone wiring, then you need a filter for every jack in the house.

    In any case, I dont think U-verse uses filters. Sounds like the OP has a ground loop issue perhaps, or a defective modem in the receiver. Since he has the same problem on multiple receivers, that pretty much leaves a ground loop as the culprit. OP, make sure the dish is grounded at the point of entry to the house and that the ground wire runs to the SAME ground as the house electrical system (electric meter loop), and that the AT&T U-verse system is grounded to the SAME ground.

    Another thing to try is reversing the plug on the receiver (if its not polarized, I dont remember if they are or not).

    Then check the U-Verse box, and make sure it is grounded correctly. If all else fails, you might have to leave the phone line disconnected on the sat box and do without caller ID.

    If you need a DSL filter and don't have one you'll get more that just static. You'll get a very annoying noise in the phone.

    I'd just leave the phone line unplugged from the DVR if it causes static on the phone line.

    DSL requires filters at each phone and modem location. I had a simular problem with my fathers setup on his HR24.

    Caller ID was not functioning, and there was static in the line when the phone was in use until a dsl filter was used behind the receiver. After adding the filter all was well in tv and voice land once again including caller ID on the TV:)

    DSL does not always require a filter at every location. For example, my filter is outside in the box seperating the DSL line from the rest of the lines.

    Thanks for the ideas. As far as U-Verse goes, I don't think it is actually the same as DSL. I had AT&T DSL before and the first thing the U-Verse installer did was remove all of the filters from my phone lines. My phone and internet work great without the filters--it has only been an issue when a phone line is plugged into my DVR. So I'm not sure if that is the issue.

    The grounding problem sounds more promising to me. I took a picture of how the DirecTV cable comes into my house. Note that there is only a coax cable coming in from the dish (coming from the left side of the picture). It goes into a splitter and then out with two coax cables. There is a green ground wire connected from the splitter to the cold water pipe next to it. Should there be a ground coming from the dish itself? I dunno, but this doesn't look right to me. I would love to see DirecTV's installation instructions concerning grounding.

    I could live without caller ID, but I'd rather see if I can fix this problem.

    True except in the situation that Davenlr mentioned. I had them install a whole house filter with my DSL. No noise on my line and caller ID works fine.

    Ground loop issue...

    I almost guarantee that Uverse is grounded near the service entrance at the side of the house...not just grounded off a cold water pipe.

    Wait until a real tech sees the pic, but that D* installation is not, IMHO, properly grounded.

    Yeah, the Uverse comes into the house next to the power service on the opposite side of the house as the dish. I'll need to check tonight to see how UVerse is grounded.

    Can somebody explain exactly what the "ground loop issue" is? It is a little over my head.

    Ground loop - voltage difference between two grounding points. Disconnect that water pipe ground and see if the noise changes.

    Okay, I found DirecTV's installation manual. (Won't let me post the URL since I'm a noob.)

    There are two things wrong with my setup:
    1. There is no ground wire from the dish on my roof to the ground block in my picture above.
    2. The ground block needs to be grounded to the cold water pipe right where it comes into my basement.

    Looks like DirecTV will have to fix this problem. (I'm sure not climbing on my roof!) Hopefully that clears up the caller ID/phone line static issue. Either way, it needs to be done for safety sake.

    While you are waiting for the tech disconnect that water pipe ground and see if the noise changes. It's not really so much a safety issue with this low voltage system anyway.

    I tried that just now. Same thing--no caller id on the DVR and still static on the phone line. :confused:

    So does that mean it is a different issue than the ground loop?

    I had a strange problem, but it was noise on the tv, not the phone line. Where my power line comes into the house, there are three wires, L1, L2, and N. Ground is connected from the box to the ground rod in the ground. I ran a homerun from the power box to the media closet, with a 15A breaker in the box. What I found was, that the media closet was connected to L1 and N and G (115V). The plug in the wall was connected to L2 and N and G (115V). Whenever I would plug the TV into the wall outlet, I got noise on the TV (all the rest of the A/V equipment was plugged into a UPS in the media closet). After returning several components for exchange, thinking they were bad, the replacements did the same thing, so I looked further. Turned out, if I plugged the TV into the outlet in the media closet via a power strip, on the same branch the rest of the equipment was plugged into, the noise was gone.

    I never could figure out why, but somehow, the two N (Neutral) wires were not at the same voltage (with should have been 0 Volts). N to ground was 0 volts. My solution was to make sure ALL interconnected (via coax, phone lines, etc) were all on the same branch 115V circuit.

    I never have figured out why it caused noise.

    What you MIGHT try, is running your phone line through a grounded (to the electrical ground) surge protector: http://www.officedepot.com/a/produc...-EC81-DE11-B7F3-0019B9C043EB&mr:referralID=NA or a wireless phone line extension which would isolate the phone line on the DVR from the rest of the phone system: http://www.radioshack.com/product/index.jsp?productId=3908727

    The coax from the dish is supposed to be grounded outside before it enters the house.

    Tells me the grounding of the dish/coax isn't likely the issue. Good suggestions above...

    Where is your phone line being fed from?

    If you have U-Verse Internet and phone, it CANNOT be fed from your home phone lines... The phone feed comes from the universal gateway box (Yellow Ports on the rear of the gateway)....

    U-Verse is not like DSL you cannot use filters to get a phone signal on your old phone lines... Everything must come from the UVerse gateway.

    BTW, that's not a splitter. It's a ground block.

    Hmm, not sure what you mean here. The U-Verse gateway backfeeds all the phone jacks in the house, doesn't it? I assume I can plug into any of those jacks. Or are you saying something else? FWIW, I'm not using any filters.
