This spec sheet is applied to all of the PP78D 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 to protect test instruments.

(2) Adjustment must be done in the correct sequence.
(3) The adjustment must be performed at 25±5°C temperature

and 65±10% relative humidity if there is no specified
designation.

(4) The input voltage of the receiver must be kept between

100~220V, 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 (800 x 600 @ 60Hz)
Model : 46    in Pattern Generator
Pattern : 29   in Pattern Generator (MSPG-925 SERISE) 
[gray pattern that left & right is black and center is white
signal (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 : 08  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”

(1) Use the proper signal cable for EDID Download

-  Analog EDID : Pin3 exists
- Digital EDID : Pin3 exists

(2) Never connect HDMI & DVI-D & DVI-A Cable at the same

time.

(3) Use the proper cables below for EDID Writing

(1) 32PC5DV ANALOG(128 Bytes )

(4) Push the “Write Data & Verify” button. And confirm “Yes”.

(5) If the writing is finished, you will see the “ OK” message.

(High-Bandwidth Digital Contents Protection)

(1) Connect D-sub Signal Cable to D-Sub Jack
(2) Input HDCP key with HDCP-key- in-program
(3) HDCP Key value is stored on EEPROM(AT24C512) which

is 80~A1 addresses of  0xA0~0xA2 page

(4) AC off/ on and on HDCP button of MSPG925 and confirm

whether picture is displayed or not of using MSPG925

(5) HDCP Key value is different among the sets

(1) Purpose: Adjust the color temperature to reduce the

deviation of the module color temperature. 

(2) Principle: To adjust the white balance without the

saturation, Fix the one of R/G/B gain to 80 and decrease
the others.

Two modes of Cool and Warm
(Medium data is automatically calibrated by the cool data)

(1) Remote controller for adjustment
(2) Color Analyzer : CA100, CA-100+, CA-210 or same

product
- PLASMA TV(ch : 10)

(3) Auto W/B adjustment instrument(only for Auto adjustment) 

(For Automatic Adjustment) 

(1) Enter the adjustment mode of the white balance

1) Enter the white balance adjustment mode at the same

time heat-run mode when pushing the power on by
power only key

2) Maintain the white balance adjustment mode with same

condition of Heat-run -> Maintain after AC off/on in
status of Heat-run pattern display

(2) Release the white balance adjustment mode

1) Release the adjust mode after AC off/on or std-by off/on

in status of finishing the Hear-run mode

2) Release the Adjust mode when receiving the aging off

command(F3 00 00) from adjustment equipment

3) Need to transmit the aging off command to TV set after

finishing the adjustment
