GPR, Sectional, Mirror side blank or garbled after replacing MLC

Potential Symptoms

  • Mirror face is blank or garbled after replacing MLC (Multi Line Controller).
  • One side blank, the other side (primary side) is playing regular content.

Environment

  • Product: GalaxyPro Revolution (GPR), M4 controller based product
  • Component: MLC
  • Control System: Venus 1500

Cause

  • It takes a minute for the MLC to accept the translation table from the controller on the primary side.

Resolution

  1. Turn the power to the entire display off.
  2. Wait a good minute or so, then turn the power back on. Let the display boot up fully (about 3 minutes).
  3. If there is still an issue, repeat step 1.
    • It is important to make sure the ribbon cables and fiber are plugged into the correct locations (same as it was on the old MLC).
