LC-37D90U
6 – 10
Is IC1505 (EEPROM) accessed by I2C, with DVI connected, to read the DDC_I2C CLOCK/DATA data?
NO
Does the signal come from pins (34 and 35) (CLK±), (31 and 32)
(D0±), (28 and 29) (D1±), and (25 and 26) (D2±) of IC1507 to pins
(50 and 51), (54 and 55), (58 and 59), and (62 and 63) of IC1508?
Check the DDC line and its peripheral circuits (IC1505
(EEPROM) and its peripherals).
YES
NO
Check IC1507, IC1508 and their peripheral circuits.
Are there the U3VINY[7:0], U3VINR[7:0], U3VINPBPR[7:0], U3VDIN, U3HDIN,
U3DEIN and U3VINCLK signal outputs from IC1508?
YES
NO
Check IC1508 and its peripheral circuits.
Are there the U3VINY[7:0], U3VINR[7:0], U3VINPBPR[7:0], U3VDIN, U3HDIN,
U3DEIN and U3VINCLK signal inputs at IC3301 (CPU_H8)?
YES
NO
Check the line between IC1508 and IC3301.
Is there the LVDS signal output at the LVDS 1st channel and 2nd channel of IC3301?
TA2_P/M(AJ30/AK30), TB2_P/M(AJ29/AK29), TC2_P/M(AJ28/AK28), TD2_P/M(AJ26/AK26), TE2_P/M(AJ25/AK25), TF2_P/M(AJ24/AK24),
TCLK2_P/M(AJ27/AK27), TA1_P/M(AB29/AB30), TB1_P/M(AC29/AC30), TC1_P/M(AD29/AD30), TD1_P/M(AF29/AF30), TE1_P/M(AG29/AG30),
TF1_P/M(AH29/AH30), TF1_P/M(AH29/AH30), TCLK1_P/M(AE29/AE30)
YES NO
Check the panel module. Check IC3301 and its peripheral control circuits (IC5301,
IC5302, IC8101, etc.).
