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.
Health & Safety Code Section 25249.6 ­ Proposition 65
NOTICE
(FOR CANADIAN MODEL ONLY)
Fuse symbols
(fast operating fuse) and/or
(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
NOTICE : 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 while handling.
2. When service is required, even though the HDTV PROJECTION
MONITOR 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 manufacture's replacement components.
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 service
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
manufacture has become defective, 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 the 120V AC 60Hz 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 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.

SD-533HD5, SD-643HD5
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 measured must not exceed 0.5mA.
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 indicating
that voltage has increased in excess of a predetermined 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 be operated.
Serviceman Warning
In the status of the black picture (video muting is being applied)
when no signal is input, high voltage of this set during operation is
less than 30.5kV. In case any component having 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 connector. (Refer
to section "7.1.2 DISASSEMBLY".)
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 (CRT Service Assy R, G, B) used 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 Service 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 Service Assy R, G, B) itself.
Moreover, when the voltage of the high voltage circuit becomes
abnormally a little higher, the picture tube radiates X-rays.
Accordingly, when servicing the high voltage circuit be sure to
replace as an assy with the POWER SUPPLY 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. Replacement 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 dose 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 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.

1.3 CHARGED SECTION, HIGH VOLTAGE GENERATING POINT AND X-RAY
PROTECTION
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 damaged 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.

X-ray protection
· Regarding the parts which are relative to radiation of X-rays (There
is the danger to radiate X-ray from the individual CRT Service
Assy R, G, B), there are notifications of caution 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 Service 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 Service Assy R,
G, B. Accordingly, never supply current only to the CRT Service
Assy R, G, B.
Moreover, the anode voltage of the CRT Service 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 Service Assy R, G,
B by using a completely functional Deflection Service Assy
(including FBT) which have been adjusted completely in the
combined state. (When the voltage abnormally becomes high, the
X-ray protection circuit will operate.)
