TROUBLE SHOOTING TABLE
Check all the settings microprocessor's adjust process menu.
Do F3701 and F3702
function?
Are T701's secondary
outputs, +32V, +9V,
+5V and -8V normal?
Remove F3701 and F3702
and check the load side.
Is there short-circuiting?
Is there short-circuiting of
T3701 primary side periphery,
Q3702, Q3711 and P3706?
Replace F3701 and F3702.
Check T3701's secondary
side periphery.
Check T701's secondary
load.
Check all connection of each unit. (Refer to overall wiring diagram.)
Check T701's primary side
periphery.
Check T3701's primary side
periphery, Q3711 and their
perpheral parts.
Does F3701, F3702, F6551,
F6552, F6553 and F6554
function?
Is the pin (31) of IC4561 in
the "H" state?
Are the Q6553, Q6556, Q6559
and Q6562 short-circuiting?
Is T6551~T6557's primary
oscillator waveform normal?
Replace the fluorescent
lamp with new one and
check again.
Check the OFL line, IC14561
and their peripheral parts.
Check Q6553, Q6556,
Q6559, Q6562 and their
peripheral parts.
Check Q6551, Q6554, Q6557,
Q6560, Q6552, Q6555,
Q6558, Q6561 and
