    So you are attempting to test the voltage coming out of a single mini or receiver? Since the minis don't put out any volts at all there is something wrong in your method or tester or tester settings. The only thing that outputs anything is the hr54 if it detects a lnb to power.

    Very bizzare.

    he has ground loop
    follow the thread's discussion, I would recommend him find good electrician and fix it first
    many reasons could be for that, only checking by knowledgeable electrician on place would be productive

    Check the voltage from center conductor to the shealding, then center conductor to you ground, make sure its the same voltage....
    How close is your service ground to that bronze split bolt were they terminate?

    Everything is grounded to that ground rod.

    Did you try the extension cord from another room to this mini that shows voltage ?

    A few years ago I was having lots of electrical problems. Things kept burning up. I got a device that showed my voltage all the time and at times it would spike up to 140. I called the electric company and asked them why was it that high. They sent a pair of guys out to look at it and investigate it. They said I had lost my ground and the regulator at the station was set too high. They cut off the ends of the large lines coming into my house and put new connectors on. Then one of the guys went to the power station / sub station ?. They communicated on the phone. 1 read the voltage at the house while the other one adjusted something.
    They got the voltage down to 124 and told me that I should not have any problems now. So far everything is running smooth and not burning up.

    What is your voltage in the house and does it vary from outlet to outlet ?

    I will try that tonight. I will try another meter to be sure, mine reads 120v at my electric outlets though.

    118 to 120 v I did replace the receptacles in the bedroom where I'm having the issues. I checked polarity on the outlets on the circuit also. I do have the big high tension wires within 250' from my home.

    Did you check the voltage from the HOT to the neutral, and the HOT to the ground?

    he will need simple tester (HomeDepot ?) what is plugging to receptacles and does show ground/neutral/hot lines fault

    I have a ac 3000 ac sensor I checked all 8 outlets on the circuit in question and the light light up on the hot pin the short pin lol on the right. I will check the hot ground neutral ground and hot neutral this evening. I have one switched light on the circuit I did not test that.

    That is not needed......You do the same thing when checking the HOT to neutral HOT to ground.
    If the ground is open it will show no voltage.....If there is something deeper (floating ground) he will get a different voltages.

    You say when you were testing the circuit by plugging stuff in one at a time you plugged the TV in and didn't show voltage, then plugged in the mini and showed the 30 VAC. Was the mini connected to anything else via HDMI, audio, etc. such as the TV at the time you did that test? In order to be valid everything you are plugging in should not be connected to anything else in any way. Just plug in, turn on, and test with no other cables connected. Otherwise a faulty TV (for example) could pass rogue current on the HDMI shield to the mini, potentially interfering with the audio, or resulting in the voltage you observe on the coax.

    Also, in order to fully isolate the mini, try plugging it into that circuit by itself with nothing connected to it except a short coax jumper, then test the voltage on the cable. Then try the same thing with your other mini plugged into the exact same plug, and using its own power supply. Depending on whether you see the voltage on neither, both or just one you'll narrow down the issue. If it is on both it would seem to be an electrical issue, and testing the voltage difference between hot and neutral, hot and ground, and neutral and ground might be the next step. If the voltage is on neither, it isn't the mini that's at fault, that's just a symptom, and you have to look elsewhere. If it is just one of the two, then that one is likely faulty and you should have Directv send you a replacement.

    Fingers crossed I may have found it

    most likely he found broken ground connection somewhere in the house

    No house electrical issues in the house. It is these newer tvs allowing voltage to pass through the hdmi cables. Take a rg6 cable to one of these high dollar surge protectors with cable connections on them from your tv and there will be zero voltage on the home cable lines.

    Interesting reading here.
