Note: Because of the difficulty of removing the LCD panels, cleaning the
LCD panels is beyond the scope of the Limited Servicer Program for all
other models included in this addendum.

Notes:

1.The safety and various description sections must be read in the Main Limited Servicer Maintenance Manual (part code SM-LCD) before attempting any procedures outlined in this addendum.

2.The maintenance procedures for the XV-H37VUA, XV-H37VUA(P) are identical to the XG-E1100U. Therefore, please refer to the Main Limited Servicer Maintenance Manual when maintaining the XV-H37VUA.

HOW TO CONVERGE THE LCD PANELS

For the models XG-NV1U, XG-E1200U, PG-D100U, XG-E3000U, XG-NV2U, XG-NV3XU, XG-NV3XB, and XG-E3500U

Tools and equipment needed:

∙Pattern Generator that can produce a crosshatch pattern (grid pattern)

∙Eccentric Cam Adjustment Wrench. (Sharp Part # 9DASPN-XGNV1U)

∙L-shaped Hex Wrench (Sharp part # 9EQLNC-XGNV1U)

∙Philips Screwdriver

NOTE: Confirm focus before performing the convergence procedure. If pixels are in focus in one area of the screen and indistinguishable in another area, the projector is out of focus. The focus alignment procedure is beyond the scope of the limited maintenance program.

convergence.	Servicer Maintenance Manual before attempting to converge
	the panels.
	1. Connect a pattern generator to the video or RGB (when
	applicable ) input terminals.
	2. Output a crosshatch signal from the pattern generator.
	3. Turn on the projector.
	4. Mentally divide the screen into fourths both horizontally	fig. 3-4
		(Main
	and vertically. Imagine the center four squares as the A zone
		Manual)
	and the outer one fourth (all around the outside edge) as the B
	zone. Look at the grids to determine if the convergence is off.
	You should see only white grid lines on the screen ( a white
	line is the product of separate red, green, and blue lines
	“added together,” or converged over the same area ). If the
	red or blue lines are offset from the green lines ( either
	up/down or left/right ), the convergence is off. The green
	panel is fixed, so mechanical adjustment isn’t possible. If
	any adjustments to the red or blue panels are necessary,
	use green as the reference. If the unit is converged to within
	one pixel in the A zone and one and a half pixels in the B
	zone the unit is converged within specification and adjustment
	is not required.

NOTE: Tightening the screws may cause mis-convergence.

	1.	Remove the lamp cover.	fig. 3
	2.	Remove the screws securing the lamp assembly.	fig. 3
	3.	Pull the lamp assembly out of the projector.	fig. 3
	Safety notes: Be sure to wear Safety Glasses when
	removing the lamp. Do not attempt to remove the lamp
	assembly until the projector has had an ample amount of
	time to cool down.( 1 hour. )
	After removing the lamp assembly, do not look at the
	actual lamp.
	Place the lamp assembly face down. This is necessary
	because the metal halide lamp is pressurized and could
	explode causing injury.
2. Installing	1.	Insert the new assembly by pushing on it until it fits snugly	fig 3

	3.	Re-install the lamp cover.	fig 3
	Note: Be sure the lamp cover is installed correctly or the
	projector will not operate due to the safety switch not
	being activated.
	4.	To reset the lamp timer, press and hold down the Enter,
	Adjust Down, and Adjust Right Keys, then apply power to the
