Inc. EP7155 & EP1691 ver.02 1. COMPLIANCE OF SAFE REPAIR Be sure to read this Service Manual before providing services. In the projector, full consideration is taken to ensure safety for fire, electric shock, injury, harmful radiation, and substance. Therefore, observe the notice described in this Service Manual so that safety is kept when providing services. Moreover, be sure to observe the notice described in the Instruction Manual. Pay attention to the following items during service inspection. 1.1 Cautions during disassembling and assembling 1. This equipment contains parts under high voltage. When making repairs, etc. Be sure to pull out the power plug beforehand to insure safety. 2. Parts may be very hot immediately after use. Make sure the equipment has cooled off sufficiently before carrying out repairs. 3. Make sure that parts and screws and wiring, etc. are returned to their original positions. Tube, tape and other insulation materials have been used for safety reasons. The internal wiring has been designed to avoid direct contact with hot parts or parts under high voltage when using clamps or other tools. 4. The parts used in this device have special safety features such as flame-resistance and anti-voltage properties. When replacing parts, always use parts supplied from the factory. 5. After finishing operations make sure that all parts and wires have been returned to their original position and that there has been no deterioration of the area around the location that was worked on. 6. Be sure to use a grounding strap (wrist band) during repair and inspection. 1.2 Lamp During current conduction, the lamp is in the high-temperature state. In this case, pay careful attention because a high voltage is used. When replacing a lamp, replace it after confirming that the lamp has gotten cold sufficiently. 1.3 Lens Do not look into a lens during projection. This damages your eyes.

Remote Control Parts Important: 1. Avoid using the projector with bright fluorescent lighting turned on. Certain high-frequency fluorescent lights can disrupt remote control operation. 2. Be sure nothing obstructs the path between the remote control and the projector. If the path between the remote control and the projector is obstructed, you can bounce the signal off certain reflective surfaces such as projector screens. 3. The buttons and keys on the projector have the same functions as the corresponding buttons on the remote control. This user’s manual describes the functions based on the remote control.

Inc. EP7155 & EP1691 ver.02 Common problems and solutions These guidelines provide tips to deal with problems you may encounter while using the projector. If the problem remains unsolved, contact your dealer for assistance. Often after time spent troubleshooting, the problem is traced to something as simple as a loose connection. Check the following before proceeding to the problem-specific solutions. • Use some other electrical device to confirm that the electrical outlet is working. • Ensure the projector is turned on. • Ensure all connections are securely attached. • Ensure the attached device is turned on. • Ensure a connected PC is not in suspending mode. Ensure a connected notebook computer is configured for an external display. (This is usually done by pressing an Fn-key combination on the notebook.) Image Problems Problem: No image appears on the screen 1. Verify the settings on your notebook or desktop PC. 2. Turn off all equipment and power up again in the correct order. Problem: The image is blurred 1. Adjust the Focus on the projector. 2. Press the Re-sync button on the remote control or projector. 3. Ensure the projector-to-screen distance is within the 10-meter (33-feet) specified range. 4. Check that the projector lens is clean. Problem: The image is wider at the top or bottom (trapezoid effect) 1. Position the projector so it is as perpendicular to the screen as possible. 2. Use the Keystone button on the remote control or projector to correct the problem. Problem: The image is reversed Check the Projection setting on the Setup menu of the OSD.

Cleaning Carry out cleaning of the main unit and interior when replacing the lamp or making inspections. The glass cleaner used with the following parts is as follows. 1)Cleaning the Projection Lens *When dust and fingerprints, etc. are on the lens surface, use the designated glass cleaner to remove as shown in the figure at the right. For fingerprints and other soiling that are difficult to remove with a dry cloth, use a designated glass cleaner which has been moistened in water and then use a dry cloth to dry it off. *The projection lens surface has a special coating. Do not use detergents or solvents on the surface. 2) Cleaning the Color Wheel Assy *The color filter is made of thin glass. Be very careful when handing the filter. *In case of fingerprints, etc. on the surface, clean in the same way as the projection lens unit as described in item 1). Do not use detergents as this could cause peeling of the color filter. 3) Cleaning the DMD *The DMD surface is glass and can be cleaned. However, avoid scratches as these can have a direct influence on the image. *In case of dust on the DMD surface use an air cleaner ( with a device to prevent static, if possible) to clean off the surface. *In case of fingerprints, etc., add a small amount of water to the designated glass cleaner and wipe off in one direction. Then use the designated dry glass cleaner to wipe off in the same direction. *Do not use absolute alcohol or other substances that could leave streaks after drying. 4) Cleaning the Reflecting Mirror *Be careful not to touch the reflecting mirror. The surface is composed of vapor deposition silver and touching it directly with the hands can lead to burnishing. *Do not clean other than with air. 5) Cleaning the Main Unit *Clean with a soft fuzz-free cloth. In case of severe soiling, use a well-wrung cloth dipped in a neutral agent to remove soiling and then finish with a dry cloth. *Do not clean with thinner, benzene or similar agents as this could lead to deterioration or peeling of paint. *In case of dust in suction or exhaust holes or the interior, disassemble the main unit and use air to remove the dust from the inside.
