I've had my RS2 since it was a new product and it's my primary display- at least six hours a night every night. It's run tirelessly needing nothing more than new lamps and the occasional cleaning. I think I'm on my fifth lamp and milked them all for about 3K hours, so it's got a few miles on it. It's run in a dedicated and pretty clean room with its own air handling and filtration.
Recently, it's begun shutting down after running a while. It's pretty random, but of late (after switching to HA mode per below) it's been about every two hours. It's done that before when a lamp was going, but that's always been accompanied with other problems.
I thought maybe the fan was going or had become gunked up. It's still putting out air pretty well, so it's not failed completely. I switched it to "High-Altitude" mode which seems to run the fan more, and seemed to make things a bit better, but not fix the problem.
I tried cleaning it more as well as switching the lamp with a different (admittedly well-used) one, to no avail. Current lamp only has about 1500 hours on it and still looks good. It's a genuine JVC as was the spare. It's not having any of the usual bad-lamp symptoms (problems starting up, that weird clicking/buzzing sound, dim image). Well, unless overheating counts, maybe.
Is the fan easily replaceable? Can it be disassembled cleaned and lubed? Has anyone else had this problem and fixed it? I would totally believe it's due for a new fan just from the amount of use it's had, although it's still putting out air and the fan isn't making any odd noise.
Only suggestion I've seen to remedy this problem is to get a new lamp, but I'm getting skeptical that'll work in this case (since I tried using a different one already). I will try another old one next I get a chance and will likely replace it with a new one if I don't hear any better ideas. I'd certainly like a plan B in case that doesn't fix it, though!
