PR4100 LCD display is stuck

My Cloud OS 3 Personal & Network Attached Storage My Cloud Pro Series

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

Yes, I have already tried restarting it and turning it off for a few minutes.
the screen does not change, it is still stuck

I launched the commands but still nothing, I tried with more and less characters and the only thing I got was to change the opacity of the boxes.

Manually re-install the firmware and it stayed the same, there was no change.

Could it be that a hard reset (with the paperclip) can fix it?

I was able to solve the problem:

The problem was that the NAS needed an internal cleaning. Where the LCD Display is connected there is a ventilation grille. Moisture, dirt and dust can get in there.

What I did was:
Open the NAS, removing only the 3 rear screws, disconnected the strap (from LCD Display to Motherboard) and gently cleaned it with isopropyl alcohol, waited a few minutes for it to dry, reconnected everything and that’s it. the screen worked again.
