Is there the COMPONENT video signal out-
put at pins (2), (4) and (6) of connector
(SC501) on the IF unit?
YES
Check the line between IC501
and SC501 (Q501 thru Q506,
etc.).
Is there the COMPONENT video signal
input at pins (2), (4) and (6) of connector
(SC1101) on the main unit?
YES
Check the SC501 and SC1101
connectors.
Is there the COMPONENT video signal
input at pins (U3)(Y), (AA1)(Pb) and
(W3)(Pr) of IC3301 (VPC)?
YES
Check the line between
SC1101 and IC3301 and their
peripheral circuits (Q2202,
Q2203, Q2206, etc.).
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)
Check the panel module.
Check the line between IC1103
and IC3301 (Q2204, Q2208,
etc.).
NO
NO
NO
NO
YES
Check IC3301 and its peripheral control cir-
cuits (IC5301, IC5302, IC8101, etc.).
Are there the MVY[7:0], MVC[7:0] and MVCLK/
MNSYNCO/MVSYNCO signal outputs from
IC8101?
Are there the MVY[7:0], MVC[7:0] and MVCLK/
MNSYNCO/MVSYNCO signal inputs at IC3301?
NO
6 – 6

YES
Check IC8101 and its peripheral
circuits.
YES
Check the line between IC8101 and
IC3301.
