4-3. MEMORY WRITE CONFIRMATION METHOD
1. After completing all adjustments turn the set off with the Remote Commander and WAIT for the fans to turn off before proceeding to the
next step.
Note: It may take up to two minutes for the fans to stop.
Caution: To avoid over heating the lamp, do not unplug the set until the fans have stopped.
Caution: To avoid over heating the lamp, do not unplug the set until the fans have stopped.
2. After the fans have stopped, unplug the set from the AC outlet, then plug the set back in the AC outlet.
3. To verify the changes repeat steps 2 through 5 from sections 2-1. Setting the Service Adjustment Mode and 2-2. Service Adjustment Mode
Memory.
4. To exit service mode, turn the power off.
Note: To restore the User Controls and Channel Memory settings to the preset factory conditions, put the set into service mode (step
2 from 2-1. Setting the Service Adjustment Mode), then press 8 then
on the Remote Commander. The set will restart and
display the initial setup screen.

4-5. H/V CENTER CONFIRMATION AND ADJUSTMENTS
Please check the picture horizontal/vertical center after the replacement of the Optics Unit Block Assembly or any part of the Top assembly.
1. Check the H/V center with 480i monoscope signal in “Full” mode.
2. If the center is shifted, adjust using the following service items:
NOTE: Please record the steps shifted as
MDHP and
MDVP
.
3. Change the WIDE mode to “Normal” and change the register data as follows:
MDVP
MDHP
MID-X1 9 MDHP (for H center)
10 MDVP (for H center)
4. Display the Twin Picture with the “split” button of the remote commander and change the registers data as follows:
MID-X1 9 MDHP +
MDHP
(Don’t change the MDVP data)
MID-X1 9 MDHP +
MDHP
10 MDVP +
MDVP
5. Press “Favorites” button and change the registers data as follows:
6. OSD horizontal position must be adjusted as follows:
If above sum exceeds 255, set 1 to “16 RP1H” and set the “sum-256” to “17 RP1L”.
Since the registers are different from other cases, be careful to follow complete instructions, and write the data before changing the
display/ wide mode .
