Tv interference we have a tv in our conservatory. from time to time we turn it on and there is a buzzing noise. it is not the tv because we recently changed it for a new one and this and the old one had the buzzing noise. we pull out the plug of the tv and the satellite box and leave it for a while and most times it rights itself. i wondered whether there could be resistance building up in the plug or the wiring to the socket. help would be much appreciated.

I believe it may be a bad coaxial cable in the back. It is a common to both the old and new sets and they can cause all sorts of strange interference. By unplugging the cable box or TV, you may inadvertantly be moving the coaxial cable, enough to correct the internal short. As time goes by, the short manifests itself again and starts the process all over. I would try a new set of cables, they are cheap, much cheaper than an electrician or a new TV! I have seen it before in my 8 years of CATV.

It definitely sounds like a bad grounding problem you may have. try leaving the satelite box unplugged and just run the TV alone with maybe some rabbit ears to see if the buzzing problem persists. If itdoesn't seem to come back then i'd say you have a problem with the satelite box. If the problem is still there even without the satelite box running then you might want an electrican look at the outlet your set plugs into.
Are you by chance using a 3 prong surge protector being plugged into an adaptor to avoid the ground to be plugged into a 2 prong outlet?

If youre sure its not the tv, I guess the electricl socket is at fault. This needs to be checked, or replaced, esp. if the TV's plug tend to build up some heat, which coule eventually damage it. I suggest calling an electrician to do the job

Do you have a baby monitor or cordless phone or even a cell phone plugged into the same or close outlet...any such thing can cause interference.
