I recently acquired a GM5, a beautiful and capable little beast, and I immediately fell in love with it. However, the rear dial didn't work properly. This problem has been reported in another thread (GM5 - Broken Control Dial) and the suggestion given there to spray a contact cleaner seems to work for the moment. However I am realistic and I don't think this will be a permanent fix...

So I tried to open the case to access the dial and clean it more thoroughly. A new dial may also be bought for about 25 USD on eBay if necessary. However problem, I have not been able to open the case. The rear case opens partly, but there seems to be something holding it around the viewfinder. I didn't want to force it and break something...

Therefore I need help, either:
- someone who has opened the case of his GM5 could tell me how to do it,
- or if I had the service manual I would probably find the solution there. I did find service manuals for the GM1 and for the GX80/85, but neither offered the solution. And I can't find a service manual for the GM5.

Thanks for any help...

Viewfinder is similar to GX85, so I would guess there are 2 ribbon cables that are keeping the back partially attached. I bent one of the delicate little pins getting mine back together and now don't have the green channel in the EVF.
I strongly suggest leaving the back partially attached to the top and working around it if possible. Otherwise, use extreme gentleness in reattach in those ribbon cables. They are expensive ($130 for VFK1950) and not readily available.
But the overall process on the GX85 was about finding all the screws and detaching ribbon cables. Not actually difficult at all. I was also replacing the rear dial - a Panasonic design flaw.

I think there is something else, as I can't open it enough to even see these ribbons. I imagine something else like a clip or a hidden screw is keeping the parts together.

Bumping this thread up as I'm also very interested in the answer
Could they be locking tabs like in DJI drones?
Would have to press in a specific direction on slide in some thing plastic tool, tried everything but realized I'd probably end up breaking it.

Let us know if you found a solution, or if a GM5 service manual is available somewhere (don't mind investing)

Finding the GM5 Service Manual would seem to be the answer. Panasonic websites don't have it available?
I remember screws in odd places, especially around the EVF.
And BTW, I strongly suggest ordering the part, You should replace it, not just clean it; and it took almost a month for mine to reach my door.
