Same issue here, when I turn the camera on, the rear LCD does not come on, until I move the screen a little away from the body. it then stays on until another power cycle.. I am using a Tilta cage. it has a magnetic tool mount right below the hinge of the LCD. ive noticed that if I remove the tool (but still leave the magnet in the cage) the function is normal. So having the tool actually mounted changes the pattern of the magnetic field and leads to this issue. Looks like I have to do without the tool being on the cage - a pity, but at least its not a fault with the camera!
