■ Safety Instructions

SAFETY PRECAUTIONS

WARNING:

The chassis of this projector is isolated (COLD) from AC line by using the converter transformer. Primary side of the converter and lamp power supply unit circuit is connected to the AC line and it is hot, which hot circuit is iden- tified with the line ( ) in the schematic diagram. For continued product safety and protection of personnel injury, servicing should be made with qualified personnel.

The following precautions must be observed.

1:An isolation transformer should be connected in the power line between the projector and the AC line before any service is performed on the projector.

2:Comply with all caution and safety-related notes provided on the cabinet back, cabinet bottom, inside the cabinet or on the chassis.

3:When replacing a chassis in the cabinet, always be certain that all the protective devices are installed

DO NOT OPERATE THIS PROJECTOR

WITHOUT THE PROTECTIVE SHIELD

IN POSITION AND PROPERLY SECURED

4:Before replacing the cabinet cover, thoroughly inspect the inside of the cabinet to see that no stray parts or tools have been left inside

Before returning any projector to the customer, the service personnel must be sure it is

properly, such as, control knobs, adjustment covers

completely safe to operate without danger of

or shields, barriers, etc.

electric shock

PRODUCT SAFETY NOTICE

Product safety should be considered when a component replacement is made in any area of the projector.

Components indicated by mark in the parts list and the schematic diagram designate components in which safety can be of special significance. It is, therefore, particularly recommended that replacement of there parts must be made by exactly the same parts.

SERVICE PERSONNEL WARNING

Eye damage may result from directly viewing the light produced by the lamp used in this equipment. Always turn off lamp before opening cover .The Ultraviolet radiation eye protection required during this servicing.

Never turn the power on without the lamp to avoid electric-shock or damage of the devices since the stabilizer generates high voltages (15kV-25kV) at its starts.

Since the lamp is very high temperature during units operation replacement of the lamp should be done at least

45 minutes after the power has been turned off, to allow the lamp cool-off.

DO NOT ATTEMPT TO SERVICING THE REMOTE CONTROL UNIT.

Laser Beam may be leaked out when in disassemble the Unit. As the Laser Beam used in this Remote control unit is harmful to the eyes.

Attention for handing

 Do not touch the lamp until it has cooled completely, because the lamp is very hot during operation and immediately after turned off.

 The lamp has to be fixed firmly to the base or socket.

 Turn off the power supply during maintenance.

 Do not hold the lamp except outer surface of the reflector.

 Wear protective gloves and eyeglasses when handling the lamp.

 Any unusual shock or vibration to the lamp should be avoided.

 The lamp contains the mercury. Its breakage might cause mercury to flow out of the reflector. Please manage provision at the customer’s product.

 Do not pull the lead wire and plug by more than 24.5N.

 Please be careful of handling the lamp because it is made of glass.

 Please notice for keeping or handling the lamp, because there is a projection of this lamp with reflector ahead.

 Do not touch the bulb and the mirror area of the reflector.

Attention for use

 Do not close or cover the lamp with any flammable stuff.

 During operation, the lamp is under extremely high pressure. Please manage provision at the customer’s product to prevent fragments of bulb and mercury from flowing out of it. If the lamp bursts in case of an emergency, the sound will be occurred.

 Lamp operation should be with the specified lamp driver and the system only.

 Do not look at the lamp directly during operations.

 Do not expose your skin directly. We recommend to you to put on something for protection for your skin. For example, long sleeve shirt, gloves, glassed and so on.

 Do not modify the lamp and never use a lamp that has been modified.

 Any unusual shock or vibration to the lamp should be avoided during operation.

 Do not use any broken lamps.

 Dispose of used lamps according to your local instruction.

 Do not turn on the lamp while the system is opened.

 The lamp contains mercury. If the lamp bursts during operation ventilate the area sufficiently to avoid inhaling harmful mercury fumes.

 Use the lead below 200℃ to prevent a deterioration of cladding clad of the fluorocarbon resin.

 The lead wire insulation clad shouldn’t touch the reflector.

 Exchange the lamp that has already passed the life time immediately.

3.2 Disassembly Procedure

Warning



Put on the Static Electricity Ring when starting for repair.



Repair Environment suggest in Clean-room class 10000. Do not remove Optical

Engine or DMD panel outside the clean room. Please return the optical engine to supplier if your repair condition can not meet the requirement.



While screwing or unscrewing screws, please keep the screwdriver straight. Keeping screwdriver inclined will damage the screw holes.



Please turn off the power before replacing any parts.



Please wait for the projector lamp cooling down and turn off the power before changing it. Never touch or hit the lamp module when replacing the lamp.



When you replace the projector lamp, never touch the new lamp with your bare hands.

The invisible residue left by the oil on your hands may shorten the lamp life. Use lint-free gloves or finger cots are recommended.

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 problems 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 lamp using hours

(2) Confirm LED indicator

The Status Indicator Panel on top of the projector indicates the state of the projector and can help you troubleshoot.

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.
