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.
