Resolution
Note: Blank (empty) module may be available for some display types.
For Temporary Operation
- If no replacement modules are available, move module to end of signal chain to minimize the visual impact.
- The end of the signal chain is either the right side of a single Galaxy display or the right side of the mirror face on a 2v configuration.
- For displays with PLRs, try to locate bad mods next to each other to minimize outage area.
