1. ADJUSTMENT PROCEDURE START-UP
The 32/42HDT20 PDP TV set, undergoes through
adjustment procedures during its assembly process.
These adjustments must be done to assure the best
performance of the PDP set for the consumer.
Also, after servicing, these same adjustments must be
done. The adjustments are all made through the I2C bus
by changing data in the Adjustment mode menu.
Tab le 1 shows the complete parameter list with a brief
description, signal format, the adjustment range, the
initial data and the average adjustment values for the
parameters that must be adjusted.
1-1 HOW TO GET TO ADJUSTMENT MODE
Chassis adjustment can be done by using the AVC20
front control panel buttons with PDP set turned off. Press
“POWER” and “INPUT” keys at the same time, and hold
for more than 3 seconds. Release the “POWER” button
first and then immediately the “INPUT” button. The PDP

1-2. Changing Data and Selecting Adjustment Code
When the PDP set is in adjustment mode, the cursor , , , 
and MENU keys of the remote control or front panel may be used
as the adjustment keys.
A. Use any Hitachi remote control when making an adjustment.
, keys are used for selecting adjustment code.
, keys are used for changing data values.
MENU key is used to advance through the adjustment mode
menus and pages.
B. To make a selection, use the CURSOR keys on the AVC front
control panel or the Remote Control.
C. After finishing the necessary adjustment press the R/C EXIT
key or EXIT key on the front panel.
Adjustment mode is released and PDP set returns to normal
condition.
2. MEMORY INITIALIZE
2-1. MEMORY INITIALIZE OPERATION
NOTE: The execution of this function returns the
adjustment codes to the initial values, therefore,
adjustment data will be lost.We advise taking a
note of all values or at least the data from
adjustments that must be done (factory and service
adjustments) before following the next procedures.
Procedure 1
There are two procedures for memory initialize, this is the first.
(1) Enter Adjustment mode by the method described in
sub-items 1-1 and 1-2 from item I. “Adjustment
procedure start up.”
(2) Get to the second page of Adjust Mode by pressing
remote control “Menu” key once, or with either the
R/C or front panel , cursor keys several times.
(3) Select MEMORY INIT adjust code.
(4) Activate MEMORY INIT by pressing cursor key for
more than 3 seconds.
(5) Check that the receiving channel goes to CH03. Unit
is set to factory settings and adjustment data
changed to its inital values.
Procedure 2
This is the second procedure for executing memory initialize to
the PDP set
(1) Remove the AVC20 case cover.
(2) With a metal tip, short the PRST connector on the AV
P. W. B .
(3) Check that the set returns to delivery settings.
2-2. Factory and Service Adjustments

initialize operation are shown below:

3.-Sub Contrast adjustment (AVC Center)
This adjustment is only necessary if picture contrast seems to be
deficient, memory initialization was done without making a note
of the settings, or if the IC I001(main micon) or I003 (EEPROM)
were changed.

Adjustment point location
Adjustment preparation
1. Remove the 7 screws from the top cover case.
2. Turn on the TV set for at least 20 minutes before the
adjusment.
3. After the 20 minutes heat-run, turn off the PDP TV set, remove
the AVC20 top cover and turn the set back on by activating the
adjustment mode (Check page 30). Press MENU key once after
activating the Adjustment Mode to reach the sub-contrast codes.
4. Input the RF adjustment signal through antenna A
(Recommended channels, VHF 03 or 04)
5. Connect the oscilloscope probe to the 5th pin if sub-picture
adjustment, or 1st pin if main picture adjustment of PSY or PSY2
free connector terminals in the AV PWB. You can reach this
adjustment points by entering the probe between the FC/MSC
module and the U102 tunner unit.
6. Set SPLIT PIP mode with the remote control and receive the
adjustment signal in both pictures, main and sub.
Adjustment procedure
1. Set the oscilloscope to display one horizontal period.
2. Adjust the amplitude of the signal with SUB CONTRAST(_)
code value, to have 1.38Vdc between black level and white level.

4.- RGB Amplitude Adjustment (AVC Center)
Preparation
(1) Select “Video” - “Picture Mode” - “Sports” - “Reset”.
Set “Reset” of “Video” menu when PC input is
selected.
(2) Confirm the ‘Adjustment Item,’ of the Table 2 to be at
‘Initial Value’.
(3) Input 525p(480p) of RGB amplitude adj. signal into
INPUT1(Component) input.
(4) Input 750p(720p) of RGB amplitude adj. signal into
INPUT1(Component) input.
(5) Input VGA(60Hz) RGB amplitude adj. signal into
RGB1 input.
Note: Perform pre heat-run for more than 30 min. before
adjusting.
Adjustment
(1) Receive 525p(480p) signal, and set the Adjustment
Mode menu items to the following values:
R/G/B BRIGHT = ‘5AH’
BRIGHT CENT = ‘50H’
FLAMAX = ‘27H’
(2) Select ‘RGB(480p)’ of Service Adj. menu. Press right
cursor key () over 2 seconds and have it perform
automatic adjustment. When it’s completed, ‘Auto
Adjusting’ on the screen will disappear.
(3) Receive 750p(720p) signal, and set the Adjustment
Mode menu items to the following values:
R/G/B BRIGHT = ‘5AH’
BRIGHT CENT = ‘50H’
FLAMAX = ‘27H’
(4) Similarly as (2), select ‘RGB(720p)’ of Service Adj.
Menu. Press for 2 sec. to have it perform
automatic adjustment.
(5) Receive PC signal (VGA(60Hz)), and set the
Adjustment Mode Menu items to the following:
R/G/B BRIGHT = ‘5AH’
BRIGHT CENT = ‘50H’
FLAMAX = ‘3FH’
(6) Similarly as (2), select ‘RGB(PC)’ of Service Adj.
Menu. Press for 2 sec. to do automatic
adjustment.
(7) After these adjustments, change the ‘ADJUST
MODE’ Menu items to the “Set Values’ from table 2.
