A

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

B

cause cancer, birth defects or other reproductive harm.

NOTICE
(FOR CANADIAN MODEL ONLY)

SAFETY PRECAUTIONS

NOTICE : Comply with all cautions and safety related notes

located on or inside the cabinet and on the chassis.

The following precautions should be observed :

1. When service is required, even though the PDP UNIT an
isolation transformer should be inserted between the power line

D

and the set in safety before any service is performed.

2. 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 resistor­capacitor, etc.

3. 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.

4. 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

E

components that indicate evidence of overheating.

5. 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
servicetechnician.

6. Perform the following precautions against unwanted radiation
and rise in internal temperature.

• Always return the internal wiring to the original styling.

• Attach parts (Gascket, Ferrite Core, Ground, Rear Cover,
Shield Case etc.) surely after disassembly.

7. Perform the following precautions for the PDP panel.

• When the front case is removed, make sure nothing hits the
panel face, panel corner, and panel edge (so that the glass does
not break).

• Make sure that the panel vent does not break. (Check that the
cover is attached.)

• Handle the FPC connected to the panel carefully.
Twisting or pulling the FPC when connecting it to the
connector will cause it to peel off from the panel.

8. Pay attention to the following.

• Pay extreme caution when the front case and rear panel are
removed because this may cause a high risk of disturbance to
TVs and radios in the surrounding.

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 0.3MΩ
and a maximum resistor reading of 5MΩ. 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.

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.
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.

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 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.

NOTES:

A

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.
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%).

How to identify the cause of a power-down that is indicated by 2-times flashing
of the red LED

The cause of a power-down that is indicated by 2-times flashing of the red LED can be identified by performing the steps 1 to
3 below:
1 Visual check with the power off
2 Tester check with the power off
3 Check with the power on

1 Status check with the power off

Check if the cables and FFC cables that are connected to the Y DRIVE Assy are firmly connected.

B

2 Tester check with the power off

1. Check between Vsus and SUSGND with a tester

Disconnect all cables from the X and Y DRIVE Assys and check if there is short-circuiting between Vsus and SUSGND
in the X and Y DRIVE Assys.

• How to check if there is short-circuiting on the X DRIVE Assy:
If there is short-circuiting between Vsus and SUS OUT, and SUS OUT and SUSGND, the X Mask Module is damaged.
If they are not short-circuited, check other elements to see if they are short-circuited.

C

D

• How to check if there is short-circuiting on the Y DRIVE Assy:
If there is short-circuiting between Vsus and SUS OUT, and SUS OUT and SUSGND, the Y Mask Module is damaged.
If they are not short-circuited, check other elements to see if they are short-circuited.

• Check for short-circuiting in the Power supply.

Note that at the beginning of measuring with a tester, charging of an electrolytic capacitor may cause a phenomenon
like short-circuiting. However, the resistance will soon rise if there is no short-circuiting.

2. Check for short-circuiting between VH and PSUS with a tester

Disconnect the cables that connect the bridge connectors between the Y DRIVE Assy and upper and lower SCAN
Assys.

• If there is short-circuiting in the upper SCAN Assy, one of Scan ICs in the upper SCAN Assy is damaged.

• If there is short-circuiting in the lower SCAN Assy, one of Scan ICs in the lower SCAN Assy is damaged.

• If there is short-circuiting in the Y DRIVE Assy, a circuit in the Y DRIVE Assy is short-circuited.

If no short-circuiting is detected up to this stage, the power-down in question is proved not to be caused by short­circuiting. Therefore, it is assumed that the power-down occurred because power had not been supplied to Vsus or
VH for some reason.

3 Check immediately after the unit is turned on before a power-down occurs.

If the Vsus voltage does not increase, the POWER SUPPLY Unit is in failure.

E

If the VH voltage does not increase, the VH DC/DC converter in the Y DRIVE Assy is in failure.

4 Check the PD detection circuit.

If no problem is detected in steps 1 to 3, a power-down occurred even though the voltage was normal.
Therefore, the PD detection circuit may be in failure.

By following the above procedures, the real cause of a power-down can be judged.

5.4 INFORMATION ON SYMPTOMS THAT DO NOT CONSTITUTE FAILURE

A

Information on symptoms that do not constitute failure

Symptom Cause, item to check, information

HDMI: Symptoms concerning the input format and settings

The picture color for an INPUT 5 or 6 signal is not correct.

The video signal to INPUT 5 or 6 is not displayed, and a
message is displayed.

The audio signal input to the INPUT 5 or 6 pin jack is not
output.

