I have an UM3 and my display started to loose intensity. I therefore got a replacement display I put in last night. The display apparently came up fine with a crisp clear image, but I was only able to operate the menu 3-5s after the bootup had finished before the menus froze.
When I put back the old display everything was fine (except the display intensity) and nothing froze. The two displays are apparently identical in terms of mfg part number.
So, a replacement display makes my UM3 freeze. Defect display of anything steps to countermeasure this?
