The screen is frequently off (black) for hours and unresponsive; HOWEVER the system seems online (
I’m sure you have but just to confirm, when the screen is black, does touching the screen wake up the panel? What about tapping the button on the side?
How do you have the panel connected to power, via barrel connector or via the wire leads connected to the back plate when wall mounted?
Are you using the included power supply and cable, or an existing cable run?
If the panel is on and you can interact with it, go to Settings > Advanced Settings > Input Voltage Test and Run it. What is the result?
Additionally, perform a full power cycle. While the panel is off, check to ensure the power cable is connected to the power supply and panel securely and that no wires have become loose.
