OPEN
Replace
POWER UNIT CIRCUIT.
Execute the following procedure step by step:
1. Check external air temperature and altitude
2. Check that intake vent/exhaust vent are 50cm or more away from surrounding wall.
3. Check if intake vent is clogged.
→If it is dirty, clean it by using a vacuum cleaner.
4. Replace a faulty part

Replace internal air temperature sensor.
[2:2]: External temperature error
Replace external air temperature sensor.
[2:3]: LD temperature error
Are there any damages on heat pipes?
Is light source in failure?
Are there any problems with wiring of LD temperature sensor and MAIN PCB?
→If not, replace LD temperature sensor.
[2:4]: Phosphor wheel temperature error
Is light source in failure?
Are there any problems with wiring of phosphor wheel temperature
sensor and MAIN PCB?
→If not, replace phosphor wheel temperature sensor.
