LC-32RD8E/S/RU-BK/GY (1st Edition)
Does not the picture of the DVI(ANALOG) video signal input to EXT4(15pin-D-SUB terminal) go out?
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 (SC1201)?
Is EDID data pin (6)/SCL, (5)/SDA of IC1201(EEPROM)
accessed, and is it read from pin (15),(12) of a DVI ter-
minal(SC1201)?
Are the video signal and the synchronized signal input
from pin(174, 173, 172)/(R, G, B), pin(171, 47)/(H, V) of
IC3001 (MAIN_MICON)?
Refer to "The picture doesn't appear in all modes."
Does not the picture of the component video signal input to EXT5 go out?
Is COMPONENT video signal input into pin(3)/Y, (5)/Pb,
(7)/Pr of the input terminal J1401?
Is COMPONENT video signal input into pin(1)/Y, (6)/Pb,
(9)/Pr of IC1401(VIDEO_BUFFER)?
Is COMPONENT video signal input into pin(180), (179),
(181) of IC3001(MAIN_MICON) from pin(20)/Y, (18)/PB,
(16)/PR of IC1401?
Refer to "The picture doesn't appear in all modes"
