3. Troubleshooting
Situation
Solution
The supply voltage for the fan which
cools the cathode of the lamp is too
high. The fan for the lamp cathode
cooling is mounted between the
lamp compartment and the input &
communication unit.
Replace the Fan & Motor control board.
Error 7973 : “Fan 1 voltage low”
This error may be preceded by a warning.
Situation
Solution
The supply voltage for the fan which
cools the cathode of the lamp is too
low. The fan for the lamp cathode
cooling is mounted between the
lamp compartment and the input &
communication unit.
Replace the Fan & Motor control board.
Error 7974 : “Ambient temp high”
This error may be preceded by a warning.
Situation
Solution
Blocked high density filter at the
front side of the projector.
Replace the front high density filter with a new one.
Ambient temperature too high.
Check the ambient temperature. Make sure that the ambient temperature does not
exceed 40°C. Be aware that room heat rises to the ceiling.
Error 7976 : “SMPS HS temp high”
Temperature on the heat sink of the secondary circuit of the SMPS unit is too high. This error may be preceded by a warning.
Situation
Solution
Ambient temperature too high.
Check the ambient temperature. Make sure that the ambient temperature does not
exceed 40°C. Be aware that room heat rises to the ceiling.
Blocked front filter.
Replace the high density filter at the front side of the projector with a new one.
Malfunction SMPS module.
Replace the SMPS module.
Error 7978 : “Lamp temp high”
This error may be preceded by a warning.
Situation
Solution
Ambient temperature too high.
Check the ambient temperature. Make sure that the ambient temperature does not
exceed 40°C. Be aware that room heat rises to the ceiling.
Blocked high density filters.
Check all high density filters. Replace filthy high density filters with a new ones.
Obstructed air outlet channel.
Check if the air outlet at the rear of the projector is not covered. There should be at
least one meter of free area at the rear of the projector.
Malfunction lamp anode fan or lamp
cathode fan.
Check the speed and voltage (using the service menu) of the lamp anode fan or lamp
cathode fan. Replace any malfunctioning fan.
Error 7980 : “Blue DMD temp high”
This error may be preceded by a warning.
