Hi,
We have a CNC lathe with 8055i controller with the following configuration (LCD Monitor + CPU + KEYBOARD + OPERATOR PANEL IN ONE UNIT). The machine was in power down (Mains Off) condition for around 60 days due to civil work being carried out in the factory premises.
Recently when the machine was switched on the display is completely white (backlite is ON) and no icons or startup messages are visible.
We have checked and found 24V is available at the CPU terminal at the back of the panel.

Any idea why the display is completely white and how should we go about troubleshooting the problem?
Is this a hardware issue or something to do with the software?
looking forward for support from fagor experts on the forum

Regards
Arindam
