I'm fairly new to SXRDI bought a Sony HW10 back in February and was quite pleased with it. (it wasn't perfect, but about as good as I could get for the money)
However, it seems to be ageing very badly. Unfortunately I don't have much data to support this due to a hard drive failure (I had been keeping track of it) but when I first got it, the low' colour temperature preset was very close to D65I only had to make very small +/- changes to greyscale to get it perfect. (one or two clicks)
Unfortunately you can only choose gamma presets on the HW10 rather than setting a custom curve, but using the Gamma 3 option resulted in a very good 2.3 gamma.
As it's aged, things have become progressively worse.
Every hundred hours or so when I've gone to do a touch-up calibration it's needed increasingly larger white balance corrections. Some are now around 15/20 points rather than the 1/2 it was when I got it.
The red panel in particular has become very non-linear with a big dip in the middle, but also a large spike in red from 15% or so down. Despite my best efforts, I've not been able to fix this entirely.
White balance controls reset to zero, measured last week:
![]()
Not only has the red (and blue/green to some degree) become less and less linear (it was almost flat to begin with) but gamma has gradually been declining.
What was originally 2.3 (and slightly too dark towards black) became 2.2, then 2.1 and after having another go at calibrating it today, 2.05.
I spent all morning with it, and these were the best results I could get:
![]()
(note: 2.05 is set as the target here as I had given up on fixing gamma and just wanted to get greyscale as good as it could be)
While greyscale is pretty good from 30% up, it starts becoming quite red below that, with 10% and under getting drastically worse the closer it is to black.
Not only that, but the image looks completely flat and washed-out now due to the 2.05 gamma. (as you would expect)
It's not a brightness/contrast issueif I lower brightness any further, or the low-end RGB controls, I'm throwing away shadow detail.
I've had a look in the service menu, but don't see anything obvious that would let me fix gamma on the projectorthe only controls relating to gamma are the 3200-point panel uniformity correction, and I'm not about to start changing that. (though the panel uniformity also seems to be getting worse as it ages)
Should this sort of thing be expected from SXRD projector as it ages?
Have I overlooked something that would let me correct for it?
Or does it just look like I have a faulty projector and should get it replaced?
It's not quite had 600 hours use in ≈6 months time.
Almost makes me wish I had gone for another DLP.
