Question about Optoma Office Equipment & Supplies
Hi, I recently bougth an Optoma UHD50 and when I use it with an HDR source, works just fine. But when I change to any SDR source, after 30 min, "fan locked" warning pops up and projector shuts down. The projector is still under warranty, but unfortunately I can not RMA since I do not live in US and transportation costs to/from service center, are just too high and the option is not cost effective. Any advice you could provide will be extremely helpful. Thanks

Your best bet on getting your hands on a Service Manual would be to contact Optoma themself.
As for changing the colour wheel , it is pretty straight forward if you were able to open up the unit and get to it.
The colourwheel is mounted with three tiny scrws to a bracket in which it sits. And the bracket in it's turn is fastenend to the body of the Projector with two tiny screws.
First unscrew the bracket from the casing of the Projector and then take off the three screws that holds the Colour wheel to the bracket. Replace and do the whole proses again - but obviously just the other way round.
This is really easy to do yourself.
Give me a shout if you need any further assistance.
Thanks for using Fixya and good luck.

Hi, I'm not sure if it's the same problem I had..
I had it on picture mute, for maybe 15 mins, which may not have been a good idea. While it was muted, it made a sparking sound, and then a very loud grinding noise. When turned off, the lound noise stops, and the fan continues as usual for about a minute. As soon as it's turned back on, the grinding noise is back. But the logo seemed to display ok.
I took it in for repairs, and they said they needed to replace the color wheel to fix the problem.

Set the projector to "high altitude mode." It will be noisier, but won't overheat. I wonder whether using one of those $10-$20 laptop coolers underneath it might be a quieter solution.

It's not a short, the blub is near the end of it's life ~ the optoma is designed to detect when the blub is about to blow and shuts itself down. Turning the projector upside down or right side up usually only gives you a brief reprieve (some have reported a modest amount of extra time gained) on the blub ~ but in the end it's on it's way out and the projector will shut down again.
