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.
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: DKEYMF452FM01
# When replacing the LCD control PWB, perform the VCOM adjustment.
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 (please use a software version after HLNRBxxx.USB (32” HLNRCxxx.USB).)
# Monitor microprocessor software (please use a software version after HLNRA0x.USB and HLNIMxxx.BIN.)
The main software, monitor microprocessor software can be upgraded by using a general-purpose USB Memory.
The followings are the procedures for upgrading, explained separately for the main software, monitor microprocessor software.
Main software version upgrade
Get ready before you start
# USB Memory of 128MB or higher capacity.
# PC running on Windows 98/98SE/ME/2000/XP operating system.
# USB Memory reader/writer or PC with a USB port.
# The file system of a USB memory is FAT. (FAT32 supports)
# Use the USB memory without other functions. (lock and memory reader...etc)
Preparations
To upgrade the main software, it is necessary to get ready the USB Memory for version upgrade before you start.
Follow the steps below and create the USB Memory for version upgrade.
1. Copy the file HLNRBxxx.USB (32” HLNRCxxx.USB). for version upgrade to the root directory (folder) of the USB Memory.
NOTE: In the USB Memory drive, do not store other folders or unrelated files, or more than one file for version upgrade.
Now the USB Memory for version upgrade is ready
How to upgrade the software
1. Plug AC cord and turn on the TV.
2. After picture displayed, touch the power key for 5seconds.
NOTE: Picture will disappear when you touch the power key, but keep touching it.
3. When the center icon LED blinks, release your finger from the power key.
4. Next, touch the “POWER” and “CH ( UP )” keys at the same time.
5. When the center icon LED turns on, release your finger form the keys.
6. After the unit startup, the system upgrade screen as shown below within 20-40 seconds.
7. Even a single failure in the process will trigger the upgrade failure screen.
NOTE: In the event of a failure, repeat the upgrade process. If the process repeatedly fails, it is likely that the hardware need fixing.
8. 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
9. Unplug the AC cord and remove the USB Memory for version upgrade.
10.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
Create the USB memory for monitor microprocessor software version upgrade in the same manner as explained in the “Main software version upgrade”.
Copy the file HLNRVA0x.USB and HLNIMxxx.BIN (named temporarily) for monitor microprocessor software version upgrade to the USB memory.
How to upgrade the software
1. Plug AC cord and turn on the TV.
2. After picture displayed, touch the power key for 5seconds.
NOTE: Picture will disappear when you touch the power key, but keep touching it.
3. When the center icon LED blinks, release your finger from the power key.
4. Next, touch the “POWER” and “CH ( UP )” keys at the same time.
5. When the center icon LED turns on, release your finger form the keys.
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 be serious damaged beyond recovery (inability to start).
# After the monitor microprocessor software is upgraded, also perform the 'Industry Init'.
6. After the unit startup, the upgrade starts. The power led will blink continuously. Also, an upgrade screen will be shown during a minor upgrade.
7. If the upgrade fails, power led will stop blinking. Also, the upgrade failure screen will be shown
NOTE: In the event of a transient failure, upgrade will be automatically retried up to three times. If the process repeatedly fails, hardware may be the cause.
8. Up on completion of the whole process, power and OPC LED will blink alternately. Also, the upgrade success screen will be shown.
9. Unplug the AC cord and remove the USB Memory for version upgrade.
10.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 and panel size information.
Entering and exiting the adjustment process mode
1) Before entering the adjustment process mode, the AV position RESET in the video adjustment menu.
2) At the state TV is turned on, touch the power key for 5seconds.
NOTE: Picture will disappear when you touch the power key, but keep touching the power key.
3) When the center icon LED blinks, release your finger from the power key.
4) Next, touch the power key with “VOL (-)” and “INPUT” keys at the same time.
TV will turn on and the letter “<K>” appears on the screen.

5) Next, touch the “VOL (DOWN)” and “CH ( DOWN )” keys at the same time.
6) When the center icon LED turns on, release your finger form the keys.
(The “VOL (DOWN)” and “CH (DOWN )” keys should be pressed and held until the display appears.)
Multiple lines of blue characters appearing on the display indicate that the unit is now in the adjustment process mode.
When you fail to enter the adjustment process mode (the display is the same as normal startup), retry the procedure.
7) To exit the adjustment process mode after the adjustment is done, unplug the AC cord from the outlet to make a forced shutdown. (When the power was turned off with the remote controller, once unplug the AC cord and plug it again. In this case, wait 10 seconds or so before plugging.)
CAUTION: Use due care in handling the information described here lest your users should know how to enter the adjustment process mode. If the
settings are tampered in this mode, unrecoverable system damage may result.
White balance adjustment
Adjustment procedure
1) Send the “adjustment process” code using the remote control.
2) Set the point 6 to the specified gradation, specify the strongest color as the fixed color, and adjust the RGB so that it becomes the standard value through negative adjustment. Then compare the R and G values; based on the result, calculate the Ye value in the following conditions.
R > G: Ye = G x 1.05
R G: Ye = R x 1.05
If the Ye value exceeds the initial value (input gradation x 4), it is rounded to that value or less.
3) Set the point 5 to the specified gradation, set the G correction value (692 x G value of point 6/916) (fractions rounded off) and the Ye correction value (692 x Ye value of point 6/916) (fractions rounded off), and adjust the RB so that it becomes the standard value.
4) Set the point 4 to the specified gradation, set the G correction value (532 x G value of point 6/916) (fractions rounded off) and the Ye correction value (532 x Ye value of point 6/916) (fractions rounded off), and adjust the RB so that it becomes the standard value.
5) Set the point 3 to the specified gradation, set the G correction value (464 x G value of point 6/916) (fractions rounded off) and the Ye correction value (464 x Ye value of point 6/916) (fractions rounded off), and adjust the RB so that it becomes the standard value.
6) Set the point 2 to the specified gradation, set the G correction value (296 x G value of point 6/916) (fractions rounded off) and the Ye correction value (296 x Ye value of point 6/916) (fractions rounded off), and adjust the RB pattern so that it becomes the standard value.
7) Set the point 1 to the specified gradation, set the G correction value (180 x G value of point 6/916) (fractions rounded off) and the Ye correction value (180 x Ye value of point 6/916) (fractions rounded off), and adjust the RB so that it becomes the standard value.
8) Write the adjustment value by the MSET0003 command and turn off the AC power.
RGB initial value of point 6: Set gradation 916
RGB initial value of points 1 to 5: G correction value of each point
(At each point, make adjustment so that the remainder of the RGB adjustment value/ 4 is equal.)
Factory setting
After completing the factory setting, pull out the AC cord to complete the setting.
Point the cursor to [INDUSTRY INIT (+Cause)], set to “ON” using [+]/[-] of the [VOL] key,
and press the [ENT] key.
The version confirmation screen appears on the green screen. It is completed when [SUCCESS] is displayed at the top.
(If error occurs, [ERROR] is displayed on the red screen.)
Turn off the AC power.