B

No sound of signals to INPUT 5 or 6 is output.

MONITOR video output

The video output signal from the MONITOR connector is
deteriorated. Or when the video output signal from the MONITOR
connector is recorded, its playback picture is deteriorated.

The video signal is not output when the component signal is
input to INPUT 2, 3, or 4.

The video signal is not output when the video signal is input
to INPUT 5 or 6.

MONITOR audio output

C

The image displayed on the PDP is not synchronized with the
sound from the MONITOR audio output.

DIGITAL audio output

Playback of the signal from the DIGITAL audio output
connector is possible, but recording is not possible.

The video output signal from the DIGITAL connector is not
synchronized with that from the MONITOR video output.

Miscellaneous

The no-signal off function is not activated. The no-signal off function is effective only while a video signal is being input.
The no-operation off function is not activated. The no-operation off function is effective only while a video signal is being input.
Power management does not function. Power management is effective only while a signal is being input from a PC.

D

The AUTO SETUP function is not activated. The AUTO SETUP function is effective only while a signal is being input from a PC.
The G-Link system is not activated. Wrong connection of the cable to the SR connector or PC audio connector is suspected.
Control via the SR connector is not possible.
The audio signal from the PC is not output. A failure in the G-Link system or wrong connection of the cable to the SR connector is suspected.

The picture-quality setting (AV Selection) is not stored.

The picture size changes arbitrary. The Auto Size setting is set to ON (default is OFF).

The display position of the screen slightly changes every time
the unit is turned on.

E

The video signal to the S video connector is not displayed.

The video signal to the composite video connector is not
displayed.

SUPPLEMENT: On the video setting for HDMI

There are three types of HDMI output formats: color difference 4:4:4, color difference 4:2:2, and RGB4:4:4.
(The proportions, such as 4:4:4 and 4:2:2, represent those of the amount of data for video signal components. For example, as for color difference 4:4:4, the
proportion of the amount of data as for Y, Cb, and Cr is 4:4:4.)

The color setting for INPUT 5 or 6 is not compatible with that of the output equipment.
Check whether the color setting is YPbPr or RGB.

A unsupported video signal is input.
Example: 1080p @ 60Hz

The audio setting for INPUT 5 or 6 is "AUTO," and a video signal is not input. If the audio setting
is "AUTO," to output an analog audio signal, the DVI signal must be input via a DVI-HDMI
conversion cable.
When the DVI equipment is connected, the analog signals are selected with the setting "AUTO."

The setting on the side of the HDMI output equipment is wrong.
Example: Dolby Digital

The video signal output from the MONITOR connector is Macrovision protected.

The video signal is not output from the MONITOR connector when the component signal is
selected.

The video signal is not output from the MONITOR connector when the HDMI signal is selected.

The audio signal from the MONITOR connector is synchronized with the video output signal from
the MONITOR connector.

The video signal output from the DIGITAL connector is copy-protected.

The digital audio output signal from the DIGITAL connector is synchronized with the video signal
that is currently displayed, and not with the MONITOR video output.

A failure in the G-Link system or wrong connection of the cable to the PC audio connector is suspected.

The picture-quality setting is stored for each input. As the setting is changed when another input
is selected, the user may have a false idea that the setting is not stored.

The orbiter function for minimizing the effects of phosphor burn is activated. As ON/OFF of this
function can only be changed on the Integrator menu, turning off of this function by a user is not
possible.

Although S video input is selected on the menu, the cable is connected via a component video
input connector whose function type is the same as S video input.

Although the composite video input is selected on the menu, the cable is connected via a
component video connector or S video connector whose function type is the same as the
composite video input.

It is required to make the settings of the PDP according to the settings of the output equipment. For usual operation, however, set them to AUTO. If the color is
inappropriate, make the settings manually.
In the HDMI system, video signals are coded at 24 bits per pixel and transmitted as a series of 24-bit pixels. In a case of color difference 4:4:4, Y, Cb, and Cr use
8 bits each. In a case of color difference 4:2:2, Y, Cb, and Cr use 12 bits each, but Cb and Cr are transmitted at a half sampling rate of Y. This unit is capable of

F

processing the upper 10 bits out of 12 bits of video data. Recent high-end DVD players, such as Pioneer DV-79AVi, are capable of outputting 10-bit color­difference signals. In general, it is said that picture quality for color difference 4:2:2 format is assumed to be higher, because human eyes are more sensitive to
luminance than to colors. In the case of RGB4:4:4, R, G, and B use 8 bits each.
