3. Troubleshooting
3.2 1692 → 1699 : Formatter related errors
Error 1692 : “Form. PWRGood”
Situation Solution
Formatter “Power Good" signal not
OK. The local power supplies on
the Formatter Interface Board fails.
The orange LED “PWRGood” (ref
A image 3-3 & image 3-4) on the
Formatter Interface Board remains
off.
The status LED’s of the Formatter
Interface Board (FIB) are visible
through the filter grid behind the
front filter. So, you have to remove
the projector front cover and the
front filter first to see the LED’s on
the FIB.
• 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.
