SAFETY INFORMATION

A	Leakage Current Cold Check
	With the AC plug removed from an AC power source, place a
	jumper across the two plug prongs. Turn the AC power switch on.
	Using an insulation tester (DC 500V), connect one lead to the
	jumpered AC plug and touch the other lead to each exposed metal
	part (input/output terminals, screwheads, metal overlays, control
	shafts, etc.), particularly any exposed metal part having a return
	path to the chassis. Exposed metal parts having a return path to
	the chassis should have a minimum resistor reading of 4MΩ. The
	below 4MΩ resistor value indicate an abnormality which require
	corrective action. Exposed metal parts not having a return path to
B	the chassis will indicate an open circuit.
	Leakage Current Hot Check
	Plug the AC line cord directly into an AC power source (do not
	use an isolation transformer for this check).
	Turn the AC power switch on.
	U s i n g a " L e a k a g e C u r r e n t Te s t e r ( S i m p s o n M o d e l 2 2 9

	the cabinet (input/output terminals, screwheads, metal overlays,
	control shaft, etc.), particularly any exposed metal part having a
	return path to the chassis, to a known earth ground (water pipe,
	conduit, etc.). Any current measured must not exceed 1mA.

PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in PIONEER set have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual.

Electrical components having such features are identified by marking with aon the schematics and on the parts list in this Service Manual.

The use of a substitute replacement component which dose not h av e t h e s a m e s a f e t y c h a r a c t e r i s t i c s a s t h e P I O N E E R recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire or other hazards.

Product Safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current PIONEER Service Manual. A subscription to, or additional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER.

[Important Check Points for Good Servicing]

In this manual, procedures that must be performed during repairs are marked with the below symbol. Please be sure to confirm and follow these procedures.

1. Product safety

Please conform to product regulations (such as safety and radiation regulations), and maintain a safe servicing environment by following the safety instructions described in this manual.

1 Use specified parts for repair.

Use genuine parts. Be sure to use important parts for safety.

2 Do not perform modifications without proper instructions.

Please follow the specified safety methods when modification(addition/change of parts) is required due to interferences such as radio/TV interference and foreign noise.

3 Make sure the soldering of repaired locations is properly performed.

When you solder while repairing, please be sure that there are no cold solder and other debris.

Soldering should be finished with the proper quantity. (Refer to the example)

4 Make sure the screws are tightly fastened.

Please be sure that all screws are fastened, and that there are no loose screws.

5 Make sure each connectors are correctly inserted.

Please be sure that all connectors are inserted, and that there are no imperfect insertion.

6 Make sure the wiring cables are set to their original state.

Please replace the wiring and cables to the original state after repairs.

In addition, be sure that there are no pinched wires, etc.

7 Make sure screws and soldering scraps do not remain inside the product.

Please check that neither solder debris nor screws remain inside the product.

8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.

Damaged power cords may lead to fire accidents, so please be sure that there are no damages.

If you find a damaged power cord, please exchange it with a suitable one.

9 There should be no spark traces or similar marks on the power plug.

When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary.

0 Safe environment should be secured during servicing.

When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely.

2. Adjustments

A

B

C

D

To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification. Adjustments should be performed in accordance with the procedures/instructions described in this manual.

3. Lubricants, Glues, and Replacement parts	E
Use grease and adhesives that are equal to the specified substance.
Make sure the proper amount is applied.

4. Cleaning

For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper cleaning should be performed to restore their performances.

5. Shipping mode and Shipping screws

To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be

installed before shipment. Please be sure to follow this method especially if it is specified in this manual. F

1. CONTRAST OF MISCELLANEOUS PARTS

NOTES: Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.

The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation.

Screws adjacent to mark on product are used for disassembly.

Reference Nos. indicate the pages and Nos. in the service manual for the base model.

For the applying amount of lubricants or glue, follow the instructions in this manual. (In the case of no amount instructions, apply as you think it appropriate.)

When ordering resistors, first convert resistance values into code form as shown in the following examples.

Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,

and K=10%).	56

3. DIAGNOSIS INFORMATION

3.1 THE FLOW OF DIAGNOSIS

A1. Abnormality in power supply

•Refer to the "7.1.3 TROUBLESHOOTING" on ARP3340 (PDP-425CMX : Page 128).

	No power
	Turn the power off at the Main
	Power Switch then back on.
	Is the POWER/STANDBY	NO
	indicator lit?
B	YES

See "Other causes for shutdown" of "Failure Diagnosis by LEDs."

Note: When an abnormality is detected and indicated by LEDs' flashing or lighting, all power-supply lines, except for the 7-V DC (M+7 V) and 5-V DC (M+5 V) lines, will be automatically shut off after about 10 seconds. When you are going to check the power-supply lines other than the 7-V DC (M+7 V) and 5-V DC (M+5 V) lines, place a tester to a measurement point beforehand then check the line.

When POWER/SATNDBY indicator turns on red, perform the power-on operation with the remote control unit or the RS232C command.

Is AC power supplied to the	NO
AC connector (power cord)?	The POWER switch or power cord is defective.
YES
Is 6.8 V DC output from Pin 1	NO
of the PM connector?

YES

C

Failure in the LED PWB (failure in D2402 or CN2401) or in the COMM SLOT IF (failure in the line for CN2301 or CN2303) or in the MAIN PWB (failure in the line for CN9010).

5. ADJUSTMENT

A

1.At shipment, the unit is adjusted to its best conditions. Normally, it is not necessary to readjust even if an assembly is replaced. If the adjustment is shifted or if it becomes necessary to readjust because of part replacement, etc., perform the adjustment as described below.

2.Any value changed in Service/Factory mode will be stored in memory as soon as it is changed. Before readjustment, take note of the original values for reference in case you need to restore the original settings.

3.Use a stable AC power supply.

5.1 ADJUSTMENT REQUIRED WHEN THE SET IS REPAIRED OR REPLACED

When any of the following assemblies is replaced

B POWER SUPPLY Unit	No adjustment required
MD DIGITAL Assy	Refer to the "7.1.5 BACKUP WHEN THE MAIN UNIT IS ADJUSTED"
	on ARP3340 (PDP-425CMX).
42 X DRIVE Assy	No adjustment required
42 Y DRIVE Assy	No adjustment required
Service Panel	Refer to the "6.7 METHOD FOR REPLACING THE SERVICE
C	PANEL ASSY" on ARP3340 (PDP-425CMX).
MAIN Assy	Refer to the "ADJUSTMENT"
SUB Assy (Audio, 232C, Sensor, etc.)	No adjustment required
Other assemblies	No adjustment required

When any part in the following assemblies is replaced
