It's not these major faults, where there's a black screen, or massive issue on a light modulator.
Components age, old lamp mirror replaced with a new one, and suddenly you notice, that there was just little above 20% brightness left. Color interference filters bleed over time, as do the originally matt black absorbers, which then reflect light into the light path, ruining contrast.
Plus sucked in dirt and fumes.
I do not see the idea behind a retrofit, if your projector has run in excess of 20 to 25 k hours. Yes, you may be getting a new, efficient high brightness light source, but keep the worn out parts in your projector. In case of a major component failing, add that amount to the price paid for the solid state light source, and compare to a new ultra high contrast semiconductor RGB projector, that comes with at least 3 years of warranty.
The NC 900s I service are still operating, from that side they are pretty reliable. They're just a pain if something has to be replaced. But most have lost a lot of brightness, and screens seem to cry for something elso, looking at the dim, greyish colors due to not enough light light output. After 10 years, it should be possible to replace your equipment. The write off time has expired, for some years.
