1. SAFETY INFORMATION

This service manual is intended for qualified service technicians; it is not meant for the casual do-it-

yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to

properly and safely repair complex products such as those covered by this manual.

Improperly performed repairs can adversely affect the safety and reliability of the product and may void the

warranty. If you are not qualified to perform the repair of this product properly and safely, you should not

risk trying to do so and refer the repair to a qualified service technician.

WARNING

This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of

California to cause cancer, birth defects or other reproductive harm.

(slow operating fuse) on PCB indicate that replacement parts must

be of identical designation.

REMARQUE

(POUR MODÈLE CANADIEN SEULEMENT)

Les symboles de fusible

(fusible de type rapide) et/ou

(fusible de type lent) sur CCI indiquent que les pièces de

remplacement doivent avoir la même désignation.

1.1 SAFETY PRECAUTIONS

NOTlCE: Comply with all cautions and safety related notes

located on or inside the cabinet and on the chassis or picture

tube.

The following precautions should be observed:

1. Do not install, remove, or handle the picture tube in any

manner unless shatterproof goggles are worn. People

not so equipped should be kept away while picture tubes

are handled.

Keep picture tube away from the body while handling.

2. When service is required, even though the PROJEC-

TION MONITOR RECEIVER an isolation transformer

should be inserted between power line and the set in

safety before any service is performed.

3. When replacing a chassis in the set, all the protective

devices must be put back in place, such as barriers,

nonmetallic knobs, adjustment and compartment

covershields, isolation resistor-capacitor, etc.

4. When service is required, observe the original lead

dress.

Extra precaution should be taken to assure correct lead

dress in the high voltage circuitry area.

5. Always use the manufacturer's replacement compo-

nents. Especially critical components as indicated on the

circuit diagram should not be replaced by other

manufacture's.

Furthermore where a short circuit has occurred, replace

those components that indicate evidence of overheating.

6. Before returning a serviced set to the customer, the ser-

vice technician must thoroughly test the unit to be certain

that it is completely safe to operate without danger of

electrical shock, and be sure that no protective device

built into the set by the manufacturer has become defec-

tive, or inadvertently defeated during servicing.

Therefore, the following checks should be performed for the

continued protection of the customer and service technician.

Leakage Current Cold Check

With the AC plug removed from 120V AC 60Hz source,

place a jumper across the two plug prongs. Turn the AC

power switch on. Using an insulation tester (DC 500V), con-

nect 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.), particu-

larly 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 0.3M

and a maximum resistor reading of 5M

. Any resistor value

below or above this range indicates an abnormality which

requires corrective action. Exposed metal parts not having a

return path to the chassis will indicate an open circuit.

PRO-700HD

Leakage Current Hot Check

Plug the AC line cord directly into a 120V AC 60Hz outlet (

do not use an isolation transformer for this check). Turn the

AC power switch on.

Using a "Leakage Current Tester (Simpson Model 229

equivalent )", measure for current from all exposed metal

parts of 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 mea-

sured must not exceed 0.5mA.

X-radiation

TUBE: The primary source of X-radiation in this set is the

picture tube.

For continued X-radiation protection, the replacement tube

must be the same type as the original, PIONEER approved

type.

The picture tube (the CRT assy R, G, B ) use in this set

holds complete guarantee against X-ray radiation when the

X-ray is sealed (See page 4). Accordingly, when the current

in flowing to the picture tube (CRT assy R, G, B) be sure to

perform it by putting the tube into X-ray sealed applied state.

Avoid absolutely to flow the current to the picture tube (CRT

assy R, G, B) itself. Moreover, when the voltage of the high

voltage circuit becomes abnormally a little higher, the pic-

ture tube radiates X-rays. Accordingly, when servicing the

high voltage circuit be sure to replace as an assembly with

the DEFLECTION SERVICE assy in the manner in which

has been adjusted to perform normal operation.

1.2 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. Replace-

ment parts which have these special safety characteristics

are identified in this Service Manual.

Electrical components having such features are identified

by marking with a

on the schematics and on the parts list

in this Service Manual.

The use of a substitute replacement component which does

not have the same safety characteristics as the PIONEER

recommended replacement one, shown in the parts list in

this Service Manual, may create shock, fire, X-radiation, or

other hazards.

Product Safety is continuously under review and new in-

structions are issued from time to time. For the latest infor-

mation, 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.

ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED

ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD

AND MUST BE CORRECTED BEFORE RETURNING THE SET

TO THE CUSTOMER.

High Voltage

This set is provided with a X-ray protection for clearly indi-

cating that voltage has increased in excess of a predeter-

mined value. Comply with all notes described in this Service

Manual regarding this hold down circuit when servicing, so

that this X-ray protection may correctly by operated.

Serviceman Warning

In the status of the black picture ( video muting is being ap-

plied ) when no signal is input, high voltage of this set during

operation is less than 30.5kV. In case any component hav-

ing some relation to the high voltage is replaced, confirm

that the high voltage is lower than 30.5kV in the status of the

black picture when no signal is input.

To measure H.V. use a high impedance H.V. meter.

Connect ( ) to earth and ( + ) to the FBT anode cable con-

nector.

1.3 CHARGED SECTION, HIGH VOLTAGE GENERATING POINT

AND X-RAY PROTECTION

7 Charged section

The circuit in which the commercial AC power is used as it

is without passing through the power supply transformer. If

the charged section is touched, there is a risk of electric

shock. In addition, the measuring equipment can be dam-

aged if it is connected to the GND of the charged section

and the GND of the non-charged section while connecting

the set directly to the commercial AC power supply. In this

case, be sure to connect the set via an insulated transformer

and supply the current.

7 X-ray protection

· Regarding the parts which are relative to radiation of X-

rays (There is the danger to radiate X-ray from the indi-

vidual CRT assy R, G, B), there are notifications of cau-

tion in the individual schematic diagrams. Be sure to read

them for safety's sake.

· The component parts for X-ray protection are as follows :

When the current flows to the CRT assy R, G, B, be sure

to perform it with these parts being attached. Protection

from the X-ray radiation is maintained in the state in which

these parts have been installed to the CRT assy. R, G, B.

Accordingly, never supply current only to the CRT assy R,

G, B.

Moreover, the anode voltage of the CRT assy R, G, B

should always be kept not higher than the predetermined

value (in the minimum brightness and picture state when

non signal input is less than 30.5kV). Be sure to drive the

CRT assy R, G, B by using a completely functional DE-

FLECTION assy which have been adjusted completely in

the combined state. (When the voltage abnormally be-

comes high, the X-ray protection circuit will operate.)
