- Convert to Component in Input-source
- Input the Component (Which has 720p@60Hz YPbPr
- Input the Component (Which has 720p@60Hz YPbPr
signal : 100% Color Bar (MSPG-925F Model : 217/
Pattern: 65 ) into Component.
Pattern: 65 ) into Component.
- Adjust by commanding AUTO_COLOR_ADJUST (0xF1)
0x00 0x02 instruction
2) Confirmation
- We confirm whether “0xF3 (offset), 0xF4 (gain)” address
of EEPROM “0xBC” is “0xAA” or not.
- If “0xF3”, “0xF4” address of EEPROM “0xBC” isn’t “0xAA”,
we adjust once more
- We can confirm the ADC values from “0x06~0x0B”
addresses in a page “0xBC”
* Manual ADC process using Service Remocon. After
enter Service Mode by pushing “ADC” key, execute
“Auto-RGB” by pushing “
“Auto-RGB” by pushing “
G
” key at “Auto-RGB”.
* After Tool option/Area option change, you have to AC power off
Before PCBA check, you have to change the Tool option, Area
option and have to AC off/on (Plug out and in)
(If missing this process, set can operate abnormally)

2) Input HDCP key with HDCP-key- in-program.
3) HDCP Key value is stored on EEPROM(AT24C64) which is
from “0x80” address of 0xA0 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.
* Before HDCP Download, you have to Set the Configuration
