This spec. sheet is applied to all of the PP81A Chassis.

(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.
(3) The adjustment must be performed in the circumstance of

25±5

c

C of temperature and 65±10% of relative humidity if

there is no specific designation.

(4) The input voltage of the receiver must keep 100~240V,

50/60Hz.

(5) Before adjustment, execute Heat-Run for 30 minutes at RF

no signal.

1) Convert to PC in Input-source
2) Signal equipment displays

Output Voltage  :  700  mVp-p
Impress Resolution XGA (1024 x 768 @ 60Hz)
Model : 60    in Pattern Generator
Pattern : 54   in Pattern Generator (MSPG-925 SERISE) 
[1/2 Black & White Pattern (Refer below picture)].

3) Adjust by commanding AUTO_COLOR_ADJUST(0xF1)

0x00 0x02 instruction.

1) We confirm whether “0xB6(RGB)” address of EEPROM

“0xA2” is “0xAA” or not. 

2) If “0xB6(RGB)” address of EEPROM “0xB2” isn’t “0xAA”,

we adjust once more

3) We can confirm the ADC values from “0xB0~0xB5(RGB)”

addresses in a page “0xA2”

[

Manual ADC process using Service Remocon. After enter

Service Mode by pushing “ADJ” key, execute “ADC Adjust” by
pushing “

G

” key at “Adjust-RGB”. 

1) Convert to Component in Input-source
2) Signal equipment displays

Impress Resolution  720P
MODEL : 216   in Pattern Generator(720P Mode)
PATTERN : 33  in Pattern Generator( MSPG-925 SERISE) 

3) Adjust by commanding AUTO_COLOR_ADJUST(0xF1)

0x00 0x02 instruction

1) We confirm whether “0xC8(720P)” address of EEPROM

“0xA2” is “0xAA” or not. 

2) If “0xC8(720P)” address of EEPROM “0xA2” isn’t “0xAA”,

we adjust once more

3) We can confirm the ADC values from “0xB9~0xBE(480i)/

0xC2~(1080i)” addresses in a page “0xA2”

- 5 -

Tool Option1 
Tool Option2
Area Option

* Profile: Must be changed the option value because being

different with some setting value depend on module, inch
and market 

* Equipment : Adjustment Remote Controller

(1) Push the IN-START key in the Adjust R/C.
(2) Input the Option Number that was specified in the BOM,

into the Shipping area.

(3) Select “Tool Option1/ Tool Option2/ Area Option” by using

D

/

E

(CH+/-) key, and press the number key(0~9)

consecutively
ex) If the value of Tool Option1 is 7, input the data using

number key “7” (Fig. 2)

Caution: Don’t Push “IN-STOP” key after PCB assembly

adjustment.

(4) Adjustment method    

Before PCBA check, have to change the Tool option and
Area option

About PDP

After done all adjustments, Press IN-START button and
compare Tool option and Area option value with its BOM, if it
is correctly same then Change “RF mode” and then unplug
the AC cable.
If it is not same, then correct it same with BOM and unplug AC
cable. 
For correct it to the model°Øs module from factory JIG model.

Don’t push The IN-STOP KEY after completing the function

inspection.
