SAFTY PRECAUTIONS
During servicing carefully observe the following.
1. OBSERVE ALL PRECAUTIONS
Items and locations that require special care during serv­icing, such as the cabinet, chassis, and parts are labelled with individual safety instructions. Carefully comply with these instructions and all precautions in the instruction manual.
2. BE CAREFUL OF ELECTRIC SHOCK
The chassis carries an AC voltage. If you touch the chassis while it is still alive, you will get a severe shock. If you think the chassis is alive, use an isolating transformer or gloves, or pull out the plug before replacing any parts.
3. USE SPECIFIED PARTS
The components have been chosen for minimum flammability and for specific levels of resistance value and withstand voltage. Replacement parts must match these original specifications. Parts whose specifications are particularly vital to safe use and maintenance of the set are marked on the circuit diagrams and parts list. Substitution of these parts can be dangerous for you and the customer, so use only specified parts.
4. REMOUNT ALL PARTS AND RECONNECT ALL WIRES AS ORIGINALLY INSTALLED
For safety, insulating tape and tubes are used throughout, but some lift-off parts on the printed wiring board require special attention. All wires are positioned away from high-temperature and high-voltage parts, and, if removed for servicing, they must be retuned precisely to their original positions.
5. LAMP
Be very careful of the lamp because it generates high heat while it is used at high voltage. When replacing the bulb, make sure it is cool enough.
6. LENS
Do not look into the lens during projection. This important to avoid damage to the eyes.
7. SERVICING
At the time of repair or inspection services, use an earth band (wrist band), without fail.
8. RUN A COMPLETE SAFETY CHECK AT THE COMPLETION OF SERVICING
After completion of servicing, confirm that all screws, parts, and wiring, removed or disconnected for servicing, have been returned to their original positions. Also examine if the serviced sections and peripheral areas have suffered from any deterioration as a result of servicing. In addition, check insulation between external metallic parts and blades of wall-outlet plugs. This examination is indispensable in confirming complete establishment of safety.
(Insulation check) Pull out a plug from a wall outlet to disconnect the connection cable. Then turn on the POWER switch. Use a 500V megger (Note 2) and confirm that the insulation resistance is 1M or more between each terminal of the plug and exposed external metal (Note
1). If the measured value is below the specified level, then it is necessary to inspect and fix the set.
(Note 1)
Exposed external metal....RGB input terminals, control
terminals, etc. (Note 2) If a 500V megger is not available for an unavoidable reason, then use a circuit tester or the like for inspection.

This section describes how to set up your MultiSync VT440/VT540 projector and how to connect video and audio sources.
Setting up Your Projector
Y our MultiSync VT440/VT540 Projector is simple to set up and use. But before you get started, you must first:
1. Determine the image size.
2. Set up a screen or select a non-glossy white wall onto which you can project your image.
Carrying the Projector: Always carry your projector by the handle. Ensure that the power cable and any other cables connecting to video sources are disconnected before moving the projector.
When moving the projector or when it is not in use, cover the lens
with the lens cap.

Selecting a Location
The further your projector is from the screen or wall, the larger the image. The minimum size the image can be is approximately 25" (0.64 m) measured diagonally when the projector is roughly 4 feet (1.2 m) from the wall or screen. The largest the image can be is 300" (7.6 m) when the projector is about 39.3 feet (12.0 m) from the wall or screen.
Using a Tabletop or Cart
1. Place your projector on a flat level surface at the optimal distance from the screen or wall so you realize the size image you want. (Avoid having bright room lighting or sun light directly on the screen or wall where you’ll be projecting the image.)
2. Connect the power cable, remove the lens cap and turn the projec­tor on. (If no input signal is available, the projector will display a background image.)
3. Ensure that the projector is square to the screen.
4. Move the projector left or right to center the image horizontally on the screen.
5. To center the image vertically, lift the front edge of the projector and press the One-Touch Tilt button on the front side of the pro­jector to release the Front Adjustable foot.

WARNING
• Installing your projector on the ceiling must be done by a quali­fied technician. Contact your NEC dealer for more informa­tion.
* Do not attempt to install the projector yourself.
• Only use your projector on a solid, lev el surface. If the projec­tor falls to the ground, you can be injured and the projector severely damaged.
• Do not use the projector where temperatures vary greatly . The projector must be used at temperatures between 32˚F (0˚C) and 95˚F (35˚C).
• Do not expose the projector to moisture, dust, or smoke. This will harm the screen image.
• Ensure that you have adequate ventilation around your pro­jector so heat can dissipate. Do not cover the vents on the side or the front of the projector.

