LC-37XD1E/RU
4 – 21
FRC circuit failure
Note: The SD signal (576i 480i) alone passes through the FRC circuit. (The HD signal does not go through.)
Does the image appear with the HD
signal, but not with the SD signal ?
Does anything unusual (which or
blackish screen, block noise, for
example) appear on the screen?
Does the image look unusual with
the power switch turned on?
YES
YES
YES
Is the power supplied to IC3301
(FRC)?
Is there the FRC-IN signal input at pins
(142) and (13) of IC3301?
Check the soldering condition.
Is there the specified RESET-A signal
input at pin (39) of IC3301(FRC)?
(60 ms delay design)
Check the connection between pin
(R22) of IC3002 (V-PRO.) and pin
(142) of IC3301 (FRC) as well as
that between pin (N20) of IC3302
and pin(13) of IC3301
YES
NO
Replace IC3301(FRC).
Check "RESET-A " signal pin(34) of
IC1710 (FPGA).
