I am shooting with a D7000 which I've had for 2 years. Recently, the live view switch has become sticky, doubtless due to grime underneath, but I can't figure out how to clean under the switch without breaking it off. Also, when the live view is on it constantly flickers, and the flickering shows up in any video I shoot. The video button works only sporadically, and video recording will automatically shut off unpredictably when it does work.
The AF motor on the camera also seems to have quit working, as well as the manual aperture adjustment, at least on a kit lens.
Does anyone have tips for how to resolve any of these issues, or know if it is even fixable? I've taken the camera to my local Nikon dealer, had the sensor cleaned, tried to clean out under the LV switch with a tooth brush....
