Especially as this is the second time it’s happened.
I can't see how. It's up on the ceiling in a vaulted ceiling room with like a 3ft drop pole. There is nothing around it in any direction for at least 3 feet and that's the ceiling.
I go around and calibrate friends and stuff projectors and I have seen a fair number of Epsons with the red tint issue.
You can google it and find plenty of people reporting the issue as well. Probably it's less more recently but I was surprised even a friends LS10500 had the same issue even though that's LCoS not LCD. I think it's the polarizer panels, not the LCD panels that have the issue.
Even my old Panasonic AE-8000U started red tinting on one side (though that took about 5 years) and as far as I understand it uses Epson 3LCD tech.
Here is my friend's replacement Epson after about 6 months.
First one did the same thing after 11.
The model is https://www.projectorcentral.com/Eps...inema_1450.htm
But I have seen it on various other Epson models including UB as I have gone around to friends and other places to do some calibrations. I have nothing against Epson but it's just something I have notices more than a couple times.
The only projectors I have never seen any sort of color degradation over time are all DLPs and JVC LCoS. All the older Sonys I have calibrated all had varying levels of Blue tint that needed to be corrected but at the cost of a little contrast.
JVCs have gamma droop. My NX5 had it right out of the box, but after I fixed it, it has not changed in the 300 hours I have used it so far since.
DLPs seem to remain the mot stable over the years in all regards in my experience. They also tend to have less dust blobs as well.
If only RBE didn't bother me so much and they weren't such low contrast haha.
