These instructions are applied to all of the PDP TV, PA73A.

(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 equipment.

(2) Adjustments must be done in the correct order.
(3) The adjustments must be performed in the circumstance of

25±5°C of temperature and 65±10% of relative humidity if
there is no specific designation.

(4) The input voltage of the receiver be must kept 110V, 60Hz

when adjusting.

(5) The receiver must be operational for about 15 minutes

prior to the adjustments.

Component 480i/1080p RGB 1080p adjustment to set the
black level and the Gain to optimum.

(1) Service R/C
(2) 801GF(802B, 802F, 802R) or MSPG925FA Pattern

Generator (480i/1080i  The Horizontal 100% Color Bar
Pattern adjust to within  0.7±0.1Vp-p)

[

Because the above pattern can differ by the model and

pattern for each device, you must check the pattern first.

(1) Receive the 480i Mode, 100% Horizontal Color Bar

Pattern(HozTV31Bar) to Component 1 port.
(MSPG-925FA:  ==>  Model : 209, Pattern : 65) 

(2) Press the ADJ on the adjustment R/C to enter ‘Ez –

Adjust’. Select ‘1. Adjsut 480i Comp1’ using the 

E 

and

press the 

G

to make the automatic adjustment.

(3) When the adjustment is over, 'ADC Component1 Success’

is displayed. If the adjustment has errors, 'ADC
Component1 408i Fail’ is displayed.
[Fail Message]

- If the component is not connected: Component1 Not

Connected

- If the input format is not 480i: Not Valid Format 
- If the input signal is not generated: Check Signal Status

(4) Readjust after confirming the Pattern or adjustment

condition

(5) After adjustment is complete, exit the adjustment mode by

pressing the ADJ.

(1) Receive the 1080p Mode, 100% Horizontal Color Bar

Pattern(HozTV31Bar) to Component1 and RGB port.
(MSPG-925FA: ==> Model : 225 , Pattern : 65) 

(2)  After connecting, wait for the image displayed on the

screen

(3) Press the ADJ on the adjustment R/C to enter ‘Ez –

Adjust’. Select ‘2. Adjsut 1080p Comp1/RGB’ using the 

E

and press the 

G

to make the automatic adjustment.

(4) When the adjustment is over, 'ADC Component1 Success’

is displayed. If the adjustment has errors, 'ADC
Component1 1080p Fail’ is displayed.

(5) When the Component1 adjustment is normally completed,

the RGB adjustment automatically starts. 

(6) When the adjustment is over, 'ADC RGB 1080p Success’

is displayed. 

(7) When the adjustment has errors, 'ADC RGB 1080p Fail’ is

displayed.
[Fail Message]

- If the component is not connected: Component1 Not

Connected

- If the input format is not 480i: Not Valid Format 
- If the input signal is not generated: Check Signal Status

(8) Readjust after confirming the Pattern or adjustment

condition

(9) After adjustment is complete, exit the adjustment mode by

pressing the ADJ.

Adjustment of RF and video signal

(1) Connect the Video Signal Generator (Master) to AV1 port

and input the signal.
Test Equipment: MSPG925FA Pattern Generator
(Model: 201(NTSC-M), Pattern: 33(100% color Bar))
At this time, press the Rev button certainly.

[

Because the above pattern can differ by the model, pattern

and rev button for each device, you must check the pattern
first.

(2) Apply the RF signal to the antenna. (Make sure that the

signal is received)

(3) Enter the ‘Ez - Adjust’ by pressing the ADJ on the Service

R/C.
After select the ‘3.Adjust RF and Video’, start the
adjustment by pressing the Right Key(

G

).

When it enters the adjustment mode, the screen is
automatically split as TV 2CH SPLIT as shown at the
below figure.

(4) When the adjustment is over, 'RF Configuration Success’ is

displayed. If the adjustment has errors, 'RF Configuration
Error’ is displayed.

(5) When adjusting the RF signal is completed, it is

automatically switched to the Video mode as shown at the
below figure, and the automatic adjustment for the Video
mode starts.

(6) When the adjustment is over, 'AV Configuration Success’ is

displayed. If the adjustment has errors, 'AV Configuration
Error’ is displayed.

Preliminary action is applied to the test for afterimage

discharge detection, and 100% FULL WHITE PATTERN
must be operated automatically.

(1) Pressing Power On key on the adjustment R/C
(2) Full Test Pattern(2 min 30sec) --> Full Black

Pattern(30sec) --> Full White Pattern
(Full White Pattern when the main power is turned on
again after being turned off) 

(3) Pattern Mode is deselected by pressing CH +/-, Exit Key.

[

Set is activated HEAT-RUN without signal generator in this

mode.

1) Connect + terminal of D.M.M to Va pin of P805 and

connect – terminal  to GND pin of P805.

2) Adjust RV501 voltage to match that of the label on the

Top/Right of the panel. (Deviation : ±0.5V)

1) Connect + terminal of D.M.M to Vs pin of P805 and

connect – terminal  to GND pin of P805.

2) Adjust RV401 voltage to match that of the label on the

Top/Right of the panel. (Deviation : ±0.5V)

6. EDID(The Extended Display 

It is the feature to implement the “Plug and Play” which
automatically reconfigures the user’sl environment to directly
use by exchanging information without any command directly
to the PC or the monitor by the user, which is established by
the VESA

(1) PC(S/W: EDID TESTER Ver.2.5)
(2) EDID Download JIG (PC serial to D-sub connection cable)
(3) Connection Cable

Test Pattern 2min 30sec

Test Pattern 30sec

If you turn on a still screen more than 20 minutes (Especially
Digital pattern(13 CH), Cross Hatch Pattern), an afterimage
may occur in the black level part of the screen.

Each PCB Assy must be checked by Check JIG Set before
assembly. (Especially, be careful Power PCB Assy which can
cause Damage to the PDP Module.)
