I have a Philips Wireless Video/TV Link sending signals from my Sky+ box in the lounge to a Sony KDL-20S2020 LCD TV in the bedroom.

Whilst generally the picture quality is good/excellent, the same cannot be said of the sound. Often there is a loud clicking/hissing/buzzing accompanying the picture. Often it gets worse or starts when bright colours, especially red, are present in the picture. It is a nuisance.

Previously I had a cheap 14" portable with the same problem. I bought the Sony as someone suggested it was a “cheap” set problem. But alas no.

Any ideas or suggestion on what causes it and a cure?
