I recently bought an Arri 16S and it arrived earlier today.
The camera seems to be fine (as far as I can tell) except for the on/off switch. The on switch presses down and clicks into place, however when I press the 'off' switch, the on switch doesn't spring back up. It works only if I hold down the 'off' switch and manually pull the on switch back into place. (Please let me know if I'm not being clear enough)
Unfortunately I don't have a motor for the camera yet, so I can't test how it works with power.
So does anyone know what the problem is? Does it need some oil for the 'on' switch/pin?
