Hi Guys
Sorry for the tardy replies to all your help and advice, but I was forced by my wife to go on holiday.
I have fitted the new(er) Audio Board and the buzzing has all but stopped, it has completely stopped out of the right hand speaker and if you put your ear right up against the left hand speaker you can just discern the buzz, its going in the kids room for the PlayStation etc. and they won’t notice that amount of buzz over the racket that they make under normal circumstances anyway
So all in all I am a happy teddy bear, the kids are happy as they have upgraded from a 10 year old Grundig CRT 32 inch widescreen to a 37 inch LCD HD TV, much better picture and sound all round
Thank you all once again
Regards
Paul
