ADJUSTMENT INSTRUCTION
1. Application Range
This  spec.  sheet  applies  to  PB02A  Chassis  applied  PDP  TV
all models manufactured in TV factory.
2. Specification
(1) Because this is not a hot chassis, it is not necessary to use
an  isolation  transformer.  However,  the  use  of  isolation
transformer will help protect test instrument.
(2) Adjustment  must  be  done  in  the  correct  order.  But  it  is
flexible when its factory local problem occurs.
(3) The adjustment must be performed in the circumstance of
25 
c
C  ± 5  cC  of  temperature  and  65  %  ± 10  %  of  relative
humidity if there is no specific designation.
(4) The input voltage of the receiver must keep 100 V - 240 V,
50 / 60 Hz.
(5) Before adjustment, execute Heat-Run for 5 minutes.
V
After Receive 100% Full white pattern (06CH) then
process Heat-run 
(or “8. Test pattern” condition of Ez-Adjust status)
V
How to make set white pattern 
1) Press Power ON button of Service Remocon
2) Press  ADJ  button  of  Service  remocon.  Select  “10.
Test  pattern”  and,  after  select  “White”  using
navigation  button,  and  then  you  can  see  100%  Full
White pattern. 
* In this status you can maintain Heat-Run useless any
pattern generator
* Notice:  if  you  maintain  one  picture  over  20  minutes
(Especially sharp distinction black with white pattern –
13Ch,  or  Cross  hatch  pattern  –  09Ch)  then  it  can
appear image stick near black level. 
3. Adjustment items
3-1. PCB Assembly adjustment
(1) Adjust 480i Comp1 
(2) Adjust 1080p Comp1/RGB 
- If it is necessary, it can adjustment at Manufacture Line
- You  can  see  set  adjustment  status  at  “9.  ADJUST
CHECK” of the “In-start menu” 
3-2. Set Assembly Adjustment
(1) EDID (The Extended Display Identification Data )
(2) Color Temperature (White Balance) Adjustment
(3) Make sure RS-232C control
(4) Selection Factory output option
4. PCB Assembly Adjustment
4-1. Using RS-232C
- Adjust 3 items at 3-1 PCB assembly adjustments 
“ (3) Adjustment sequence” one after the order.
