4 – 15
[External input EXT4] No picture on the display (9)
Does not the picture of the DVI(ANALOG) video signal input to EXT4(15pin-D-SUB terminal) go out?
YES
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)? NO Check the connection and setup with the external DVI devices.
YES
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)? NO Is access possible in the exchange of IC1201?
YES
NO
Check the circumference circuit of SC1201, IC1201.
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)? NO Check the line between SC1201 and IC3001.
(IC1941,etc)
YES
Refer to “The picture doesn't appear in all modes.”
[External input EXT5] No picture on the display (10)
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? NO Check the connection of J1401 and the external input device.
YES
Is COMPONENT video signal input into pin(1)/Y, (6)/Pb,
(9)/Pr of IC1401(VIDEO_BUFFER)? NO Check the line between J1401 and IC1401.
YES
Is COMPONENT video signal input into pin(180), (179),
(181) of IC3001(MAIN_MICON) from pin(20)/Y, (18)/PB,
(16)/PR of IC1401? NO Check the line between IC1401 and IC3001.
YES
