Lamp Replacement.

1. Turn off the projector and disconnect the AC cord. Allow the projector to cool for at least 45 minutes.
2. Loosen 1 screws with a screwdriver and open the lamp cover.
3. Loosen 2 screws and pull out the lamp assembly by grasping the handle.
4. Replace the lamp assembly securely and tighten 2 screws.
5. Close the lamp cover and tighten 1 screw.
6. Connect the AC cord to the projector and turn on.
7. Reset the Lamp Replace Counter, see below explanation

Note: Do not reset the Lamp Replace Counter, except after lamp is replaced.

The projector can not be turned-on with lamp cover removed, because when the lamp cover is removed, the interlock switch is also released to switch off the mains power for safety.

How to reset Lamp Replace Counter.

• Turn the projector on, and press the MENU button and the on-screen menu will appear. Press the ◄/►  button to move a red frame pointer to SETTING menu icon.
• Press the ▲  button to move a red frame pointer to “Lamp counter reset” and then press the SELECT button. The message “Lamp replace counter reset?” is displayed. Move the pointer to [Yes] and the press the SELECT button.
• Another confirmation dialog box appears and select [Yes] to reset Lamp Replace Counter.

How to check Lamp Replace Counter.

The LAMP REPLACEMENT indicator will illuminate when the Lamp Replace Counter reaches 1000 hours. This is to indicate that lamp replacement is required.

• Press and hold the pointer ▲ on the projector for more than 20 seconds.
• The Lamp replace Counter is displayed on top left corner of the screen briefly.

Circuit Protections

This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the projector, it will automatically turn off by operating one of the following protection circuits.

Fuse

The fuse is located inside of the projector. When either the LAMP indicator or the READY indicator is not illuminated, fuse may be opened. Check the fuse as following steps.  It should be used the specified fuse as follows;

Remove the cabinet top following to “Mechanical Disassemblies”.

Remove the fuse from fuse holder.  To install the fuse, take reversed step in the above. [TYPE 8A 250V FUSE]

Thermal switch

There is the thermal switch (SW905) inside of the projector to prevent the internal temperature rising abnormally. When the internal temperature reaches near 90˚C, turn off the AC main power supply automatically.

The thermal switch is not reset to normal automatically even if the internal temperature becomes normal. Reset the thermal switch following procedure.

Check the resistance between terminals of thermal switch by using the tester. If it has high impedance, thermal switch may be in operative.

How to reset the thermal switch

Remove cabinet top following to the “Mechanical Disassemblies”.

Press the reset button on the thermal switch.

CAUTION: Before press the reset button, make sure that the AC cord must be disconnected from the AC outlet.

Interlock switch

The interlock switch (SW902) cuts off the AC mains power supply when the lamp cover is removed. After opening the lamp cover for replacing the lamp ass’y, place the lamp cover correctly otherwise the projector cannot turn on.

CONTRAST ADJUSTMENT

• Before adjustment, input a 100% of Black Raster Signal.

R G B Contrast Adjustment

1. Loosen the screw on the polarized glass mounting base which  intended to adjust.
2. Turn the polarized glass mounting base to obtain the darkest brightness on the screen.
3. Tighten the the screw to fix the polarized glass mounting base.

Condenser Lens Adjustment

1. Turn the projector ON by a state of without FPC cables.  
2. Adjust the adjustment base of condenser lens assembly to make color uniformity in white.  If the shading appears on the left or right of the screen, loosen two fixing screws with 2.0 mm hex driver, and adjust the slot to make color uniformity in white by using the slot screw driver.  If shading appears, on the top or bottom of the screen, loosen screws [2nos] with 2mm hex driver and adjust the slot to make color uniformity in white by using a slot screwdriver.  
3. Tighten all screws to fix the condenser lens unit.  The relay lens adjustment must be carried out after this adjustment.

Relay Lens-Out Adjustment
