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

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.)
