LC-40/46/52/60LE810UN (1st Edition) No video (5)-2 HDMI: No external input video [INPUT-6] HDMI: No external input video [INPUT-7] Is INPUT-6 selected on the input select menu screen? Is INPUT-7 selected on the input select menu screen? NO Select INPUT-6 on the input select menu screen for the right input signal. YES Does the HOT PLUG detection function? Does the DDC5V signal come from pin (18) of SC1501 to pin (36) of IC1504 (HDMI_SW)? NO Select INPUT-7 on the input select menu screen for the right input signal. YES Does the HOT PLUG detection function? Does the DDC5V signal come from pin (18) of SC1505 to pin (32) of IC1504 (HDMI_SW)? YES NO Check the line between the input terminals of SC1501 and IC1504. Check IC1504 and its peripheral circuits. (SDA0_400K: pin53 of IC1504/SCL0_400K: pin54 of IC1504, etc.). Does the HPD signal come from pin (35) of IC1504 to pin (19) of SC1501? YES NO Check the line between the input terminals of SC1505 and IC1504. Check IC1504 and its peripheral circuits (pin53 of IC1504/SCL1: pin54 of IC1504, etc.). Does the HPD signal come from pin (31) of IC1504 to pin (19) of SC1505? YES NO Check the line between the pin (31) of IC1504 and the pin (19) of SC1501. Check IC1504 and its peripheral circuits (SDA0_400K: pin53 of IC1504/SCL0_400K: pin54 of IC1504, etc.). Are there the TMDS signal inputs at pins (1/2) (CLK-/+), (3/4) (D0-/ +), (5/6) (D1-/+), (7/8) (D2-/+), all of IC1504? YES NO Check the line between the pin (41) of IC1504 and the pin (19) of SC1505. Check IC1504 and its peripheral circuits pin53 of IC1504/SCL1: pin54 of IC1504, etc.). Are there the TMDS signal inputs at pins (65/66) (CLK-/+), (67/68) (D0-/+), (69/70) (D1-/+), (71/72) (D2-/+), all of IC1504? NO Is IC1504 (pin33/pin34) accessed by I2C, with HDMI connected, to read the DDC_I2C SDA/SCL data? NO Is IC1504 (pin29/pin30) accessed by I2C, with HDMI connected, to read the DDC_I2C SDA/SCL data? NO Check the DDC line and its peripheral circuits. (IC1504 and its peripherals). YES YES Are there the TMDS signal inputs at pins (AJ6/AK6) (CLK-/+), (AJ7/AK7) (D0-/+), (AJ8/ AK8) (D1-/+), (AJ9/AK9) (D2-/+), all of IC3302 (CPU)? NO Check the DDC line and its peripheral circuits. (IC1504 and its peripherals) NO Check IC1504, IC3302 and their peripheral circuits. YES YES Are the LVDS signal outputs at the LVDS 1st channel and 2nd channel of IC3302? NO LVDS_TX_0_DATA0_P/N (C14/D14), LVDS_TX_0_DATA1_P/N (C15/D15), LVDS_TX_0_DATA2_P/N (C16/D16), LVDS_TX_0_DATA3_P/N (C18/D18), LVDS_TX_0_DATA4_P/N (C19/D19), LVDS_TX_0_CLK_P/N (C17/D17), LVDS_TX_1_DATA0_P/N (A14/B14), LVDS_TX_1_DATA1_P/N (A15/B15), LVDS_TX_1_DATA2_P/N (A16/B16), LVDS_TX_1_DATA3_P/N (A18/B18), LVDS_TX_1_DATA4_P/N (A19/B19), LVDS_TX_1_CLK_P/N (A17/B17). Check IC3302 and its peripheral circuits. (IC3501/IC3502, etc.) YES Check the panel module. 6 - 6
