CONTROLLING THE TOTAL OPERATING HOURS OF THE LAMP
The following control is carried out when the lamp has been used for 1900 hours and 2000
hours.
1. After 1900-hour use
When the power is turned on, "LAMP" appears in the on-screen display for about 1 minute (flashing in yellow)
and the lamp LED indicator lights up in red. When the 1,900-hour point comes up during use of the unit, the
"LAMP" display starts flashing in yellow on the screen for 1 minute at the very 1,900-hour point. Now the lamp
LED indicator changes from green to red.
2. After 2000-hour use
When the power is turned on, "LAMP" appears in the on-screen display for about 5 minutes (flashing in red) and
the lamp LED indicator lights up in red. Five minutes thereafter, the power turns itself of f and the unit is interrupted.
When the 2000-hour point comes up during use of the unit, the "LAMP" display starts flashing in red on the
screen for 5 minutes at the very 2000-hour point. Five minutes later, the power turns itself off and the unit is
interrupted. (The lamp LED indicator stays red since the 1900-hour point.)
If you try to turn on the power three times after the 2000-hour point, the unit remains off.
3. When the 2000-hour point comes up, take the following steps.
Replace the lamp with new one. While holding down both the "VOL."" and "ADJ."" keys on the unit, turn on the
main power switch (located on the side of the unit). The lamp operating hourmeter is now reset to zero. T urn on
the unit and make sure the time display shows "0000H".
4. Displaying the total operating hours of the lamp (used to check the total time)
Change the STATUS3 data settings: PICTURE at 0, BRIGHT at MAX, COLOR at MIN, TINT at MIN, and
SHARPNESS at MAX. Hold down the SOUND DOWN and ENTER keys for longer than 3 seconds. By doing
this, the total operating hours will be displayed on the screen.

CONVERGENCE AND FOCUS ADJUSTMENT
» Start the convergence and focus adjustments with the top cabinet and the signal shield
removed but the power on. Use the remote control gun to adjust the image. Take the
following procedures.
1. Focusing the projection lens
(A) Replacing all the 3 LCD panels
1. Before replacing all the 3 LCD panels, project an image on the screen and bring it into focus.
2. Replace the panels with new ones. But until the focus has been completely readjusted, be careful not to
change the distance between the set and the screen, nor to move the projection lens focus and zoom
rings.
If the focus is readjusted with a different positional relation, the relation between the projection distance
and the screen size is affected. In other words, a short-distance image (40 WIDE, for example) may get
(
out of the focus range, or a long-distance image (300 WIDE, for example) may come out of focus.
(B) Replacing 1 or 2 of the 3 LCD panels
1. In adjusting the focus after replacement of one or two LCD panels, project an image on the screen and turn
the projection lens focus ring to get the non-replaced LCD panel into focus.
2. But until the focus has been completely adjusted for the new LCD panels, be careful not to change the
distance between the set and the screen, nor to move the projection lens focus and zoom rings.
(If the distance has been changed or the projection lens readjusted, repeat the above steps 1 and 2.)
)
2. Adjusting the G-LCD panel
(A) Focus adjustment. (Make this adjustment on the white-only screen.)
1. Right-and-left focus adjustment (θY direction) .
Loosen the lock screws "b" and "c" and insert the eccentric screwdriver into the notch and hole "b". Turn
the screwdriver until the right and left halves on the screen get into focus.
First get the right and left halves in balance. Then improve the accuracy while making the adjustment 2
(
below.
2. Top-center-bottom focus adjustment (θX and Z directions).
Loosen the lock screws "a" and "c" and insert the eccentric screwdriver into the notch and hole "a" or "c".
Turn the screwdriver until the top, center and bottom on the screen get into focus. In adjusting this top-tobottom focus, temporarily tighten the lock screw "b" to fix the θY direction adjustment.
3. Repeat the above steps 1 and 2 to finely adjust the focus. Finally tighten up all the lock screws.
Note :
1 Carefully proceed with the focus adjustment because the adjusting directions are correlated.
2 In adjusting the convergence and focus, do not move the projection lens zoom and focus rings until the end
of all the adjustments.
(B) Convergence adjustment
» The G-LCD panel has no convergence adjustment mechanism. Use this panel as convergence adjustment
reference.
3. B-LCD panel adjustment (the same for the R-LCD panel)
(A) Focus adjustment
» T ake the same procedure as for the G-LCD panel focus adjustment. Note that the adjustment range is small
in the Z direction. If the convergence is quite different between the B-LCD and G-LCD panels, roughly adjust
the convergence first and then the focus.
(B) Convergence adjustment
» Use a crosshatch pattern signal for this adjustment.
Make the adjustment just for the G-colour and the relevant colour.
(1) Loosen the convergence lock screw "d".
(2) With the G-LCD panel’s screen center as reference, adjust the B-LCD panel in the X, Y and θZ directions.
(3) Finally tighten up the convergence lock screw "d".
)
17
Page 18
XV-Z1E/A
Note :
1 The eccentric cam is used for convergence adjustment. This means that the cam’s turning and the linear
movement are not always uniform.
2 This model is not equipped with the LCD image adjustment mechanism. This is because the dichroic prism
is used for image formation. When the LCD panels all get into the best focus, the images are almost
completely converged.
