<SUB VIDEO>
No tuner (U/V) output.
IIs video signal output from pin (17) (video
output terminal) of the tuner?
Check the tuner and its peripheral circuit.
Is the signal input to pin (7) of IC1103? Check between the tuner and IC1103.
Is the signal output from pin (5) of IC1103? CheckIC1103 and its peripheral circuit.
Is the signal input to pin (17) of IC3800
(AVSWITCH)?
Check betweenIC1103 and IC3800.
No tuner B (U/V) output.
IIs video signal output from pin (17) (video
output terminal) of the TU1102?
Check the tuner and its peripheral circuit.
Is the signal input to pin (1) of IC1103? Check between the tuner and IC1103.
Is the signal output from pin (3) of IC1103? Check IC1103 and its peripheral circuit.
Is the signal input to pin (19) of IC3800
(AVSWITCH)?
Check betweenIC1103 and IC3800.
< Tuner (U/V) > input
Are the main video signal and sub video signal output to pins (60) and (56) of IC3800 respectively?
Are the main video signal and sub video signal output to pin (2) of IC402 and pin (2) of IC501?
<MAIN VIDEO>
Check between IC402 and IC403.
Is there video signal input at pin (135) of
IC403 (MAIN VIDEO DEC)?
Are there digital video signal outputs at pins
(56)~(69) and (92)~(106) of IC403?
Check IC403 (MAIN VIDEO DEC) and the
peripheral circuits.
No video output (3)
Check IC3800 (AV SWITCH) and the
peripheral circuits.
Check between IC3800 and IC402/IC501.
Is there video signal input at pin (135) of
IC502 (SUB VIDEO DEC)?
Check between IC501 and IC502.

Is the digital video signal input to pins (51) to (100) and pins (1) to (10) of IC3201? (Check the signal terminals only.)
Is the digital video signal output from pins (39) to (49) of IC3201? (Check the signal terminals only.)
Replace the main PWB, or check between
IC403/IC502 and IC3201.
Check IC3201 (LVDS Tx) and the
peripheral circuits.
Is the digital video signal output from pins (3) to (16) of SC3200? (Check the signal terminals only.)
Check between IC3201 and SC3200.
No abnormality is found up to main PWB. Check the TMDS PWB.
