Up until now I have had no problem changing lenses on my 500c/M.
Today a 500EL/M arrived, the little switch that has to point to the red dot was completely off. Silly me tried to put a lens on.... did not work. (Duh!)
Not only that, the lens switch is also off its red dot and wont fit back on the 500C/M
Can anyone give a a tip as to how to repair this? I dont want to go at it with hammer and screwdriver.
Have you checked if your EL/M has a charged battery inside? It looks like the body has fired and needs to be rewound by the battery, while your lens is probably cocked correctly. If the lens is a pre CF version, you can try to fire the shutter with the self release present on the lens to see if it works.
