3.4 Disassembly Lamp Module

As the projector operates over time, the brightness of the projector lamp gra dually decreases

and the lamp becomes more susceptible to breakage. We recommend replacing the lamp if a

warning message is displayed.

Note:

 The lamp is extremely hot right after turning off the projector. If you touch the lamp, you

may scald your finger. When you replace the lamp, wait for at least 45 minutes for the

lamp to cool down.

 Wear protective gloves and eyeglasses when fixing or detaching the lamp.

 Do not operate the lamp in proximity to paper, cloth, or other combustible material nor

cover it with such materials.

1. Turn off the projector.

2. If the projector is installed in a ceiling mount, remove it.

3. Unplug the power cord.

4. Loosen the screw in the side of the lamp cover and remove the cover.

5. Remove the screws from the lamp module, raise the handle, an d lift out the module.

6. Insert the new lamp module into the projector and tighten the screws.

7. Replace the lamp cover and tighten the screw.

8. Turn on the projector. If the lamp does not turn on after the warm-up period, try reinstalling the

lamp.

9. Reset the lamp hour. Refer to the “Information” menu.

4 Troubleshooting and Verifying the Repair

This chapter provides technicians with electronic background how to maintain the product.

Moreover, you can get the appropriate operation to solve some complicated probl ems of

component repairing and professional problems.

4.1 Troubleshooting

Warning

 Do not directly look into the lens to avoid eyesight damages.

 The projector is equipped with ventilation holes (intake) and ventilation holes (exhaust). Do

not block or place anything near these slots, or internal heat build -up may occur, causing

picture degradation or damage to the projector.

Confirm Software and hardware

(1) Confirm FW version is the latest.

How to enter Engineering Mode?

-Open the Main menu and move the color bar to “Information” item, and then move down

the color bar to “Equivalent Lamp Hours” item, press the direction key following the actions

below:

Right once, left twice, right once; then you will enter the Engineering Mode. )

Note: This FW version is just for reference.

ViewSonic Corporation

Pro8400

25

(2) Confirm LED indicator

Note: Swapping modules that may be defective with others known to be good is generally an ideal way to

find the module responsible for the problem. A failure symptom is rarely caused by more than one module,

so you will not usually need to replace more than one to correct a particular failure. Whatever main board,

ballast, IR board, power board, lamp module or optical engine are all suitable to check by swapping

modules.

8 Maintenance

The projector needs proper maintenance. You should keep the lens clean as dust, dirt or spots

will project on the screen and diminish image q uality. If any other parts need replacing, contact

your dealer or qualified service personnel. When cleaning any part of the projector, always

switch off and unplug the projector first.

Warning:

Never open any of the covers on the projector. Dangerous electrical v oltages inside the projector

can cause severe injury. Do not attempt to service this product yourself. Refer all servicing to

qualified service personnel.

Cleaning the Lens

Gently wipe the lens with lens cleaning paper. Do not touch the lens with your hand s.

Cleaning the Projector Housing

Gently wipe with a soft cloth. If dirt and stains are not easily removed, use a soft cloth damped

with water, or water and neutral detergent, and wipe dry with a soft, dry cloth.

Cleaning the Filter Cover

The filter cover, which is located at the side of the projector, should be cleaned after every 100

hours of use. If it is not cleaned periodically, it can become clogged with dust and prevent the

projector from being ventilated properly. This can cause over heating and damage the projector.

To clean the filter cover:

1. Switch the projector off and unplug the AC power

cord from the wall socket.

2. Remove the filter cover as the

illustration shown.

3. Clean the filter cover.

 To clean the filter cover, you are advised to use a

small vacuum cleaner designed for computers

and other office equipment.

 If the filter cover is torn, replace it.

4. Replace the filter cover.

5. Attach the filter cover.

6. Plug the power back into the projector.
