(2) Confirmation

1) We confirm whether “0xBF(480i)/0xC8(1080i)” address

of EEPROM “0xA2” is “0xAA” or not.

2) If “0xBF(480i)/0xC8(1080i)” 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”.

* Manual ADC Confirmation using Service Remocon. After

enter Service Mode by pushing “INSTART” key.

2) Connect HDMI Signal Cable to HDMI Jack.
3) Write EDID DATA to EEPROM (24C02) by using DDC2B

protocol.

4) Check whether written EDID data is correct or not. (Refer to

Product spec).

5) Remark

A week manufacture in address 0x10 can be changed. And
thus Checksum (Address: 0x7F) can be also changed.

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) Write data by 64bytes.
5) AC off/ on and on HDCP button of MSPG925 and confirm

whether picture is displayed or not of using MSPG925

6) HDCP Key value is different among the sets. 

1) After all function test., press IN-STOP Key by SVC Remote

controller. And Make Ship Condition. 

2) When pressing IN-STOP key by SVC remocon, Red LED

are blinked alternatively. And then turn off automatically.
(Must not AC power OFF during blinking)

1) Test Voltage

- GND: 1.5KV/min at 100mA
- SIGNAL: 3KV/min at 100mA

2) Test Point

- GND Test = between power cord GND and Signal cable

metal GND

AC input Live.

3) leakage current: 0.5mArms (but, 32LG3DCH as hospital TV

limited by 0.1mArms.)
