This technical training guide will address the disassembly and adjustments of 42 and 61 inch Pioneer Plasma Display models.

This guide was designed as a servicing aid and is not intended to replace the service manual. The student should have the appropriate service manual on hand when when using this guide. Data in the service manual for this unit contains specific information on safety, parts and adjustments.

Safety information

Important safety data for this Pioneer model is contained in the service manual. Before returning the unit to the customer, complete all product safety obligations and tests. Technicians who bypass safety features or fail to carry out safety checks may expose themselves and others to possible injury, and may be liable for any resulting damages.

For more information on electronic

circuits and block diagrams refer

to the Service manual.

Lead in the solder used in this product is a known reproductive toxicant which may cause birth defects or other reproductive harm. (California Health and Safety Code Section 25249.5).

When servicing this or handling circuit boards and other components which contain solder, avoid unprotected skin contact with the solder. Also, when soldering do not inhale any smoke or fumes produced.

1. AC line attached to Power Supply.

2. Power Supply outputs a Power Mute voltage at +4.8 from Connector PM pin 5 (POMUTE). The Power Supply also outputs a +7 volt supply to the Main Microprocessor at Connector PM pin 1 (M+7).

3. The +7 volt supply now on the Main PCB goes to the RS232 PCB, Power Switch PCB and IC9503 the +5 volt regulator. Additionally the +7 volt supply returns back to the Power Supply as one of the Power Start Up signals.

4. The +5 volt regulator (IC9503) outputs to the RS232 and Power Switch PCB’s. At this time the Main Microprocessor sets the state to Standby and the front panel LED lights Red.

5. From Standby pressing the Power button will send a +5 volt signal to the Main Microprocessor from the Power Switch PCB Connector PW pin 2 (POIN).

6. The Main Microprocessor outputs the Power On +5 volt signal to the Power Supply from Connector PM pin 3 (POWER). At this time the Power Relay engages.

7. The Power Supply upon receiving the Power On Signal supplies all other secondary supply voltages.

8. After secondary supply voltages come up the power supplies for VS (170) and VD (65) turn on.

9. NOTE: Panel Alarm Input Line can shutdown the Power Supply (Low Normal).

Notes: · Be sure not to drop a screwdriver or screw on a PKG or a cable.

· When removing/reattaching a screw, be sure not to leave any tiny metal shavings, because they may cause a failure.

· Before removing Signal Relay PKGs, remove the heat sink.

· Be sure not to apply any stress to a PKG, connector, or cable when reattaching them.

· Reattach Signal Relay PKGs before reattaching the heat sink.

METHOD OF ADJUSTMENTS

PDP-614MX & PRO-1410HD

■Adjusting conditions

Adjustments should be carried out in the procedures of A to C specified below. However, any adjustments other than the items A to C below are not required.

A. When the “PDP module (PDP-NP61C2MF01)” is replaced, adjustments

should conform to the adjusting items of [1 and 2] specified below.

B. When the “POWER UNIT” is replaced, adjustments should conform to the

adjusting item of [2] specified below.

C. When the “MAIN PWB” is replaced, adjustments should conform to the

adjusting item of [3] specified below.

■Adjusting items

1. Clearing of the usage time (Using the remote control)

(1) Press the keys in the order of [POWER ON] → [POWER ON] → [EXIT] → [DISPLAY] in order to

enter the factory adjustment menu.

(2) Press the [MENU/ENTER] key to select the [USAGE TIME] menu (8/11). Then, the integrated time

[34567 (hours)] (example) accumulated till the present time is displayed when the main power supply is turned on (except for the standby mode).

2. Adjustment of the power unit (Using a screwdriver for general-purpose

32

adjustments)

2-1. Adjustment of the Vs voltage

(1) Enter a color bar input by means of either video signal of VIDEO input, or DVD/HD input, or RGB

input, and turn on the power switch of the main unit.

(2) Turn the volume control (RV6) in the power unit and make adjustments until the voltages of CH2 and

CH1 (D, GND) of the power unit attain the voltage values specified for the PDP (Vs value of the voltage regulation indicator label on below the figure) ±1V.

2-2. Adjustment of the Vd voltage

(1) Enter a color bar input by means of either video signal of VIDEO input, or DVD/HD input, or RGB

input, and turn on the power switch of the main unit.

