Replace the failed power supply.
For Temporary Operation
If a spare power supply is not available, swap the failed power supply with another to minimize the visual impact to the display.
Galaxy example: Swap a working power supply from mirror face that is working to the primary face where the failed power supply is located.
Billboard and video example: Swap a working power supply from the corner or edge of the display, one that powers fewer modules.
