4 – 7
No picture on the display (3)
Does not the picture come out when DTV is received?
Is the prescriptive voltage supplied a power supply terminal of a
TUNER circuit and IC7508 (COFDM - DEMOD)?
(Refer to a circuit diagram.)
NO
Each power supply circuit is checked.
(IC7502, IC9607, IC9604, etc.)
YES
Is IF signal sent from pins(16, 17) of TUNER(TU7501) to pins(40,
39) of IC7508(COFDM-DEMOD.)?
NO
Check the tuner, IC7508 and their peripheral circuits.
Replace as required.
YES
Check whether I2C signal normally communicates between
TU7501 and IC7508 (COFDM - DEMOD.)
NO
YES
Does X7501(20.25MHz) oscillate?
NO
Check X7501 and its peripheral circuits.
YES
Is TS data (FECLK, FESTR_PSYNC, FED_D, FEVAL_DEN)
being output from IC7508 to IC8101(DIGITAL AV DECODER &
MAIN CPU & VIDEO PROCESSER)?
NO
Check whether a control signal is normal between IC7508 and
IC9101(CPLD). (FE_RST, N_TUNER_INT, FERR_UNCOR,
AGCSEL)
YES
Is the TS data input to pin (AE4/FERR_UNCOR), (AG5/FECLK),
(AF4/FESTR_PSYNC), (AA4/FED_D) and (AF5/FEVAL_DEN) of
IC5001(H.264_DECODER)?
NO
Check the line between IC7508 and IC5001.
YES

N), (T33, T34/ TMDSH_D0_P/N), (R33, R34/ TMDSH_D1_P/N),
and (P33, P34/ TMDSH_D2_P/N) of IC5001?
NO
Check IC5001 and its peripheral circuits.
YES
Is the TMDS signal input to pin (39, 38/ TMDSH_CLK_P/N), (42,
41/ TMDSH_D0_P/N), (45, 44/ TMDSH_D1_P/N), and (48, 47/
TMDSH_D2_P/N) of IC5301(TMDS_SW.)?
NO
Check the line between IC5001 and IC5301.
YES
Is the TMDS signal output from pin (26, 27/ TMDS3H_CLK_P/N),
(23, 24/ TMDS3H_D0_P/N), (20, 21/ TMDS3H_D1_P/N), and
(17, 18/ TMDS3H_D2_P/N) of IC5301?
NO
Check IC5301 and its peripheral circuits.
YES
Is the TMDS signal input to pin (6, 4/ TMDS3H_CLK_P/N), (8, 7/
TMDS3H_D0_P/N), (11, 10/ TMDS3H_D1_P/N), and (14, 13/
TMDS3H_D2_P/N) of IC1507(TMDS_SW.)?
NO
Check the line between IC5301 and IC1507.
YES
Is the TMDS signal output from pin (26, 27/ TMDS_CLK_P/N),
(23, 24/ TMDS_D0_P/N), (20, 21/ TMDS_D1_P/N), and (17, 18/
TMDS_D2_P/N) of IC1507?
NO
Check IC1507 and its peripheral circuits.
YES
Is the TMDS signal input to pin (K1, K2/ TMDS_CLK_P/N), (L1,
L2/ TMDS_D0_P/N), (M1, M2/ TMDS_D1_P/N), and (N1, N2/
TMDS_D2_P/N) of IC8101(DIGITAL AV DECODER & MAIN
CPU & VIDEO PROCESSER)?
NO
Check the line between IC1507 and IC8101.
YES