This section describes the simple maintenance procedures you should follow to replace the lamp, clean the filter, and replace the batteries in the remote control.
Replacing the Lamp
After your lamp has been operating for 2000 hours (up to 3000 hours in Eco mode) or longer, the “Status” light in the cabinet will go on and the message will appear. Even though the lamp may still be work­ing, replace it at 2000 (up to 3000 hours in Eco mode) hours to main­tain optimal projector performance.
CAUTION
• DO NO T TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off, wait a full minute, and then disconnect the power cable. Allow at least one hour for the lamp to cool before handling.
• DO NOT REMOVE ANY SCREWS except the lamp cover screw and three lamp case screws. You could receive an elec­tric shock.
The projector will turn off and go into stand by mode after 2100 (up to 3150 hours in Eco mode) hours of service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 2000 hours (up to 3150 hours in Eco mode) of use, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as the pieces of glass may cause injury. If this happens, contact your NEC dealer for lamp replacement.
To replace the lamp:
1. Loosen the lamp cover screw until the screwdriver goes into a freewheeling condition and remove the lamp co ver. The lamp cover screw is not removable.

Hold it between your thumb and index finger, and start cleaning the lens at the center and circle the cloth or paper toward the edge, wiping off foreign matter out to the edge. Do not apply pressure on the lens surfaces while cleaning.
(2) Mirror Cleaner
Never grip the mirror hard because it is vapor-deposited. Minor stains may be removed by dissolving them with alcohol and wiping off dry.
(3) Point
Stains on both sides of the LCD unit and on the LCD side of the field lens degrade the picture. Keep them clean.

CIRCUIT DESCRIPTION

3. Outline hardware description
3-1 RGB video signal
This signal output is generated from the signal processing circuit G/A, UNI2 (IC3601), on the main board (MAIN PWB). Each 10-bit R,G,B digital video signal (3.3Vp-p) is processed for 6/12 (SVGA/XGA) phase decode processing by the phase decoding ICs (IC3701, 3702, 3703, 3704, 3705, 3706), and also for the level adjustment (10.0Vp-p (2.0V/12.0V)) by the serial D/A (IC3711). Since then, each signal is fed to the LC panel through the LC driver boards (LCES PWB/ LCEX PWB).
3-2 Panel driving signal
This signal output is generated from the signal processing circuit G/A, YAMAG (IC3701), on the same main board (MAIN PWB). The panel drive timing signal (3.3Vp-p) is processed for level shifting to the level (15.5Vp-p) required to drive the shift register in the LC panel by the aid of the level shift ICs (IC5201, 5202, 5203/ IC6201, 6202, 6203) located on the LC driver boards (LCES PWB/ LCEX PWB). Since then, the processed signal is fed to the LC panel.
3-3 Panel auxiliary signal
This signal output is generated from the LC panel signal processing circuit G/A, YAMAG (IC3701), on the same main board (MAIN PWB). The panel auxiliary signal (3.3Vp-p) is processed for level shifting to the level (5.0Vp-p, (2.5V/7.5V)) required to pre-charge the video line in the LC panel by the aid of the level shift ICs (IC5201, 5202, 5203/ IC6201, 6202, 6203) located on the LC driver boards (LCES PWB/ LCEX PWB). Since then, the processed signal is fed to the LC panel via the diamond buffer of the complex transistor group.

