Hi I'm having a problem with my Bravia 32'' tv model w5500 bought approx a year ago. The reception and picture was excellent for about 9 months then the electronic programme guide disappeared follow one one channel after another. Some days I can only receive two channels. The others say no signal. Nothing has changed regarding ariels or any socket. My pioneer plsma in another room connected to same ariel on the roof has no such problems. I have been told the signal comming out of the socket is too strong and this is the cause of the problem and not the tv is this right?
