I am the proud owner of a beautiful lx2800 which still has a crystal clear picture and fantastic sound.......until today. I went to turn it on and all I got was the buzz sound that you get when you turn it to stand by. Does anybody know what might be the cause? I am a little reluctant to take it in for repair as the thing is so fantastically heavy. If it is a simple, tracsable, known fault I dont mind a bit of D.I.Y.The power light is on but nobodys home.
