4 – 6
No video (6)
PC: No external input video [INPUT-6]
Is INPUT-6 selected on the input select menu screen?
YES
NO
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 cir-
cuits. (IC2202 and its peripherals).
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?
NO
Check the line between SC2201 and IC8001 (Q2211, IC2201,
etc.).
YES
Are digital video (LVDS) signals sent from pins B5~7, C5~7,
D5~7, and E5~7 of IC8001?
NO Check the line between IC8001 and IC5103.
YES
Check IC8001 and peripheral circuits.
Are digital video (RSDS) signals sent from IC5103 to SC5201 and
SC5202?
NO Check the line between IC5103 and SC5201 and SC5202.
YES
Check IC5103 and peripheral circuits.
Check between (SC5201, SC5202) and LCD Panel.
