Solution
Measure on the Signal Backplane the +24V voltage on pin 9, 10, 11 or 12 of the
connector of the black wire unit which comes from the SMPS board. See image 4-26.
If the measured voltage is about 24V then replace the Fan Control board. See
"Removing a board in the card cage", page 213. Otherwise replace the SMPS board.
See"Replacement of the Switched Mode Power Supply", page 281.
Solution
Replace the SMPS module. See "Replacement of the Switched Mode Power Supply",
page 281.
Check the insulation of the wire unit of the Anode fan. The Anode fan is located below
the compartment of the Light Processor.
1. Repair the insulation of the wire unit using shrink sleeve.
2. If not repairable replace the Anode fan. See "Lamp anode fan", page 324.
Replace the Fan & Motor Control board. See "Removing a board in the card cage",
page 213
Replace the Signal Backplane. See "Replacement of the signal back plane", page 231.
