LAMP

of the LCD Backlight Lamp, which is recommended at approximately

 

10,000 hours of operation, or if the display becomes dim.

 

 

NOTE

 

 

The front panel assembly does not have to be removed.

 

Preliminary:

 

￿ Switch 373XXA power off. Remove the power cord.

 

￿ Remove all covers (paragraph 8-3).

 

Remove/Replace Procedure:

 

Step 1.

Remove the LCD assembly (paragraph 8-10).

 

Step 2.

Remove the Backlight Lamp cover as follows:

 

 

On Sharp LQ9D169 LCD displays, remove the three Phil-

 

 

lips screws on the side opposite the PCB, then lift off the

 

 

cover.

 

 

On Sharp LQ9D340 LCD displays, on the side opposite the

 

 

PCB, remove the tape covering the center catch. Starting at

 

 

one end, very carefully push each catch clear of its tab

 

 

while gently lifting the cover. Release all five catches and

 

 

remove the cover.

 

Step 3.

Carefull replace the Backlight Lamp, while being careful

 

 

not to apply pressure to the area where the glass tube and

 

 

the end caps of the Backlight Lamp meet.

 

Step 4.

Reinstall the Backlight Lamp cover.

 

Step 5.

Reinstall the LCD Assembly and reconnect electrical con-

 

 

nectors.

 

Step 6.

Reinstall the top cover.

 

Step 7.

Turn the instrument on. Adjust the Brightness Potentiome-

 

 

ter at the rear panel for maximum display brightness.
