(2) Confirmation
1) We confirm whether “0xB3 (480i)/0xBC (1080i)” address of
EEPROM “0xA2” is “0xAA” or not.
2) If “0xB3 (480i)/0xBC(1080i)” address of EEPROM “0xA2”
isn’t “0xAA”, we adjust once more
3) We can confirm the ADC values from “0xAD~0XB2
(480i)/0XB6~BB (1080i)” 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 “ADC CALIBRATION :COMPONENT”.
Caution: Each PCB assembly must be checked by check JIG
set.
(Because power PCB Assembly damages to PDP
Module, especially be careful)
