CAUTIONS BEFORE STARTING SERVICING
Electronic parts are susceptible to static electricity and may easily damaged, so do not forget to take a proper grounding treatment as required. Many screws are used inside the unit. To prevent missing, dropping, etc. of the screws, always use a magnetized screwdriver in servicing. Several kinds of screws are used and some of them need special cautions. That is, take care of the tapping screws securing molded parts and fine pitch screws used to secure metal parts. If they are used improperly, the screw holes will be easily damaged and the parts can not be fixed.

< How to mount a new LCD > 1. When mounting a red LCD, mount it on the red LCD plate (No.23796019) or when mounting a blue LCD, mount it on the blue LCD plate (No.23796018) so that the FPC section faces upward and main unit side faces downward. 2. When mounting a green LCD, mount it on the LCD plate used so far. In this case, prepare the green LCD mounting jig (No.23796021), and position the LCD plate so that its two holes (1) matches two protruded parts on the jig. Then place the green LCD on it in the same direction as the red and blue LCDs by tightening screws (3 holes (2) on the LCD plate). Note: · Be always sure to attach the black shielding sheet on the LCD.

Fig. 3-2-5 < Drive PC board remounting > Remount the drive PC board under the filter cover not installed. Connect cables removed from connectors on the drive PC board and the LCD panel as they were connected. (If a signal generator which can not generate a white raster signal is not available, do not connect the LCD panel.)
< Setup > 1. Make a wall chart on white fiber board as illustrated in Fig. 3-2-6. Note:
(1) LCD plate mounting holes Green LCD plate
· Only use a stiff material to prevent focus errors.
812.8mm (12")
Fig. 3-2-4 3. Mount the LCD plate with a new LCD mounted at the bottom side of the LCD block (can be mounted only in one direction) and tighten the screws. Do not tighten the screws completely. Tighten the screws temporarily so that the LCD can move for later pixel matching adjustment of the LCDs. Note: · Do not mount the filter cover to allow the LCD adjustment. Fig. 3-2-6 < Adjustment of LCD > If the red and blue LCD panels need to be adjusted, follow the procedures in the item "Red/Blue LCD adjustment". However, if the green LCD panel needs to be adjusted, follow the procedures in the item "Green LCD adjustment". After the green LCD panel adjustment is carried out, it is necessary to replace or adjust the red and blue LCD panels as described in the item "Red/Blue LCD adjustment". 2. Retract the foot adjusters so the unit sits flat. 3. Place the LCD Projector on a table so that the front edge of the lens is 1.45m from the wall. (Refer to Fig. 3-2-6) 4. Set the zoom ring to the maximum wide setting. 5. Adjust the focus ring to the center of its range.
609.6mm (24") 1.45m (57") 92mm

6. Feed a white raster signal through RGB connectors and turn on the power of the projector. (If a signal generator which provides a white raster signal is not available, turn on the power without connecting the LCD panel.) 7. If all three LCD panels need to be replaced, refer to the "Green LCD adjustment". 8. Adjust the focus ring and the raster focus of the LCD which has not been replaced. If the green LCD is not replaced, adjust the green raster. If the green LCD is replaced, adjust the red raster, and if the red LCD is replaced, adjust the blue raster. 9. Atach the wall chart to the wall so the bottom line of the square lines up with the bottom of the raster. Also, center the chart horizontally with the raster. 10. Adjust the zoom ring and make sure the bottom of the raster remains on the bottom line. Return the zoom ring to the maximum wide setting. 11. Hereafter, do not move the setting position and the focus ring.
5. If the focus or raster geometry is changed, when tightening the screws holding the LCD mount, loosen the screws slightly and readjust. 6. Prepare one focus adjustment jig and insert it onto the one hole on top of the LCD plate, and adjust the LCD plate back and forth until the best focus is obtained in considering upper and lower balance of the projection screen. (Refer to Fig. 3-2-7.) 7. If the focus or raster geometry is changed, when tightening the screws holding the LCD mount, loosen the screws slightly and readjust. 8. Input the cross hatch pattern of G signal. 9. Adjust the cross hatch pattern up & down (Refer to Fig. 3-2-8) and left & right (Refer to Fig. 3-2-9) with the three adjusting screws (hex screw driver (1.0 mm) available on the market) until it is aligned with the green cross hatch pattern.
< Red/Blue LCD adjustment > 1. Confirm connection of the LCD panel (if not connected, connect the LCD to the connector of the PC board.) 2. Turn the projector on. 3. Input the cross hatch pattern from RGB connectors. Only input R signal when adjusting the red panel focus, and only input B signal when adjusting the blue panel focus. 4. Prepare two focus adjustment jigs. Insert them onto two holes on bottom of the LCD plate, and adjust the LCD plate back and forth until the best focus is obtained in considering left and right balance of the projection screen. Fig. 3-2-8
Fig. 3-2-9 10. Turn off the power, and remove the FPC section of the LCD from the connector of the drive PC board.
Fig. 3-2-7

