Shoot first, think later
Ok, just so I understand this correctly - could someone confirm that's possible to clean all the typicaly sticky parts of the shutter without having to cut/solder anything? If so, that is GREAT news.
YES!!! and thank you! I was going to PM you but was a bit shy about asking 😱 PM on the way 😀ferider said:Yes. Andy. In fact, I'll clean your camera if you like.

Fixing the shutter problem is very easy to do.
Follow the disassembly instructions on Ryuji Suzuki's Silvergrain website.
This includes the 5 external screws, and the 3 short screws holding the aperture ring, shutter mechanism and exposure comp functions PCB in place.
Rest the camera on its back, using a very fine bladed screwdriver, prise the metal top enclosure off the Misaki shutter switch assembly, taking care not to lose the tiny black button when the metal enclosure comes away. A firm action required to do this for the first time, as on mine at least it was on tight. Prise from the front, at the leading edge where the metal enclosure is secured onto the plastic mounting below the plastic flange that holds it in place.
Using a cotton bud, and ether, rubbing alcohol, Permaclean record cleaner or similar, wipe the corrosion off the contacts of the switch assembly plastic base, as well as the loose internal metal contact part that acts as a trampoline. With the domed side facing upwards, check the 'legs' of this piece are all bent the same way (they appear to invert through use causing many of the problems with AF focus and intermittent operation. If they do not appear to stand up the domed metal part equally all round, bend gently at the noticeable fold and using tweezers, away from the domed side, so that it forms a perfect 'trampoline' for the black button. Reassemble, snapping back on the metal switch assembly top cover, and reassemble the camera.
Follow Ryuji's advice to ensure the hot shoe wire slip into the gap that stops them getting squashed by the top cover of the camera as you gently put it back. Please remember to do this whole operation with the battery removed.
I am no repair expert, have no experience mending delicate electronics, but this job was easy for me to do - all without desoldering the switch assembly.
