Does not the picture of the DVI(ANALOG) video signal input to INPUT7(15pin-D-SUB terminal) go out?
MAIN_UNIT:
Are the video signal and the synchronized signal input from pin
(1, 2, 3)/(R, G, B), (13 and 14)/(V, H) of input terminal D-SUB
(SC1504)?
Are the video signal and the synchronized signal input from pin
(U8, Y7, W10)/ (R, G, B), pin (V10, U10)/(H, V) of IC3301 (VIDEO
B
PROCESSOR)?
Refer to "The picture doesn't appear in all modes."

signal from pin (7) of the input terminal J508 normal?
Is COMPONENT signal output into pin (6), (8), (10) of the con-
D
nector SC501 from pin (60)/Y, (59)/PB, (58)/PR of IC506?
MAIN UNIT:
