I have what appears to be a broken spring for the vesa mount on my 27'' iMac display, I was using it normally and heard a small click and the monitor slipped to a tipped forward position, there is now no resistance when I try to position the monitor.
Can anyone help with this or is it a trip to the Apple shop?
iMac (27-inch, Late 2013), OS X El Capitan (10.11)
