2. MAINTAINING THE PROJECTOR IN GOOD CONDITION
1. PREVENTING STATIC ELECTRICAL DAMAGE
•
When disassembling and assembling the projector, always use a grounding strap and a
grounding mat. Furthermore, when replacing electrical circuit components (such as cir-
cuit boards and optical engine), bring the static-proof bag containing the new parts into
contact with a metallic section of the projector before taking out the component from the
static-proof bag.
2. USE OF GENUINE PARTS
•
When replacing the structural components inside the projector (including the lamp assy),
use only replacement parts supplied by EPSON and listed in the projector's Parts List.
•
Use the accessory power cord and interface cable provided with the projector.
3. SAFETY TESTING
The following tests should be carried out on repair parts used in the LCP.
Note: These are simplified tests that can be carried out at a repair centre that is not
equipped with full safety testing equipment.
