SHARP LC-32D50

ADJUSTMENT PROCEDURE
The adjustment values are set to the optimum conditions at the factory before shipping. If a value should become improper or an adjustment is required due to part replacement, make an adjustment according to the following procedure.
1. After replacement of any PWB unit and/or IC for repair, please note the following.
# When replacing the following units, make sure to prepare the new units loaded with updated software.
MAIN Unit: DUNTKD640FM13
IF Unit: DUNTKD643FM13
2. Upgrading of each microprocessor software
Caution: Never "POWER OFF" the unit when software upgrade is ongoing. Otherwise the system may be damaged beyond recovery.
Software version upgrade
The model employs the following software.
# Main software
# Monitor microprocessor software
The main software and the monitor microprocessor software can be upgraded by using a general-purpose SD memory card.
The followings are the procedures for upgrading, explained separately for each of the main software, the monitor microprocessor software.
Main software version upgrade
Get ready before you start
# SD memory card of 32MB or higher capacity
# PC running on Windows 98/98SE/ME/2000/XP operating system
# SD memory card reader/writer with USB connectivity.
# SD memory card formatting software
Preparations
To upgrade the main software, it is necessary to get ready the SD card for version upgrade before you start.
Follow the steps below and create the SD card for version upgrade.
1. Insert the SD card into the SD card reader/writer. Start the SD card formatting software. Click [Format].
(When you have the drive options, select the drive where the SD card is inserted before you proceed.)
2. When the formatting is over,  Click [OK].
3. Click [Exit] to finish the formatting.
NOTE: When you are done, take out the SD card once to make sure it is finished, and then insert it again.
4. Copy the binary image file D50UAxxx.SDC (named temporarily) for version upgrade to the root directory (folder) of the SD card drive.
NOTE: In the SD card drive, do not store other folders or unrelated files, or more than one binary image files for version upgrade.
Now the SD card for version upgrade is ready.
How to upgrade the software
5. Shut off the AC power (i.e. unplug the AC cord).
6. Insert the SD card for version upgrade (prepared as above) into the service socket located lower side from center at terminals, above S-VIDEO terminal in the rear of the unit, in a way that the cut corner of the SD card comes at the upper side.
NOTE: If the SD card is inserted in a wrong way, the card will go deep inside the unit beyond retrieval. Take due care to insert the SD card correctly.
7. Turn on the AC power (i.e. plug in the AC cord).
8. After the unit startup, the system upgrade screen as shown below appears within 20-40 seconds.
9. Even a single failure in the process will trigger the upgrade failure screen as shown below. The word "NG" changes to red for the item failed.
NOTE: In the event of a failure, repeat the upgrading process. If the process repeatedly fails, it is likely that the hardware is troubled.
10.Upon completion of the whole process, the upgrade success screen as shown below appears. You can check the new software version on this
screen. The version information appears after the upgrade is complete.
11.Shut off the AC power to the unit (unplug the AC cord), and remove the SD card for version upgrade.
12.Now the software version upgrade is complete.
NOTE: When you are done with the software version upgrade, start the set, go to the top page of the adjustment process screen and check the main
software version information.
Monitor microprocessor software version upgrade
NOTE: If "Monitor version" in the process menu is "2.00M", the monitor microprocessor software can not be rewritten (because IC2002 has been
replaced with the mask type).
Get ready before you begin
Get ready the same items as listed in the "Main software version upgrade".
Preparation
Create the SD card for monitor microprocessor software version upgrade in the same manner as explained in the "Main software version upgrade".
Copy the binary image file M150Mxxx.SDC (named temporarily) for monitor microprocessor software version upgrade to the SD card drive.
How to upgrade the software
1. Shut off the AC power to the unit (i.e. unplug the AC cord).
2. Insert the SD card for version upgrade (prepared as above) into the service socket located lower side from center at terminals, above S-VIDEO terminal in the rear of the unit, in a way that the cut corner of the SD card comes at the upper side.
NOTE: If the SD card is inserted in a wrong way, the card will go deep inside the unit beyond retrieval. Take due care to insert the SD card correctly.
3. Turn on the AC power (i.e. plug in the AC cord).
CAUTION: The moment this operation is done, the upgrading of the monitor microprocessor software starts. While the upgrade is ongoing, never power off the unit. Otherwise the upgrade will fail and the system may have a serious damage beyond recovery (inability to start).
4. After the unit startup, the system upgrade screen as shown below appears within 10-30 seconds.
5. A failure in the process will trigger the upgrade failure screen. The word "NG" changes to red for the item failed.
NOTE: In the event of a failure, repeat the upgrading process. If the process repeatedly fails, it is likely that the hardware is troubled.
6. Upon completion of the whole process,the upgrade success screen as shown below appears.You can check the new software version on this screen. The version information appears after the upgrade is complete.
7. Shut off the AC power to the unit (unplug the AC cord), and remove the SD card for version upgrade.
8. Now the software version upgrade is complete.
NOTE: When you are done with the software version upgrade, start the set, go to the top page of the adjustment process screen and check the monitor microprocessor software version information.
Adjustment of white balance
[Adjustment method]
1) Send the “monitor adjustment process” code with the R/C.
2) Set the point 6 to the specified gradation. Set the strongest color as the fixed color and adjust RGB to the standard value by minus adjustment.
3) Set the point 5 to the specified gradation. Set the correction value of G [(Initial value of point 5) x (G value of point 6) / (Initial value of point 6)] and adjust RB to the standard value.
4) Set the point 4 to the specified gradation. Set the correction value of G [(Initial value of point 4) x (G value of point 6) / (Initial value of point 6)] and adjust RB to the standard value.
5) Set the point 3 to the specified gradation. Set the correction value of G [(Initial value of point 3) x (G value of point 6) / (Initial value of point 6)] and adjust RB to the standard value.
6) Set the point 2 to the specified gradation. Set the correction value of G [(Initial value of point 2) x (G value of point 6) / (Initial value of point 6)] and adjust RB to the standard value.
7) Set the point 1 to the specified gradation. Set the correction value of G [(Initial value of point 1) x (G value of point 6) / (Initial value of point 6)] and adjust RB to the standard value.
8) Write the adjustment values with the MSET0003 command and turn off AC power.
Initialization (Factory reset )
Place the cursor on the [INDUSTRY INIT] row, set "ON" with [+] or [-] of the [VOL] key, and press the [ENT] key.
Version confirmation screen appears.
[SUCCESS] on a green line indicates that the setting is successfully completed. (In case of an error, [ERROR] and an error code appear on a red line.)
Turn off the AC power.
