Page 3: Service Safety
SERVICE SAFETY Safety cautions The matters to be observed without fail are explained below. These matters are indispensable for the prevention of an accident during the maintenance servicing, the “security of products” after the completion of servicing work, and the “prevention of the repeated occurrence of similar fault.” (1) The degree of danger and material damage, caused as a result of wrong use by disregarding the contents of the display”...
Page 4 • For the maintenance servicing, safety inspection is needed in accordance with the check list. • Inspection should be carried out according to the check list shown below, in regard to safety inspection before and after repairing, authentic repair, and explanation to the user. (Method of insulation check) Mount a PDP module on the product to complete it.
Page 5 CAUTION • Observe the caution matter, without fail CAUTION • The caution matters of given in the instruction manuals, etc., must be observed, without fail. • Do not give shocks and vibration. • The panel surface (display plane) of the filter and the PDP module is made of glass. If any shocks or vibration is applied, it may be broken and the scattered glass chips will be a cause of injury.
Page 6 does not get any shock or stress. If one touches the connector of the flexible cable exposed to the rear side of the PDP module, there is danger of causing a poor contact. As such, it must be handled with utmost care. In addition, the flexible cable is very weak in mechanical strength.
Page 7: Troubleshooting
TROUBLESHOOTING • Problems in the power supply, such as “Failure in Power ON” or “LED flashing or lighting (alarm display)” → 1. Go to Power failure (P3-2). • Problems in the images, such as “No pictures available” → 2. Go to Image errors (P3-8). •...
Page 8: Power Failure
1. Power failure (Caution) If any abnormality is sensed in such a manner that the (1) The power supply is not turned on. LED flashes or lights, all the power lines other than those of 7Vdc (M+7V) and 5Vdc (M+5V) are automatically turned off in about 10 seconds.
Page 9 (2) Blinking in green Alarm of temperature sensor error Blinking in green (intervals of 2 seconds) Turn off the main power supply. Pressing the [MENU] key of the product, turn on the main power supply to cancel alarming. FAN SET FAN SET Press the remote control keys in the sequen- tial order of [MENU] [MUTE] [EXIT] [SLEEP]...

Page 11 (3) Blinking in red (Alarm of temperature error) Since the internal temperature is too high in the product, the temperature protector has been actuated. In such a case, the following actions should be taken immediately: 1. Turn off the main power supply and pull out the power cord from the wall outlet. 2.
Page 12 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. For the PD-5030 Blinking in red and green Move the main power setting for OFF →...
Page 13 (5) Lighting in green, and then in red (Alarm of power voltage error) Unlike [lighting in red] in the STANDBY mode, [lighting in green] continues for about 30 seconds without any output of images and audio signals. Since then, the mode turns into [lighting in red]. (Caution) How to reset the alarming condition Lighting in red The alarming condition can be reset when an OFF→...
Page 14 2. Image errors (Caution) Typical abnormal images are shown below. All errors do not always fall on these error samples. (1) Image burn and deterioration in brightness Residual images are seen with- out signal entry. This is not a fault. No signal Deterioration in brightness This is not a fault.

Page 21 3. Audio errors (Caution) In regard to the method of audio input setting, refer to the specifications and the instruction manual to confirm that all the setting is free from errors. Since then, troubleshooting can be carried out. It must be noted that the protector functions and no audio output is available if the opposing electrodes of the speaker output or the speaker output and the ground (GND) are short-circuited.
Page 22 4. Remote control not effective (1) The wired remote control is not effective. When a single item is used (Caution) The wired remote control is not effective if the setting of [PLE LINK], [Repeat TIMER], or [IR REMOTE] is ON, or if the setting of [ID NUMBER] has been made.
Page 23 (2) The wireless remote control is not effective. (Caution) Since the detection of “wired” or “wireless” is conducted for the remote control through the remote terminal, it is necessary to pull out the remote control cable from the remote terminal, without fail. Troubleshooting should be carried out after confirming that “IR REMOTE”...
