(SC5301) normal?
NO
Check the line between SC5301 and pin(50) of IC5301
(TMDS-SW).
YES
NO
Check the setting of an external input device that con-
nects with HDMI-1/2/3.

TMDS3_D0P/N), (60, 59/TMDS3_D1P/N), (63, 62/ TMDS3_D2P/
N) of IC5301(TMDS-SW) from HDMI-3 (SC5301)?
NO
Check the line between HDMI-3 (SC5301) and IC5301.
YES
Are TMDS_Rx and the I2C_SINK signal output from IC5301
respectively?
Pins (26, 27/TMDS3H_CLK_P/N), (23, 24/TMDS3H_D0_P/N),
(20, 21/TMDS3H_D1_P/N), (17, 18/TMDS3H_D2_P/N), (29, 30/
SCL3H_ SINK/SDA3H_SINK)
NO
Check the IC5301 and peripheral circuits.
YES
Is the TMDS_Rx/ I2C_SINK signal output from IC5301 input to
IC1507 (TMDS-SW)?
Pins (6,4 /TMDS3H_CLK_P/N), (8, 7/TMDS3H_D0_P/N), (11, 10/
TMDS3H_D1_P/N), (14, 13/TMDS3H_D2_P/N), (2, 1/SCL3H_
SINK/SDA3H_SINK)
NO
Check the line between IC5301 and IC1507.
YES
