Blinking In Red And Green (Flow Chart) - Pioneer PRO-1410HD Field Service And Training Manual

(4) Alternation blinking in red and green (Alarm of PDP error)
(Caution) How to reset the alarming condition
Pressing the [Input Select] key of the product, turn on the main power supply
of the main unit. In this state, keep pressing the [Input Select] key for more
than 2 seconds until alarming is canceled. Make confirmation by the method
specified below.
Blinking in red and green
Move the main power
setting for OFF → ON.
Is there alternation blinking
in red and green?
YES
Turn OFF the main power
supply.
With the [Menu] key of the
product kept pressed, turn
on the main power supply
to assume the [Voltage
Check Mode].
Is there a 3.3Vdc output at
Pin 94 of IC9501 in the
MAIN PWB? (See the
PWB Layout Diagram on
P4-20.)
NO
Turn ON the main power
supply in the state that the
AD, PD, and PH connectors
are disconnected. In this
state, are there the outputs
of Vs (170Vdc), Vd (60Vdc),
and 5Vdc at the PD/PH
connectors as specified in
the table at right? In this
case, however, no images
are generate.
YES
Test PDP Module Area.

NO
Normal
(Caution) When the main power supply is turned on with the
[Menu] key of the product kept pressed, it takes 30
seconds more to assume the state of [blinking in red and
green]. In this time period, the following voltage checks
should be carried out.
If the state of [blinking in red and green] is assumed
during this checking, take actions of [Alarm Canceling]
and [Voltage Check Mode Setup] again.
YES
The MAIN PWB is fault.
NO
The Power unit is fault.
(Caution) The voltage values of Vd and Vs and also the connector
pin numbers can differ according to the PDP. The method
of checking these voltage values is obtainable from [2.
