Our C-more hmi screen went dark at one point. After power cycling, the screen shows ""no system found in the panel," and the LED status in the back side shows no light except the CPU status LED is steady red (reddish orange).

I tried using the C-more recovery tool but just cannot establish the USB connected to the panel.

I found multiple manuals and tried uninstalling/reinstalling the EAC9USBDriver.exe, but in the device manager, the panel always pop up as the unknown device. I follow the manual to reinstall the driver, but always the same result.
 
Typically with Cmore, if you touch the upper left part of the panel for three seconds it will bring up the system screen. You can do a factory reset from the menu
