    Are the yellow spots there on any input? if so the problem may be the lcd panels in the optics unit. google sony optics for any possible warrenty extension for this model.

I get a red and yellow bar at the top of the screen


this problem has to do with te optics in the tv...not the lamp. I had the same problem, even after replacing the lamp. I called sony & they are replacing the tv with a 2010 Sony Bravia 40'. Free! For a fee of $325 I could have got a 46" or for $725 a 55". I went with the 40". Try working it out with sony. It worked for me and only took a 5 minute phone call. Good Luck

Yellow tint


The LCD green or blue inside the optical block is defective now. the optical block is the core of the tv (is the projector inside the unit "expensive"). make sure calling to Sony company and try to see in your particular serial # is covered under an extended warranty for this particular set. or at least ask them where you can get a good autorized workshop close to your area.
