3 Diagnostics & Troubleshooting
This section outlines the self-test operations, test pattern modes, and troubleshooting
steps used to evaluate the PLRs (PLR605X and PLR615X).
Access the PLR
Both types of PLRs (PLR605Xs and PLR615Xs) are
mounted inside the display cabinets on a mounting
plate.
To remove the PLR, follow these steps:
1. Locate the PLR on the project’s Layout Drawing.
2. Disconnect power to the display.
3. Open a rear-access display by removing the back
sheets; open a front-access display by removing a
module located adjacent to the PLR. Refer to the
display access information in the appropriate display
manual.
4. Disconnect all power and signal cables to the PLR.
Refer to Figure 22 .
5. Loosen the mounting attachment screws, slide the
mounting plate keyholes off the screws, and lift the
plate from the display. Refer to Figure 23 .
Reverse these steps to install a new PLR in the display.
