I had put the thing back together and put it up on the shelf. Will have to open it up again soon and look into the color wheel.
What is the actual failure mode on these things? Mechanical, like bearings drying out and dragging? Why would the unit always lock up into B&W mode, rather than red, green, or blue? According to the pictures I have seen of the wheel for this unit, there are 4 filter segments, R, G, B and clear. If the wheel stopped rotating randomly (as from a bad bearing), wouldn't there only be a 25% chance of landing on the clear segment each time?
