2007 Norge LCD display issue

Another question, the LCD display is blank most of the time, sometimes when you turn the ignition on you get a very faint MOTO GUZZI logo and for a few minutes can read the display then it goes faint and disappears and won’t display again until the bikes been left for a while (normally overnight) all the clocks work as they should, the dash is illuminated and indicators etc work.

So far checked the connector block on the left under the tank cleaned all terminals and made sure all were connecting properly, also checked and cleaned the main one on the back of the display, when it does display all the data is correct
