The large dial on the back of my z650 no longer turns to make different camera settings. The button is the center still works. The dial does look "dirty" near the center ring. On your teardown, I see that 6 screws will remove the case. Would this allow access to the dial for cleaning, without have to disturb any of the other parts? Dirt may have also gotten inside the mechanism for this dial. A novice may be better to leave it alone than risk not being able to put it back together. Lucky the dial is stuck in auto mode, and still works perfectly.

Hello, I can see the lower left side of my tablet's screen is a little loose, I can even push a little bit and see it moving. This is causing erratic touches on the lower left (taping the "back" button) and even sometimes the touch screen totally dies (fixing it doing a block/unblock). Some friend told me to buy a Digitizer in ebay and replace it myself.

I was wondering if maybe you know what exactly is causing this behavior? and if replacing the digitizer will actually fix the issue?

Thank you in advance.
