Question about Sony Grand WEGA KDF-55WF655 36" Rear Projection HDTV

Blue dots in KDF-60WF655

I have blue dots in the middle of my tv screen and also a blue haze in the lower left and bottom left of my tv. I talked to Sony and they said this is an isolated issue on this model. Looking at several websites, it appears this is a common problem, but my model number is not listed as having issues. Is this also an optical block problem in this set?

Yes, your optical block ( light engine) is bad. Heat generated by the lamp circuit with its poorly designed ventilation system, cause the LCD panels inside the light engine to fail. They are the size of a postage stamp. There are 3 LCDs, for red, blue, and green. The heat causes them to warp and de-laminate.

Sony has systematically downed played the scope of this issue. It appears however that virtually every LCD projector they make can develop damage in the light engine which is extremely expensive to fix.

I suggest contacting Sony and your state's attorney general's office of consumer complaints asking for action on this.
