1 SERVICE CAUTIONS AND NOTES

1.1. SERVICE POSITION

Because of this projector’s structure, service should be provided by turning this projector over, accordingly the screens are seen reversely during the service.

The position shown in Fig. 1-1-2 is used for checking, adjusting and replacing parts. Extension Cable (Extension cable is the same as the Extension Cable Kit [BHY40001] of the LX-D300/LX-D350 service jigs.) is necessary for servicing as shown in Fig. 1-1-1.

*Extension cables may be slightly different in shape.

Fig. 1-1-1

1. In the order described in the “2.2. Disassemb ly Method of Cabinet Parts” of “2. Disassembly/Assembly Procedures”, remove the Bottom Case Unit.

2. Remove the Joint Plate L, R and Ballast Holder as shown in Fig. 2-2-7.

3. Disconnect connectors P1901, P1902, P2002-P2004 and P3501-P3503 on the Main PWB as shown in Fig. 2-2-8. a. Connect Extension Cables as follows: b. Connect Extension Cable-1 (30 pin) between P3501 on

the Main PWB and the LCD Red Unit.

c. Connect Extension Cable-1 (30 pin) between P3502 on

the Main PWB and the LCD Green Unit.

PWB for over 5 seconds as shown in Fig. 1-2-1.

1.3. How to initialize EEPROM IC

If EEPROM IC (IC2006) on Main PWB are replaced: After replacing EEPROM IC (IC2006), be sure to perform each of following steps in the order presented.

1. Connect a jumper wire between TP2017 and TP2018 on Main PWB for over 5 seconds to set to factory set mode. Then, remove the jumper wire.

2. “FACTORY” appears on screen.

3. Connect a jumper wire between TP2017 and TP2018 again for ov er 5 seconds to initializ e EEPROM IC. Then, remove the jumper wire.

4. “SELF CHECK” appears on screen.

5. Remove jumper wires and “MEMORY OK” appears on screen.

6. Perform adjustments 3.4.1. through 3.4.8., 3.4.11. and 3.4.12.

7. After completing all adjustments, press the MENU button to memorize adjustment data in EEPROM IC and release from the Factory Adjust mode. Otherwise, adjustment data will be cancelled.

Note:

When initializing EEPROM IC, memory data such as history of lamp operation time and adjustment data will be reset.

Fig. 1-2-1

5. Lamp operation time will be displayed as shown in Fig. 1-2-2. (As the set is turned upside down, actually the screen also looks upside down.)

Fig. 1-2-2

6. Connect a jumper wire between TP2007 and TP2008 for over 5 seconds again or press MENU button on remote control in order to release from service mode.

Note:

After replacing Main PWB, memory data such as history of lamp operation time will be reset. How ever, it can be remained by installing EEPROM IC (IC2006) to replaced Main PWB from original Main PWB.
