Epson 5020UB operating temp and auto iris noise within normal range?

post #1 of 3
Thread Starter 
Hello all, just a few questions about my new projector. I did a search on these topics, but couldn't find an answer. I am new to projectors and was wondering if these concerns were normal?

1. Case gets very hot while running. My projector is rear shelf mounted, but has air flow all the way around. I don't get any warning lights or anything like that. I understand there is a several 1000 degree lamp burning inside, but it just seems excessive. I can however leave my hand on the case where the bulb is located for a while.

2. I am not in a high altitude, but should I run it in high altitude mode to make the fans run faster and keep the unit cooler?

3. There is a pretty constant low buzzing noise when I turn on the auto-iris that can be heard in quiet scenes. I tried putting cork tiles underneath the unit
to keep the sound from transferring to the shelf, it helped a little bit. It is not crazy loud, but wonder if others can hear the noise?

4. When I turn the projector off properly, the fan only stays on for about 20 seconds, is that normal?

The picture is really stunning from the projector and want to enjoy it for years to come. Thanks in advance for your responses.

I can answer #3. Yes there is noise from the auto-iris which you will hear when there is a dark scene. Also get ready for the light flickering that is caused by the auto-iris. This is a very distracting to me anyway. Some will tell you just to turn off the auto-iris if you have this problem but in order to get the best blacks you need to have it on.

No, overcooling can do as much damage as undercooling. Only turn on high altitude mode if you're more than 4921ft (1500m) above sea level. So long as your projector is in a room temperature environment (according to the manual the operating range is 41 to 95 °F (5 to 35 °C)), and you're cleaning out the filter on a regular basis, it should be fine.

Check to see if there's a Quick Power Off option in the menu and turn it off. I couldn't find anything from skimming the manual but you never know.
