Does anybody know the furthest position in each direction to which you can swivel the articulated screen of the EM5 MKII without causing any harm to the internal wiring? My camera has recently been replaced under warranty due to a defective screen which suddenly happened without an obvious reason after about a week of playing with my new camera. I wonder if I've accidentally rotated the screen too far. The manual isn't very helpful here. It seems defective screens are fairly common with this camera.
