Preenfm static electricity problem

[Jalex]

Hello! did anyone have a static electricity problem in preenfm?

If static electricity falls on a metal panel, the image on the device disappears and flickers. Reboot helps. The case panel contacts only the case of the screen. isolating the screen from the metal panel of the case can solve the problem but with construction of my case it is too difficult. 
Did anyone try to ground the case?

Grounding the front plate through the Standoffs would be the easyest.
You can just wire a GND wire to the screw on the PCB side. This will ground the Frontplate through the metal standoff/spacer.
