I have a Leica RM2255 that has a problem. The course feed forward and backward, on both fast and slow there is no movement. I can hear ticking sound but there isn't any movement. Is there a coupling inside between motor and lead screw that may be loose or failing. Any thoughts would be appreciated. 


Thanks

Hello,

I'm having a hec of a time trying to find a torsion spring/leg spring for the hand wheel lock, Part# 0502 38987 per the Leica manual. I've tried to modify some springs that I had in hand using pliers and clamps and that didn't go well at all. I've reached out to Leica and "crickets". Any insight in this matter will be greatly appreciated.

Hello, I am having issues where auto mode is not working...I have checked the PCB and noticed that R63 is damaged/cracked in the middle. Will that be the source of the problem? I have checked the test points as well in TP2 and everything seems to be working. Any help will be appreciated! Thank you in advance!

Since I replaced the controller board, the specimen head stops in the down position rather then the top position in auto mode. How can this be corrected?