3. I/O PWB block
3-1 RGB OUT circuit
The RGB video signal input entered in Pin 15 of the Mini D-SUB is amplified at the 6dB amplifier (IC4000; AD8013AR) so that it attains 1Vp-p at the time of 75 termination. The H Sync output is generated through the buffer circuit (Q4000 to Q4002). The V Sync output is in the THROUGH OUT.
3-2 Plug & Play
The V Sync terminal of Pin 15 of the Mini D-SUB and the serial terminal of Pins 12 and 15 are connected to the Plug & Play IC (IC4001: 12LC21T) so that the projector can be detected at the PC.
4. MAIN PWB block
4-1 Video signal processor block
The composite video signal passes through the 6dB amplifier (IC1100; MM1031XM) and the low-pass filter (FL1113), and enters Pin 41 of the video decode IC (IC1104: CXA2139S) at 1Vp-p. The NTSC and PAL signals are led to the IC’s internal SW and 6dB amplifier, and the resultant output is fed to Pin 6. The signals are further sent to the 3-line Y/C separator circuit (IC1101: TC9090AF). The signals from Y/C separation are returned again to the video decode IC. The composite SECAM signal and the B/W signal do not pass through the 3-line Y/C separator circuit. The composite SECAM signal is processed for Y/C separation by the BPF & TRAP that is incorporated in the video decode IC. The SF video input signal is directly entered in the video decode IC. The result of discrimination for the color system, vertical frequency, etc., to be conducted at the video decode IC is supervised by the CPU through the I2C bus. According to this result, the CPU controls the 3­line Y/C separator IC and the video decoder at the appropriate setting values through the I2C bus. In the video decode IC, the sharpness control and the compensation for the phase in conjunction with the chroma output signal are carried out for Signal Y. The signal decoded (decoding angle = 90ÅB) to the Y/ chroma in the video decode IC is entered in the A/D converter IC (IC3401: CXA3506R). The sync signal contained in the Y signal selected by the switch of the video decode IC is sent as the H·V timing pulses to the sync signal changeover block (IC3301: YAMAG) at the next stage, through the hori­zontal and vertical sync separator circuit in the IC, the copy guard signal mask circuit, the AFC circuit, IC’s external mono-multi circuit, etc.
CIRCUIT DESCRIPTION
4-2 Sync signal processor block (Mini D-SUB 15-pin input)
The sync signal input entered in Pin 15 of the Mini D-SUB is sent to the amplitude limiter circuit. In this amplitude limiter circuit, the H/V sync signal limited to 0.6Vp-p is applied to the sync signal processor IC (IC1006: M52347FP). In order to cope with the sync attenuation signals, the Sync on Green signal input is entered in the sync signal processor IC via the Sync chip clamp circuit and the AMP circuit. The DVD signal only is entered in Pin 43 of the video decode IC via IC1001, so that sync processing is conducted in the same manner as for the video signals. In the sync signal processor IC, the following processing is carried out:
• Discrimination of the presence of H/V Sync
• Discrimination of the polarity of H/V Sync
• Sync separation for the composite Sync
• Sync separation for the G-Sync
• Generation of clamp pulses
• H/V Sync output The result of discrimination is read out at the serial D/A (IC1003: CXA1315) and sent to the CPU. The H/ V Sync output is sent to the Sync signal changeover block (IC3301: YAMAG). After the completion of output synchronization and selection for the video decode IC, the H sync signal is sent to the A/D con­verter IC (IC3401: CXA3506R) and the V sync signal is sent to the signal processor IC (IC3502: En­deavor).

CIRCUIT DESCRIPTION
4-3 RGB/Component signal processor and A/D converter block
The video signal input entered in Pin 15 of the Mini D-SUB is fed to the A/D converter IC (IC3401: CXA3506R) through the buffer circuit. In the case of a component signal, only the chroma signals (Pb, Pr, Cb, Cr) are entered after their levels have been lowered at the attenuator of -6B. In the A/D converter IC, the video signal from the video decode IC or the video signal at Pin 15 of the Mini D-SUB is selected. After the contrast has been adjusted at the built-in analog amplifier, this signal is processed for A/D conversion into the 8-bit digital signal. The 8-bit digital signal is entered in the signal processor IC (IC3502: Endeavor) for signal processing. The signal to be used to clamp the video signal (clamp pulses) is the clamp pulse signal from the sync signal processor IC (IC1006: M5234FP) or the one from the signal processor IC (IC3502: Endeavor) chosen by the changeover action at the signal changeover block (IC3301: YAMAG). This signal is then entered in the A/D converter IC (IC3401: CXA3506R) for signal clamping. Generally for the VIDEO and HD signals, the clamp pulses of the signal processor IC are used. For the RGB signals, the clamp pulses of the sync signal processor IC are generally used.
4-4 Audio signal processing
The audio signal passes through the buffer circuit of the MAIN PWB, and is then fed to the output AMP IC (IC4100: AN7512SH) that is incorporated in the VOLUME control of the KEY PWB. The VOLUME control is effected at the serial D/A (IC1003: CXA1315). The amplified audio signal is output (MAX: 1W) to the speaker system (8W x 1).
