VIDEO SYSTEM CONTROLLER (IC3610 126 pin) outputs a reset
signal to VIDEO PROCESSOR 1 (IC3601 AD9pin). Then, VIDEO
PROCESSOR 1 starts to read the operation firmware from FLASH
MEMORY (IC3615). And, VIDEO PROCESSOR 1 reads backup data of
calibration in EEPROM (IC3621).
PROCESSOR 1 starts to read the operation firmware from FLASH
MEMORY (IC3615). And, VIDEO PROCESSOR 1 reads backup data of
calibration in EEPROM (IC3621).
This VIDEO PROCESSOR 1 is called “FAROUDJA” or “FAROUDJA
Main” in Technical information.

(Troubleshooting) Video related circuit operation
VIDEO CONTROLLER (IC3610) communicates with VIDEO
PROCESSOR 1 (IC3601), VIDEO PROCESSOR 2 (IC3606) and OSD
CONTROLLER (IC3604). If one of IC communication is not established
well, the firmware version of VIDEO CONTROLLER is shown as
“Video Ucom Ver 0.00” in SPECIAL MENU MODE of test mode on
page 25.
