I did have to argue with the technician when he said the best he could was offer me a new lamp at a discounted rate. He tried to tell me there is no known issue with the bulbs. I then said, "yeah that's the reason you have gone through 3 different designs - the latest having an entirely new piece to enhance air flow." After saying that and reminding him that the specs suggest 2,000 hours on a bulb, he offered to send me a new one if I could send him a picture of the projector displaying the current # of hours. I did so and a new lamp is on its way. Kudos to JVC.
I'm glad to see them standing behind the product. The Rep I talked to told me the same thing. I just laughed at him.
So far my second lamp seems to be holding up well. At 50 hours and aperture closed all the way down -15. It is still blistering the screen! On certain scenes it is almost too bright on my 120" screen. Contrast and black levels are superb! Sherlock Holmes and Haywire look fantastic!
On another note,
I was talking to a good friend, who is a store manager at a local audio/video shop. He discovered certain DVD players crush the blacks with his RS40.
We tried for hours to calibrate the contrast and brightness of the unit. It was either to dark or washed out. After swapping Denon BD players. The unit looks much better! This leads me to believe the color space output of certain devices can give you the wrong impression of this projector. Robbing it of its dynamic range.
So far a WD TV live has given me the easiest to calibrate output. Using it I can get the pluge pattern for brightness to flash all the way down to 17 without 16 flashing at all. I've never been able to do that with any other output device I've used. For some reason YCbCr 4:4:4 output from the WD gives me greater accuracy on the pluge pattern. I have no idea why though?
