I recently formatted my PR4100 and the lcd display was frozen, it does nothing, the navigation buttons do not make the screen react either.
the screen looks like this: blue background with white squares.
I checked the settings and all the changes I make to the display don’t seem to have an effect.
is there any other option to solve this? could it be an update? the one I have installed is 5.17.107
Note: the NAS works fine, I can load, review and view the files of all devices, the disks have no problems (according to the diagnosis) and the only problem is the LCD display
