■ Optical Adjustment
Before taking optical adjustments below, remove the Cabinet Top and Main Board following to the “Mechanical
Disassemblies”
Adjustments require a 2.0mm hex wrench and a slot screwdriver. When you adjust Integrator lens or Relay lens
adjustment, you need to disconnect some connectors and FPC cables of LCD panels on the main board.
Note:
1. Do not disconnect connectors K56M, K56N, K48K, K8E, K8H, K66A, K66B, K66C, K66D and K66F on the main
board, because the projector can not turn on or operate properly for adjustment.
2. In case of adjusting without the cabinet top, the setting for Fan Control is needed specially as shown below.
(Refer to “Electrical Adjustment” to enter the service mode and adjust.) After servicing, set to previous data.
Adjustment Item: No. 51
Adjustment Data: “0” (With Cabinet Top) ➞ “1” (Without Cabinet Top)
