Oh, pretty happy to have stumbled on your post. Thanks for posting. My issue was that as soon as the camera lens attaches, the screen (also EVF) was blinking, switching on and off, after roughly 20s LCD displays "Lens Error". None of the simple and usual fixes did not help, like cleaning contacts, or rewriting the firmware. When started dissassembling the camera, one long screw fell out. I think it was exactly the same like yours. The one holding an metal piece for a strap next to a shutter button. It must have shorted something too. Now I need to somehow find what exactly got shorted Edit: I opened up and took out the main board. Nothing for my untrained eye looks damaged. But one of the fuses on the back size (Fuse has printed O symbol on it) has high resistance. Not like others which show resistance close to tester leads / cables. Does that mean that this fuse is blown? Edit: Replaced the blown fuse, screen is still flashing with lens attached, other 2 fuses does not appear to be blown. All other usual methods like cleaning contacts, multiple lenses and so on are already tried.
