Hi, I've had a Philips 28PW9616 for around 18 months now. Everything has gone swimmingly and I have been most pleased with its performance bar one major point. The wireless rear speakers. There is an audible hum/buzz/whistle that comes from them and changes according to where people are sitting in the room. Occassionally the sound will drop out completely. It is pretty obvious that there is some interference in the channel used to transmit the sound to the speakers. I have tried fiddling about with the switches on the speakers and back of the set (defining the frequency to use) but to no avail. Has any other owner experienced this and/or managed to remedy it? My other more minor disappointment is also sound-related. Although I find the sound pretty satisfying for a one-box solution, I have found that when cranking out a DVD at typical movie, volume speech can get very difficult to hear and understand. Anyone else and any solution? Thanks for any advice in advance.
