<HDMI input> No video (5)-4
HDMI: No external input video [INPUT-4]
Is INPUT-4 selected on the input select menu screen?
NO
Select INPUT-4 on the input select menu screen for
the right input signal.
YES
Does the HOT PLUG detection function?
NO
Check the line between the input terminals of SC1505
and IC1504.
Does the DDC5V signal come from pin (18) of SC1505 to pin (51) of IC1504
(HDMI_SW)?
Check IC1504 and its peripheral circuits
(pin70 of IC1504/SCL1: pin71 of IC1504, etc.).
YES
Does the HPD signal come from pin (50) of IC1504 to pin (19) of SC1505?
NO
Check the line between the pin (50) of IC1504 and the
pin (19) of SC1505.
YES
Check IC1504 and its peripheral circuits
pin70 of IC1504/SCL1: pin71 of IC1504, etc.).
Are there the TMDS signal inputs at pins (99/100) (CLK-/+), (1/2) (D0-/+), (3/4)
(D1-/+), (5/6) (D2-/+), all of IC1504?
NO
Is IC1504 (pin48/pin49) accessed by I2C, with HDMI
connected, to read the DDC_I2C SDA/SCL data?
YES
NO
Check the DDC line and its peripheral circuits.
(IC1504 and its peripherals)
Are there the all of TMDS inputs at pins (AM9/AL9) (CLK-/+), (AM10/AL10) (D0-/
+), (AM11/AL11) (D1-/+), (AM12/AL12) (D2-/+) of IC3303 (CPU)?
NO
Check the line between IC1504 and IC3303, and their
peripheral circuits.
YES
Are the LVDS signal input to the pin of P2601?
LVDS0_FPGA_D0P/N (39/40pin), LVDS0_FPGA_D1P/N (37/38pin),
LVDS0_FPGA_D2P/N (35/36pin), LVDS0_FPGA_D3P/N (30/31pin),
