1 Power failure P N LB Assy
Check the power-supply voltages
(
V +5R6, V +32) of the FL.
If the presence of power is not confirmed, check the
mounting statuses of the regulator IC and its
peripheral parts for each power supply. If they are
properly mounted, then the parts may be defective.

Check the waveforms and connection of
communication line of FL in the P
N LB Assy.
• FLSCLK
• FLBK
• FLLAT
• FLSO
If no signal is output, the PA N EL CPU (IC501) may
be defective.
If output signal is no problem, FL (
V 501) may be
defective.

Communication between the Main CPU and Panel CPU has not been established.
1 Signal errors P N LB Assy Check the TSCS, TSCK, and TSI waveforms.
If the signal is not output, PA N EL CPU (IC501)
may be defective.

A voltage error
was generated.
— Check the level of the V DET signal.
If the signal level is "L", a voltage error was
generated.
2 Power failure MAI N Assy Check the V +3R3/ V +1R2 power voltages.
If power is not output, a part of the power supply
section may be defective.
3 Signal errors MAI N Assy
Check the level of the P N RDY signal
and the waveform of the TSO signal.
If the P N RDY signal level is "L" or the TSO signal
waveform is not output (fixed at either L or H), the
Main CPU (IC103) may be defective.
Shifting from the STA N DBY mode to another mode cannot be performed.

1 P N LB Assy
Check if there is loose connection on the
signal line from the PA
N EL CPU (IC501)
to the SW(S525).
If the connection up to the SW is properly made and
if the signal is not set to "L" when the SW is pressed,
the SW may be defective.
2 Signal errors P N LB Assy Check the TSCS, TSCK, and TSI waveforms.
If the signal is not output, PA N EL CPU (IC501)
may be defective.

P N LB Assy
Check the level of POWER_O N signal
(IC501-4 pin).
If the level is "L", PA N EL CPU(IC501) may be
defective.
If the level is "H", SMPS Assy may be defective.
