On a new GMC-300E+ the display text disappears after a second.
Some buttons and the usb reconnect make it reappear for a shot time.
The short time is 0.1 to 1 second.

Checked the lcd cable. It is soldered / no connector.

Managed to set swivel mode. Now the text is flashing but barely readable.

Menu shows firmware version 4.82.
