4. USB DOWNLOAD
4-1. Preliminary steps
(1) Put the USB Stick to the USB socket
(2) Automatically detecting update file in USB Stick
(3) Select “Start” Button and press “ok” button
(4) Updating is staring.
(4) Updating is staring.
(5) After finish firmware update, The TV set reset detect the
update file automatically.
5. Auto Color Balance(ADC)-RGB
* Required Equipments
- Remote controller for adjustment
- MSPG-925F Pattern Generator
- MSPG-925F Pattern Generator
5-1. Method of Auto RGB Color Balance
(1) Convert to RGB PC in Input-source
(2) Input the PC 1024x768 @ 60Hz 1/2 Black & White Pattern
(2) Input the PC 1024x768 @ 60Hz 1/2 Black & White Pattern
into RGB.(MSPG-925F model:60, pattern:54)
(3) Adjust by commanding AUTO_COLOR_ADJUST(0xF1)
0x00 0x02 instruction.
5-2. Confirmation
(1) We confirm whether “0xF1 (offset), 0xF2 (gain)” address of
EEPROM “0xBC” is “0xAA” or not.
(2) If “0xF1”, “0xF2” address of EEPROM “0xBC” isn’t “0xAA”,
we adjust once more
(3) We can confirm the ADC values from “0x00~0x05”
addresses in a page “0xBC”
* Manual ADC process using Service Remocon. After enter
Service Mode by pushing “ADJ” key, execute “Auto-RGB” by
pushing “
pushing “
G
” key at “Auto-RGB”.
6. Auto Color Balance(ADC)-Component
6-1. Method of Auto Component Color Balance
(Component Gain/ Offset Adjustment)
(1) Convert to Component in Input-source
(2) Input the Component (Which has 720p@60Hz YPbPr
(2) Input the Component (Which has 720p@60Hz YPbPr
signal : 100% Color Bar into Component. (MSPG-925F
Model: 217/ Pattern: 65 )
Model: 217/ Pattern: 65 )
(3) Adjust by commanding AUTO_COLOR_ADJUST (0xF1)
0x00 0x02 instruction
6-2. Confirmation
(1) We confirm whether “0xF3 (offset), 0xF4 (gain)” address of
EEPROM “0xBC” is “0xAA” or not.
(2) If “0xF3”, “0xF4” address of EEPROM “0xBC” isn’t “0xAA”,
we adjust once more.
(3) We can confirm the ADC values from “0x06~0x0B”
adresses in a page “0xBC”.
* Manual ADC process using Service Remocon. After enter
Service Mode by pushing “ADJ” key, execute “Auto-RGB” by
pushing “
pushing “
G
” key at “Auto-RGB”