11. Fill a quick dry adhesive at joint of the LCD mount. In this case, sufficient care will be necessary so that the adhesive does not stick to the LCD panel surface or any other parts. Note: · Use the adhesive available on the market as an epoxy type two liquid mixture of equal amount.
Adhesive filling hole
12. Leave the LCD block until the adhesive is hardened for a required time. In this case, place a thin paper on the LCD block to prevent dusts from entering. 13. When the adhesive is hardened, connect the FPC of the LCD to the connector of the PC board, and turn on the power. Check to see pixel deviation of the LCD. 14. Check to see dusts of the LCD. If dusts are found, remove them. 15. Turn the power off. Remove all the cables connected to the PC board and LCD panel, and remove the drive PC board. 16. Mount the filter cover removed again. Tighten 4 screws, and close openings around the FPC section with tape. 17. Mount the drive PC board again. Connect cables disconnected from the drive PC board and the LCD panel as they were connected. 18. Turn on the power and check operations.

< Green LCD adjustment > 1. Confirm connection of the LCD panel (if not connected, connect the LCD to the connector of the PC board.) 2. Turn the projector on. 3. Input the cross hatch pattern from the RGB connectors. Adjust the green color only. 4. Prepare two focus adjustment jigs. Insert them onto two holes on bottom of the LCD plate, and adjust the LCD plate back and forth until the best focus is obtained in considering left and right balance of the projection screen. (Refer to Fig.3-2-7.) 5. If the focus or raster geometry is changed, when tightening the screws holding the LCD mount, loosen the screws slightly and readjust. 6. Prepare one focus adjustment jig and insert it onto the upper hole of the LCD plate, and adjust the LCD plate back and forth until the best focus is obtained in considering upper and lower balance of the projection screen. (Refer to Fig.3-2-7.)
7. If the focus or raster geometry is changed, when tightening the screws holding the LCD mount, loosen the screws slightly and readjust. 8. When the green LCD is replaced, the pixel matching adjustments for the red and blue panels will be necessary in many cases. (If the pixel matching is obtained in above adjustment, it is not necessary.) Accordingly, turn off the power. Remove the FPC section of the red and blue LCDs from the PC board connectors, and remove the red and blue LCD plate from the LCD block. 9. Remove the red and blue LCD from the LCD plate and mount them on new LCD plates. 10. Mount the new red and blue LCD plates on the LCD block. 11.

1-6. Waveform and Voltage Measurement
· Measurement of waveform and voltage at each section in the color circuits was conducted with sufficient service color bar signal being received and reproduced in normal conditions. · Waveforms and voltage values for the remaining circuit were measured with a broadcasting signal normally received, so they may vary slightly according to the programs being received. Use them as a measure for servicing. · All voltage values except the waveforms are expressed in DC and measured by a digital voltmeter. 3. If it is difficult to remove the part, temporarily stop the desoldering job and wait until temperature of the part lowers. Then, repeat steps 1 and 2. 4. Form leads of the replacement part (general part equivalent to the chip part) as shown in the figures and solder place. (Fig. 1-7-2)
