There is a high pitched whistling sound from the back of the TV. It occurs after the TV has been switched on for a few hours. It is a similar sound to a 'worn' power valve from old TV times. I fixed that by tapping the top of the valve to discharge the gas (so I am told!) When I waggle the AV1 scart at the back of the TV the noise varies in pitch and sometimes stops altogether (although more often than not the noise comes back again. It is almost as though there is a whisker of wire shorting out. Sometimes it is louder and higher pitched than others. There is also a low pitched continual buzz (not a hum) from the TV but this is not loud enough to be annoying as you have to get quite close to the TV to hear it. It can get worse if the DVD is switched on but judicious manoevering of the DVD minimises the effect (electro-mechanical/magnetic interference possibly?) However if the TV is left alone the high pitched whistle goes away of it's own accord; usually after 20-30 minutes. The TV is just over 1 year old. Any ideas for a, preferably cheap, solution.
I wonder if there is enough air circulating around your equipment?? My DVD recorder makes a sound unless I open the doors on the cabinet that contains all of my equipment. The cable company says it is a fan to cool down the units.
