Is there signal at pin
(30) of IC2201?
Is there signal at pin
(41) of IC1301?
Check the line
between pin
(41) of IC1301
and pin (30) of
IC2201.
Are there the
I2C clock and
data signals at
pins (62) and
(63) of
IC2201?
Replace
IC2201.
Check the
tuner/IF circuit
(TU261) or
J405, J401
and their
peripheral
parts.
Is there the luminance
input signal (about 0.5Vp-
p) at pin (19) of IC2201?
Is there the luminance
input signal (about 0.3Vp-
p) at pin (42) of IC2201?
Is there signal at pin
(52) of IC2201?
Is 5V voltage applied
at pins (12), (36),
(38), (40), (41), (43),
(61), (67), (90) and
(96) of IC2201?
Is there the luminance
input signal (about 0.5Vp-
p) at pin (26) of IC2201?
Check the line
between pins
(62)/(63) of
IC2201 and
pins (57)/(56) of
IC2001.
Check the
YC5V line.
Check the cylinder. Replace as required.
Make sure that YC5V is applied at pin (90) of IC2201.
Check the line between
pins (18) and (19) of
IC2201. (Check C2206.)

pin (61) of chroma power
terminal IC2201?
Is there the chroma input
signal (about 143mVp-p
/Burst) at pin (46) of
IC2201?
Check the peripheral
circuits of pin (61) of
IC2201 and the YC5V line.
Check the line between
pins (46) and (60) of
IC2201. (Check C5512.)
Is there the luminance
output signal (about 0.5Vp-
p) at pin (39) of IC2201?
Is there the chroma input
signal (about 180mVp-p
/Burst) at pin (58) of
IC2201?
Check the line between
pins (35) and (58) of
IC2201. (Check R5505
and C5515.)
Is 5V voltage applied at
pin (36) of CCD power
terminal IC2201?
Make sure that the CCD
clock signal (about
7.16MHz/0.5Vp-p) is
applied from pin (69) to pin
(44) of IC2201.
Is there the chroma
output signal (about
180mVp-p/Burst) at pin
(35) of IC2201?
Make sure oscillation
(3.58MHz) occurs at pins
(71) and (73) of IC2201.
Is there the luminance
input signal (about 0.5Vp-
p) at pin (23) of IC2201?
Are there the luminance
input and output signals
(about 0.5Vp-p) at pins
(13) and (14) of IC2201
respectively?
Check the line between
pins (23) and (24) of
IC2201. (Check C2210.)
