Solution
• Check if all wire units between the Formatter Interface Board and the three
formatter boards are not damaged. A damaged wire unit can cause a short circuit
in the local power supply of the Formatter Interface Board.
• Check if none of the pins of the connectors on the FIB or formatter boards are
bend over.
• Replace the Formatter Interface Board.
• If the problem remains contact Barco for further instructions. The formatter boards
are malfunctioning and have to be replaced at the factory.
