I don't have an MX to look at so I might be wrong but
on the other M bodies the hot shoe hits a spring contact
inside the body. It causes this frequently.
Remove the silver plate with the "X" in it by lifting the
front and sliding backwards.
Remove 4 screws and lift the hotshoe off.
Clean the contacts you see in the camera and on the hotshoe.
(Pencil eraser)
Re-assemble and test.
There might also be a set of contacts on the hotshoe to
disconnect the center contact when the flash is removed.
If so clean these too. (they are on the underside and look
like switch contacts)
Easy, but take your time.
I have been able to disassemble, clean and reassemble the hotshoes of
both MXs thanks to your detailed instructions, Don.
But the "old" (silver) MX doesn't want to fire the flash like it did
last week, and the "new" (black) MX has improved a little: now it fires
the flash at the very first try, but to fire a second or third flash you
need to switch off and on the flash unit every time you want to use it (?)
Thanks again for your instructions, it has been very educative to
disassemble the thing without any problems, and I even managed to do it
without breaking anything. Amazing!
