(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.

1 For the PD-5030
Blinking in red and green

Move the main power setting for OFF � ON. NO Is there alternation blinking in red and green? YES Turn OFF the main power supply. (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. NO Is there a 3.3Vdc output at Pin 94 of IC9501 in the MAIN PWB? (See the PWB Layout Diagram on P4-20.) YES 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 generated. YES Vs The PDP is fault. PD-5030 Vd GND 5Vdc GND PD-9pin PD-7pin PD-5pin PH-1pin PH-3pin The Power unit is fault. The MAIN PWB is fault. Normal

With the [Menu] key of the product kept pressed, turn on the main power supply to assume the [Voltage Check Mode].
