3 Troubleshooting
3.1

Overview

The Entero RPMSP/RPMWU/RPMHD-LED01 offers a comprehensive system of diagnostics, tracking a
wide range of conditions and alerting the operator to a potential problem by display specific status information
at the status display, through the WebUI, or by the available internal or external LEDs. This system includes:

Status Panel LED Indicators

Projector OSD Status Menu
 Web User Interface Status Page
 Internal PCB-specific LEDs and Main AC status LED
If warnings and errors reported at these locations cannot be resolved by the operator or administrator, further
troubleshooting by a qualified service technician may be required. When troubleshooting, keep in mind that
the projector is comprised of numerous replaceable modules, such as printed circuit boards, optical assemblies
and power supplies. This modular design can reduce the amount of time required to accurately diagnose and
resolve a performance issue — the cause need only be traced down to the module level, at which point the
faulty module is usually replaced. No further analysis is necessary.
