IC1507(TMDS-SW).
Is the Hot plug detection function output from pin (19) of the HDMI-
3(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.
Is EDID data pins(11)/SCL1, (10)/SDA1 of IC1504(FRAM) accessed, and
is it read from pins(15, 16) of a HDMI-1(SC1502)?
Is EDID data pins(14)/SCL2, pin(13)/SDA2 of IC1504(FRAM) accessed,
and is it read from pins(15, 16) of a HDMI-2(SC1501)?
NO
Is access possible in the exchange of IC1504?
Is EDID data pins(5)/SCL3, (6)/SDA3 of IC1504(FRAM) accessed, and is
it read from pins(15, 16) of a HDMI-3(SC5301)?
NO
YES
<HDMI-1/2>
Check the peripheral circuit of SC1501, SC1502, IC1504
and IC1507.
<HDMI-3>
Check the peripheral circuit of SC5301, IC1504 and
IC5301.

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,
