This sounds like an earth loop of some kind. The first thing to check is whether the cable outlet is isolated - it should be. Do you use a cable box or does the cable go straight into the TV? If you have a box, check if you still get the hum with it disconnected. If not, that's the cause of the problem and the isolated outlet will cure it. If you still get hum without the TV cable connected there are other things to check; is the TV connected to anything else? Do you have an outside aerial as well, or a satellite receiver? If the TV is fitted with a two-pin mains plug, is it the right way round? Try reversing it in the socket. I'd plump for the cable outlet first, though, it's a very common problem. -- rgds LAurence <>< ...Life is what happens to you while you are making other plans. ---Taglines by Tagzilla (tagzilla.mozdev.org)
