LC-46D82U/LC-52D82U
Check the DDC line and its peripheral circuits
(IC1701 (EEPROM) and its peripherals).
Does the signal come from pins (34 and 35) (CLK±), (31 and 32) (D0±),
(28 and 29) (D1±), and (25 and 26) (D2±) of IC1702 to pins (39 and 40),
(43 and 44), (47 and 48), and (51 and 52) of IC1510?
Check IC1702, IC1510 and their peripheral
circuits.
YES
Are there the U3VINY[7:0], U3VINR[7:0], U3VINPBPR[7:0], U3VDIN, U3HDIN, U3DEIN
and U3VINCLK signal outputs from IC1510?
Are there the U3VINY[7:0], U3VINR[7:0], U3VINPBPR[7:0], U3VDIN, U3HDIN, U3DEIN
and U3VINCLK signal inputs at IC3301 (VPC)?
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/

Check the DDC line and its peripheral cir-
cuits (IC1501 (EEPROM) and its
peripherals).
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
(58 and 59), (62 and 63), (66 and 67), and (70 and 71) of IC1510?
Check IC1507, IC1510 and their periph-
eral circuits.
YES
Check IC1510 and its peripheral circuits.
NO
Check the line between IC1510 and
IC3301.
NO
Check IC3301 and its peripheral control
circuits (IC3501, IC3502, IC8101, etc.).
NO
NO
