M262 shutter speed can't change anymore

Just bought a beautiful 262 a couple weeks ago.  Been shooting fully manual with Voigtlander 50 and 28.  No issues whatsoever.  Today, I cannot change the shutter speed.  I turn the dial, which still feels the same, and release the shutter. 1/4000th and 1/4th make same sound, for same duration.  Same exposure (1/24 and 1/30) every time.  The camera was not dropped, jarred, or banged against something.  Took the battery out, changed lenses, still no improvement.  

I guess the next step is reset the the whole camera.  Could this also be a physical disconnection under the dial?  Maybe something has come loose?  Any thoughts would be greatly appreciated.  Thanks!

I’d send it off straight to the workshop or if you want to risk it  and have tools you could try looking under the top plate yourself. Could be just a bit of accumulated crud blocking contacts, but tools and steady hands are recommended.  Can you switch it to A mode and check if those are only shutter speeds available? It would tell you if it’s mechanical problem with shutter speed selector or something much deeper with a shutter itself. 
 

if you don’t have tools to remove top plate maybe just try to slide a small piece of paper under shutter wheel few times if there’s some dirt maybe it will work for now.
Edit: Just checked on m10 there’s not much space between top plate and shutter wheel, and top plate seem to have a convex dimple to guard the innards from dirt etc, you can try blowing some compressed air around it just be delicate

Dodgy SD cards can cause various camera problems and malfunctions. Is the camera fitted with a good quality non-fake memory card and has the card been properly formatted? I'd try deleting everything on the SD card using your computer's Disk Utility / Disk Management facility and then reformat the card in camera .

Thanks for replies!  Unfortunately, didn't do anything.  Tried different SD card (8 gig that worked perfectly before), formatted in camera.  Also, tried a piece of paper and a rocket blower under dial

Switching to A mode does nothing also.  Seems like contact between dial and camera is broken.

Changing battery to fully charged one? 

[mister bee]

Can't hurt!  It's 45% now.  I'll stick in the charger.  Only have one battery.

You’re not the first one with this problem, it seems a factory reset can be a home remedy. Fingers crossed

Thanks Carlos!  I did read those posts before posting, but went through them again.  The reset didn't do anything.  We'll see about leaving the camera off for a bit, while the battery charges.  

I'll try some exposure bracketing tests when i power it back up.  I guess if the camera brackets with different shutter speeds successfully, we can deduce it's a dial contact issue.  

EDIT:  Or will it use ISO to bracket?  Not sure, i don't usually bracket

I’ve just checked it on m10 bracketing with front button and thumb wheel treats shutter speed  as variable but only on A with manual speeds it does nothing.

Alright, we're getting somewhere!

Just tried bracketing.  5 pics with 2 stop aperture differences.  Camera took pics from 1/360 to .7 sec.

Tried dial.  Still Nothing.

Then, I rapped the top of it with my knuckle.  Movement!!  Shutter speed now changes.  But wildly out of alignment.  1/4000 is 1/180.  But it moves incrementally, one stop at a time.

Now...alignment.  Any ideas?

Your "next" step is simply to return the malfunctioning camera to whomever you purchased it from!
