I’m following the discussion on AVSforum, and have some comments. First of all, thanks for not quoting me by name. My largest customer is the Sony distributor in Norway, and they will not be pleased with me going public with this info! They have a proses going with Sony regarding this issues, but for the last 6 months Sony has not answered back.

Regarding the measurements you did on your VW600. You describe loss of brightness (due to lamp), and black level “as it was”? You should have measured the same loss of brightness in near black, as you did in white. The fact that your gamma is of targets should prove my contention. The big surprise comes when you replace the lamp, and the brightness returns. Then you will experience the same increase in brightness throughout the gray scale, and you are left with significantly poorer black levels.

By the way, at least one of the guys who has commented on AVSforum is a previous VW1100 owner. Of course, both he and the other earlier owners fail to discuss the problem, because they will not be accused of having sold a defective product. All the Norwegian customers where ignored by Sony regarding this issues. Leaving them with only one option to get rid of the projectors without loosing too much of money.
