Just noticed I have lost all the horizontal channels on both satellite
rxs......is it as simple as a duff lnb or coupled with the fact I am getting a shock off the outer of all the f connectors could it be a cable/plug fault ......I get the shock with either rx switched on or both on so probably not the rx.????...not got any test equipment here at the static van so probably start with bringing down a new four way lnb the next time I come down ? .....if that doesn't cure it check all the cables for shorts? ....anybody had this fault?... |

I wouln't think the events are related. A working recceiver has a very "feelable" ac Voltage on the LNB output. There is not usually a ground on the receiver and the capacitive leakage from mains to equipment provides the "tingle". I do ground the receiver now when setting up a system on damp ground. With no direct means of measurement a spud will detect Voltage and polarity. Plus gives a blue ring. I did have a discussion with a marine Engineer who said that the spud had to be a King Edward. I don't actually think this is the case, but since the introduction of DMM's I never really had reason to check. AB |

If a system isn't earthed and it feeds a lot of sat boxes you can get a real shock off the dish. You might be able to google something about the fact that you can feel the 50Hz if you move your finger across a painted cover. It only works when it's painted. Bill |

Disconnect both at once. If you still get a shock from the dish cable it's static on you, discharging to ground. Got new nylon carpets? I could tell you a story about a large TV shop where there was a major scare about earthing etc due to having new carpets. We fixed it with a plant sprayer filled with water. For a few days anyway!
