Is INPUT-6 selected on the input select menu screen?
Select INPUT-6 on the input select menu screen for the right input signal.
Is IC2202(EEPROM) accessed by I2C, with PC connected, to read the
DDC_I2C SCL/SDA data?
Check the DDC line and its peripheral circuits.(IC2202 and its peripherals)
YES
Are there the video signal inputs at pins(AN15)(G), (AM15)(B) and (AK16)(R) of
IC8001(CPU)?
Are there the VSYNC/HSYNC signal inputs at pins(AJ16) and (AH16) of IC8001?
Are the LVDS signal outputs at the LVDS 1st channel and 2nd channel of IC8001?
