Z5 anti shake problem at start, black corners on display, vibrations
Display image is vibrating after i dropped the camera
black corners appear like if the lens was not in place
the anti-shake servo-motors don't seem to be able to center the lens or to counteract some shaking movement
if i hit slightly the lens, the black image corners disappear for a moment meaning that there seems to be some parts unglued or disconnected (after the shock on the floor)

This might also come from a problem with a dealignment of one of he servo-motors (horizontal or vertical) which center the lens during anti-shake adjustment. If your camera vibraets at start or shows a vibrating image on display then this is the problem. Then the lens is often out of axis and black corners appear on the display and of course on the picture... I have not found the solution but have posted a request ! It may only be some disconnected part near the lens but unfortunately nobody shows pictures of HOW to dismantle the Z5 ! and WHERE are these 'bloddy' servo-motors or alignment devices ?...
Have you attached some sort of lens shade to the front of the lens? The vibration might have something to do with the shake reduction system but I can't be sure. It certainly shouldn't vibrate heavily. You might get a better answer if you e-mail the tech guys at the support section of the Nikon website.
On Sony T100 and similar, its the vibration canceling unit, i had the same problem. if you have good hads you can fix it.( on your oun risk) 1) disasamble the camera, you will see black plastic box inside, this is he lens unit. 2) on the botom you see 2 scrwes, they are holding the CCD remove them and the ccd unit will come from the lens assembly 3) the next is the stabilizer unit it is the problematic one. it is located on the left side of the lens asebly and is held by 2 screws. you can test it by puling out the cable connected to it (the conector is just under the lens) and verifign that the problem is solved. ( you can leave it this way it will shoot fine just without the anti shake) 4) to fix it take it out ,remove the plastic cover, you see the lens on a plastic mount it should be glued to the magnet under it. the problem is that the glue fals apart. remove one of the pins on wich it slides, and take the lens and the magnet out. 5) reglue the magnet and reasemble the camera. 6) power up and test, for me that solved the problem
if you need more help you can mail me at adisarit(et)yahoo(dot)com this is spam mail so be prepared to wait a few days for reply. i have a document with pictures explaining the process .
It's actually, believe it or not, an anti-dust mechanism. All Sony Alpha A100's (mine included) do a little shake/vibration to help keep the dust off. It's nothing to worry about unless it lasts for more than a second.
I had the same problem with mine, a minor fall cracked this, I disassembled the unit and one of the springs that hold the main sensor was broken, thus the sensor vibrates instead of "floating" when the camera is turned on. There are two possible solutions: The first is to get a faulty Z6 from eBay and get the parts (the main sensor assembly) and have it replaced. (If you are not comfortable working with 1mm screws, you'd better go with the parts to a camera repair shop and explain them the problem. The second solution is un-elegant but useful: If you disconnect the anti-shake circuit from the main board you won't have the annoying vibration at start, and the focus will work properly. I've done this and I am happy with the result (I rarely used the anti-shake feature, so I don't miss it). For reference, the anti-shake circuit ribbon is the one entering the mainboard just under the left side of the screen.
PS. if you have dark spots, chech that the sensor assembly is not too out of place or that a piece of the broken assembly is on the way. Realign it in place (and please don't touch it). and asseble tha camera back
This sounds like a stuck shutter. There is a delicate assembly inside your lens that will block the light right when you snap the picture allowing the image sensor to record what it saw at that very moment. This shutter is composed of two blades that come from either side of the field of view and overlap to completely block the light. It sounds like what has happened to your camera is that one of those blades has either come off its guide or has become stuck.
The shutter assemblies in these cameras seem to be very delicate and sensitive to even minor impact. Due to the anti-shake features it will have to be returned to the manufacturer for service if you want to get it fixed.
