I-Cue Start Up Issue

I have an I-Cue that isn't starting up properly. It doesn't seem to be a power or DMX issue. When it starts, it homes to about a 45 degree tilt to the right side consistently. The board can move the mirror normally, but it doesn't have its full range of pan motion to one side. I'm inclined to think something happened to it when it was being used for classes without my knowledge or being there.
Is this possibly a mirror mounting position issue that can be fixed by physical adjustment (ie, can I fix it), or is it indicative or a larger problem?
Thanks!

Is it possible it was switched to or from 8-bit mode rather than 16-bit mode, or that its starting address has changed? Or, conversely, that it's been patched to a different address on the board?

That's where I would start looking. There are some other possibilities (someone parked one of the parameters, or assigned a curve or proportion to it) but those are fairly under the hood.
 
Everything that I can check (patch, mode, etc) are as they should be. It seems like it is a startup issue. Every time it boots, it homes to the 45 degrees off center position.
 
Is it possible someone wrote a new Home preset for it? Or inverted the pan or tilt (or swapped them)?

If it's a hardware issue (e.g., an encoder not reading correctly) there's not much you can do on the user end, other than request a repair.
 
Is this I-Cue very old? Almost all problems I have seen with these are due to a worn motor.
 
They aren't super old. 5-6 years at the most and they don't see very heavy use since the school only does 4 shows a year.
The show comes down this weekend. I'll take the other working one home and run some tests with both of them.
 
Just to update for posterity: the issue was the mirror slipping on the shaft. Just had to make sure it was seated all the way and tightened the screws back down.
 
Since this old topic got brough up, why do these motors wear out so much?
I've used so many moving lights with motors that last dozens of years, but I Cues have always had issues where the magnets wear causing the mirror to jump. I've had experience with disassembling the servos and cleaning out the magnet dust to get another year or two before replacement, but sounds like others have had similar issues...
 
I don't think mine was a motor issue. Just the set screw that holds it to the motor shaft.
