technobeam color wheel problem

I have a technobeam tha
t just yesterday the color wheel stopped working. It jerks a little like it's trying to move but won't spin. There is a fair amount of resistance when trying to move it by hand, not sure if that's normal. No unusual output on the lcd. Any ideas?

Also I have another one that blew its main fuse, after I replaced it, the unit works fine except shows spinning letters/symbols on the led 24 hours a day, whether on, in use or idle mode.

Thanks!

    [quote=tadawson;44313]There are very, very few cases where a board replacement is truly in order. If all else fails, give LightParts a call - they can usually service pretty much anything for well below the cost of replacement.

    Any chance that you errantly swapped a chip that wasn't a driver, or got one in backwards? Just swapping stepper drivers should not be able to cause a problem like this . . . .

    it was a total pain in the ass, i switched them one by one right to left (with the fixture in the air mind you!)

    the only thing i can imagine is either A) one of the leftmost chips arent drivers, b) i got the chip in 1 pin off, or c) a pin got bent and didnt make contact properly.

    you think they can fix the board? i will call them tomorrow

    Thanks