(2) Confirm that the voltages of CH4 and CH1 (D, GND) of the power unit are maintained at the voltage

values specified for the PDP (Vd value of the voltage regulation indicator label on below the figure) ±1V.

Otherwise, turn the volume control (RV5) until the voltage attains the voltage values specified for the PDP (Vd value of the voltage regulation indicator label on below the figure) ±1V.

2-3. Adjustment of the +5V voltage

(1) Display a color bar by means of either video signal of VIDEO input, or DVD/HD input, or RGB input.

(2) Confirm that the voltages of CH3 and CH1 (D, GND) of the power unit are maintained at “5.15 ±

0.1V”. Otherwise, turn the volume control (RV2) until the voltage attains “5.15 ± 0.1V”.

Cause/Countermeasure: ① Open or contact failure of Data flexible Cable⇒Clean,

Reconnect or exchange connector.

② Failure in Data IC⇒Replace PDP.

Cause/Countermeasure:

①Failure in Scan IC on Scan Relay Board⇒Exchange Scan Relay Board. ②Open or contact failure of Scan Flexible Cable (CN01-CN04) at output side of Scan Relay Board (U, D)⇒

Clean, Reconnect or exchange connector.

③Contact failure of connector between Scan Board and Scan Relay Board⇒ Clean, Reconnect or

exchange connector.

④Short between terminals of Scan IC due to screw dust⇒ Clean around the terminals.

Cause/Countermeasure: ①Open or contact failure of connector between Data Relay Board and Digital Board/High Voltage Board⇒ Clean, Reconnect or

exchange connector.

②Open or contact failure of multiple Data flexible Cables⇒ Clean,

Reconnect or exchange connector.

③Failure in Data Relay Board ⇒Exchange the Data Relay Board. ④Failure in multiple Data IC⇒Replace PDP.

METHOD OF ADJUSTMENTS

PDP-424MV

■Adjusting conditions

Adjustments should be carried out in the procedures of A to C specified below. However, any adjustments other than the items A to C below are not required.

A. When the “PDP module” is replaced, adjustments should conform to the

adjusting items of [1 and 2] specified below.

B. When the “POWER UNIT” is replaced, adjustments should conform to the

adjusting item of [2] specified below.

C. When the “MAIN PWB” is replaced, adjustments should conform to the

adjusting item of [3] specified below.

■Adjusting items

1. Clearing of the usage time (Using the remote control)

(1) Press the keys in the order of [POWER ON] → [POWER ON] → [EXIT] → [DISPLAY] in order to

enter the factory adjustment menu.

(2) Press the [MENU/ENTER] key to select the [USAGE TIME] menu (8/11). Then, the integrated time

[34567 (hours)] (example) accumulated till the present time is displayed when the main power supply is turned on (except for the standby mode).

2-1. For the PX-42VM5/42VP5/42VR5,PX-42XM3/42XR3 Series

2-1-1. Adjustment of the Vs voltage

(1) Enter a color bar input by means of either video signal of VIDEO input, or DVD/HD input, or RGB

input, and turn on the power switch of the main unit.

(2) Turn the volume control (RV203) in the power unit and make adjustments until the voltages of TP204

and TP205 (D, GND) of the power unit attain the voltage values specified for the PDP (Vs value of the voltage regulation indicator label on below the figure) ±1V.

2-1-2. Adjustment of the Vd voltage

(1) Enter a color bar input by means of either video signal of VIDEO input, or DVD/HD input, or RGB

input, and turn on the power switch of the main unit.

(2) Turn the volume control (RV204) in the power unit and make adjustments until the voltages of TP206

and TP205 (D, GND) of the power unit attain the voltage values specified for the PDP (Vd value of the voltage regulation indicator label on below the figure) ±1V.

2-1-3. Adjustment of the +5V voltage

(1) Display a color bar by means of either video signal of VIDEO input, or DVD/HD input, or RGB input.

(2) Confirm that the voltages of TP203 and TP205 (D, GND) of the power unit are maintained at “5.15 ±

0.1V”. Otherwise, turn the volume control (RV201) until the voltage attains “5.15 ± 0.1V”.
