Checking of Sync Signal
Is the horizontal synchronized
signal on IC5001 (6) pin?
Is the vertical synchronized signal
on IC5002 (6) pin?
Is the synchronized signal is
outputted from IC5009, IC5005,
IC5006, IC5007, IC5008?
Are the timing of both vertical and
horizontal synchronized signals
correct?
Is the horizontal synchronized
signal on IC6004 (30) pin?
Is the vertical synchronized signal
on IC6004 (31) pin?
The sync signal is normal.
End of checking.
Yes
No
Check the PWB of the signal input
part.
No
Yes
Yes
Yes
Yes
No
Yes
Check each IC and the peripheral
circuit of IC.
No
Check IC6001, IC6002 and IC
peripheral circuits.
No
Set the signal source appropriately.
No
2
Is the signal generator (input
source) correct?
Yes
IC8001 and its periphery is
defective.
No

signal on IC6004 (66) pin?
Is the vertical synchronized signal
on IC6004 (64) pin?
Yes
Yes
No
Failure of IC6004 and IC
peripheral circuit.
No
