Sure, let’s troubleshoot this together. Firstly, ensure that the power source to the NP-200R is stable and connected securely. Check if there are any error messages or indicators on the control panel. Also, inspect the wiring to see if there are any loose connections or damaged wires. If everything seems fine, try resetting the system by power cycling it. If the issue persists, it might be a deeper problem with the internal components, and it’s best to contact a certified technician for further assistance.
