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 TS data (FECLK, FESTR_PSYNC, FED_D, FEVAL_DEN)
input to IC8101(DIGITAL AV DECODER & MAIN CPU & VIDEO
PROCESSER)?
NO
Check the line between IC7508 and IC8101.
(IC7503, etc.)
YES
Refer to “The picture doesn't appear in all modes.”
