(2) Flashing in red (Temperature error detected)
Is the potential 0V at Pin 10
of IC9806 (MAIN PWB)?
YES
Are TH1 in the POWER unit
and its peripheral circuits out
of order?
(Caution) How to reset the alarm:
• Turn the power circuit off and on at the main power supply, remote control, or the wall outlet.
(3) Reciprocally flashing in green and red (Cracks in the panel detected)
Is the potential 0V at Pin 100
of IC9501 (MAIN PWB)?
YES
Is the potential 0V at Pin 2 of
IC9505 (MAIN PWB)?
YES
Failure in the periphery of the
PDP module circuit.
(Caution) How to reset the alarm:
• Turn the power circuit [ON], with the input changeover key of the product kept pressed. In this state,
keep on pressing the input changeover key for more than 2 seconds.
