Video playback failure.
Replace IC2201.
Check the V-H.SW.P. signal line.
Is 5V voltage applied at pin (36) of CCD power terminal IC2201?
Check the line between pins (23) and (24) of IC2001. (Check C2210.)
Recording and playback possible, but no colors.
FLOW CHART No. 2-15
Is there the FM input signal (about
0.4Vp-p) at pin (78) of IC2201?
Check the line between pins (78) and
(79) of IC2201.
Is there the luminance output signal
(about 0.4Vp-p) at pin (79) of IC2201?
Are there the luminance input and
output signals (about 0.25Vp-p) at
pins (13), (14) and (16) of IC2201
respectively?
Check the peripheral circuits of pins
(13), (14) and (16) of IC2201. (Check
C2203, R2201, R2202, L2204,
C2205 and R2203.)
Is there the luminance input signal
(about 0.5Vp-p) at pin (19) of IC2201?
Check the line between pins (18) and
(19) of IC2201. (Check C2206.)
Is 5V voltage applied at pin (61) of
chroma power terminal IC2201?
Check the peripheral circuits of pin
(61) of IC2201 and the PC5V line.
Is there the chroma input signal
(about 403mVp-p/Burst) at pin (46)
of IC2201?
Is there the chroma input signal
(about 508mVp-p/Burst) at pin (58)
of IC2201?
Is there the chroma output signal
(about 286mVp-p/Burst) at pin (55)
of IC2201?
Check the line between pin (55) of
IC2201 and pin (5) of IC1301.
(Check R5503 and C5510.)
Check the line between pins (46) and
(60) of IC2201. (Check C5512.)
Make sure oscillation (3.58MHz)
occurs at pins (71) and (73) of
IC2201.
Check the line between pins (35) and
(58) of IC2201. (Check R5505 and
C5515.)
Is there the chroma output signal
(about 508mVp-p/Burst) at pin (35)
of IC2201?
Is there the luminance input signal
(about 0.3Vp-p) at pin (42) of IC2201?
Check the line between pins (21) and
(42) of IC2201. (Check C2208.)
Is there the luminance input signal
(about 0.5Vp-p) at pin (26) of IC2201?
Check the line between pins (26) and
(39) of IC2201. (Check C2212.)
Is there the luminance input signal
(about 0.5Vp-p) at pin (23) of IC2201?
Is there the luminance output signal
(about 0.5Vp-p) at pin (39) of IC2201?
Is the V-H.SW.P. signal applied at pin
(81) of IC2201?
Replace IC2201.
Is the CCD control voltage of about 5V applied to pin (37) of IC2201?
Check to see if the CCD clock signal (about 7.16MHz/0.5Vp-p) is applied from pin (69) to pin (44) of IC2201.
