Is COMP_Y signal sent to pin (2) of AV (CN116) ?
NO
Check the setting of an external input device that connects of
CN116.
Refer to “The picture doesn't appear in all modes.”
Is COMP_Y signal sent to pin (V13) of IC U401?
NO
Check the line between IC U401 and CN116.
Is the HDMI_0M_HPD detection function of pin (19) of a HDMI1
terminal (CN501) normal?
NO
Check the line between pin (W5) of IC U401 and CN501.
Refer to “The picture doesn't appear in all modes.”
Is access possible in the re-writing or exchange of EDID data of
IC U401?
Is TMDS signal input into pin ((Y9,W9)/( RX_0_2, RX_0_2B),
(V9,U9)/(
RX_0_1, RX_0_1B),(V8,V7)/( RX_0_0, RX_0_0B),
(Y7,W7)/( RX_0_C, RX_0_CB)) of IC U401?
Check the line between IC U401 and CN501.
Is the HDMI_2M_HPD detection function of pin (19) of a HDMI1
terminal (CN502) normal?
NO
Check the line between pin (J16) of IC U401 and CN502.
Refer to “The picture doesn't appear in all modes.”
NO
