This spec. sheet is applied to all of the PD91A chassis.

1. The module keeping condition: The normal temperature

condition(more than 15°C)
--> Immediately the line supply.

2. The module keeping condition: 0°C

-->  The module must be kept for more than 2 hours at the

normal temperature.

3. The module keeping condition: -20°C

-->  The module must be kept for more than 3 hours at the

normal temperature.

4. The case of Gu-mi factory at the winter season.

-->  The module must be kept for more than 5 minutes at

the heating zone(40°C~45°C).

(1) The adjustment is according to the order which is

designated and which must be followed, according to the
plan which can be changed only on agreeing.

(2) If there is no specific designation, the adjustment must be

performed in the circumstance of 25±5°C of temperature
and 65±10% of relative humidity.

(3) The input voltage of the set must keep 100~240V,

50/60Hz.

(4) Input signal Unit: Product Specification Standard.
(5) The set must be operated for about 5 minutes prior to the

adjustment.

- Set heat run should be activated without a signal generator. 
- Single color patterns (RED / BLUE / GREEN) of HEAT RUN

MODE are used to check a plasma panel. 

- Caution: If you turn on a still screen more than 20 minutes

(Especially digital pattern, cross hatch pattern), an after
image may be made in the black level part of the screen.

[Caution] 
- Use ‘power on’ button of a service R/C to power on TV set.
- Do not connect any external input cable if there is no any

specifics.

Caution: S/W version of USB file (xxx.epk) must be bigger than

one which is downloaded previously.

(1) Insert the USB stick to the USB socket 
(2) A downloaded file in USB stick will be detected

automatically.

(3) If S/W version of USB file (xxx.epk) is bigger than one

which is downloaded previously, the message, “Copying
files from memory”, will appear. 

(4) If an update procedure was completed, TV set will be

turned off and on automatically.

(5) If TV set is turned on, check an updated version.

* If a downloaded version is more bigger than one of which

TV set had, TV set can lost channel data. In this case,
you have to scan channels again. 

(1) Push “IN-START” button on a service R/C.
(2) Select “Tool Option 1” and Push “OK” button.
(3) Put the number of a below table in order of a suffix of the

“Tool Option(X)”. 
(Each model has a different number.)

(1) Input the component (480i/Horizontal Color Bar) signal to a

TV set.
1) Input Signal Timing : Component 480i 

(Other external connection is unnecessary except the
component before executing ADC calibration.)

2) Input Signal Pattern

@ MODEL: 209 in Pattern Generator(480i Mode)
@ PATTERN : 65 in Pattern Generator(MSPG-925

SERISE) 

(2) Push “ADJ” button on a service R/C.
(3) Enter internal ADC mode by selecting ‘5. ADC Calibration’.
(4) If you select ‘Start’ on a dialog box of the screen, ADC

calibration will be begun.

Caution: Don’t connect any external input cable except the

component input(480i/Horizontal_Color_Bar) to adjust
ADC calibration

You must adjust DTV 29 Channel and insert PCMCIA CARD
to socket.
- If PCMCIA CARD works normally, video signals will appear

on screen.
But it works abnormally, “No CA module” will appear on
screen.

Caution: Set up “RF mode” before launching products.

Caution: Both Vs and Va voltage adjustment are necessary.

50PS7000-ZA, 60PS7000-ZA, 50PS8000-ZA, 60PS8000-ZA

(1) Connect positive(+) terminal of DMM to Vs/Va pin, connect

negative(-) terminal to GND.

(2) Turning ‘Vs/Va Adjust’ and adjust Vs/Va voltages to a

value which is written on a right/top label of a module.
(deviation ; ±0.5V)

[Caution]

- Each Power Supply Unit PCB assembly must be checked by

check JIG set. (Because power PCB Ass’y damages to PDP
Module, especially be careful)

- Set up “RF mode(noise)” before a voltage adjustment.
- Test equipment: DMM 1EA

Caution: Press the POWER ON KEY on R/C before W/B
adjustment.

Test Equipment

Color Analyzer (CS-1000, CA-100+(CH.10), CA-210(CH.10))

O

Please adjust CA-100+ / CA-210 by CS-1000 before

measuring
You should use Channel 10 which is Matrix compensated
(White, Red, Green, Blue revised) by CS-1000 and adjust

in accordance with White balance adjustment coordinate.
