Black Screen on Onefinity CNC Controller Touchscreen Need Help

Hi everyone,

Iam experiencing a black screen issue on my Onefinity CNC machine’s touchscreen controller. The machine powers on, and the controller lights up, but the screen remains completely black, and I cannot access the interface or run any programs.

Checked the power connection to the touchscreen.
Restarted the machine multiple times and performed a hard reset.

Tested the HDMI and USB connections to ensure they’re secure.
Updated the firmware recently, but the issue persist

Could this be a firmware bug, a display issue, or something else?

Any advice on troubleshooting this would be greatly appreciated!

Thank you for the advice! The screen remains completely black screen with no blue splash screen. I will double-check the connections and ensure the Big Red Estop is released as suggested. I will update here after trying these steps.

I have the same problem every now and then. It’s happened if I accidentally cut power or need to turn the machine off and back on. I usually ulplug and the display from the back and plug back in and it comes right back. I don’t know what the issue is.
