4. Notes on service
4. 1. Before service operation
4. 1. 1. Light source
1. The light source of the projector uses lasers.
LD(Laser) unit that is mounted on the inside of the light source unit is classified in Class 4 of the safety standards.
• Laser light is very danger, can damage the human eye and skin.
• Please do not perform energization in the state where the lighting block was disassembled.
2. Depending on the operating environment temperature, the luminance of the light source will decrease.
• The higher the temperature becomes, the more the luminance of the light source decreases.
3. The luminance of the light source (LD units) will decrease by duration of usage.
• The time until when the luminance of the light source decreases by half differs depending on the setting of the [PROJEC-
TOR SETUP] menu → [OPERATION SETTING] → [OPERATING MODE].
• The estimated time until when the luminance of the light source decreases by half is as follows.
(The time is estimated when the [PICTURE] menu → [DYNAMIC CONTRAST] is set to [3].)
OPERATING MODE
Estimated time
NORMAL
Approx. 20 000 hours
ECO
Approx. 24 000 hours
LONG LIFE1
Approx. 43 000 hours
LONG LIFE2
Approx. 61 000 hours
LONG LIFE3
Approx. 87 000 hours
• These times are rough estimate when the projector is used without changing the [OPERATING MODE] and [CONSTANT
MODE] settings, and will vary depending on individual difference and usage condition.
4. Static electricity or electrical surges will reduce and degrade the reliability of LD unit.
• When working with the LD unit take countermeasures to avoid the generation of static electricity, Use or wear appropriate
work clothes, gloves, shoes, grounded wrist straps and other tools to avoid static electricity.
4. 1. 2. DMD chip
1. The DMD chips are precision-made. Note that in rare cases, pixels of high precision could be missing or always lit.
• Note that such phenomena do not indicate malfunction.
2. Directing a high-power laser beam onto the projection lens surface can damage the DMD chips.
4. 1. 3. Air filter unit
1. Make sure that the air filter unit is properly attached before using the projector. If it is not properly attached, the projector
will suck in dirt and dust causing a malfunction.
2. The cleaning and replacement cycle of the air filter unit varies depending on the usage
environment.
3. Replace the air filter unit if it is damaged or if the dirt does not come off even after
washing.
