We have a sony wega KFWS60. It is displaying a blue film on the bottom of the screen and have noticed 1 blue pixel in the middle of the screen. Can you help Therese Smith

Do you mean KF60WE655. I don't recognize the model you show. I'm sure your talking about an LCD rear projection Sony. Your trouble is in the Optics ( light engine). Over time the Lamp has destroyed an internal filter ( glass element ) . This Blue haze or film will probably continue to get worse and grow across the entire screen. The only fix is to pull out the Optics and send off to Sony or another re builder.
Up until June 30, 2008 some of these models were being fixed at no cost by Sony.
