LC-52SE94U/LC-52SE941U/LC-65SE94U
6 – 7
No video (6)
PC: No external input video [INPUT-7]
Is INPUT-7 selected on the input select menu screen?
YES
NO
Select INPUT-7 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 circuits (IC2202 and its peripher-
als).
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 the LVDS signal outputs at the LVDS 1st channel and 2nd channel of IC8001?
LVDS_TX_0_DATA0_P/N(C7/B7), LVDS_TX_0_DATA1_P/N(E7/D7),
LVDS_TX_0_DATA2_P/N(C6/B6), LVDS_TX_0_DATA3_P/N(C5/B5),
LVDS_TX_0_DATA4_P/N(E5/D5), LVDS_TX_0_CLK_P/N(E6/D6),
LVDS_TX_1_DATA0_P/N(B4/A4), LVDS_TX_1_DATA1_P/N(E4/D4),
LVDS_TX_1_DATA2_P/N(B3/A3), LVDS_TX_1_DATA3_P/N(B1/B2),
LVDS_TX_1_DATA4_P/N(F5/F6), LVDS_TX_1_CLK_P/N(C2/C3),
NO
Check IC8001 and its peripheral circuits.
(IC8151 thru IC8154, etc.)
YES
Check the panel module.
