What the heck?!: I had had a Sony 42" rear projection WEGA HDTV that I had sold two nights ago. I had replaced the lamp and I had viewed the TV. I unplugged it, then, listed it for sale. So, long story, short, the buyer has emailed me over and over that there is a blue screen. I understand the typical "blue screen," but I had just viewed it with "my own eyes". I sold it "as is," yet, I feel bad about this. HELP!!! ???- PLEASE!! HELP!!! ???- PLEASE!!
