1. CONTRAST OF MISCELLANEOUS PARTS

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.
Screws adjacent to mark on product are used for disassembly.
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.)
Nos. indicate the pages and Nos. in the service manual for the base model.
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%).

B

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

Notes when visiting for service

1. Notes when disassembling/reassembling

1 Rear case

When reassembling the rear case, the screws must be tightened in a
specific order. Be careful not to tighten them in the wrong order forcibly.
For details, see "Rear Case" in "7. DISASSEMBLY".

2 Attaching screws for the HDMI connector

When attaching the HDMI connector after replacing the Main Assy,
secure the HDMI connector manually with a screwdriver, but not
with an electric screwdriver. If you tighten the screws too tightly
with an electric screwdriver, the screw heads may be damaged, in

B

which case the screws cannot be untightened/tightened any more.

2. On parts replacement

1 How to discharge before replacing the Assys

A charge of significant voltage remains in the Plasma Panel even
after the power is turned off. Safely discharge the panel before
replacement of parts, in either manner indicated below:

Let the panel sit at least for 3 minutes after the power is turned off.

4.4 NON-FAILURE INFORMATION

4.4.1 INFORMATION ON SYMPTOMS THAT DO NOT CONSTITUTE FAILURE

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 3 or 4 or 5 signal is not
correct.

The video signal to INPUT 3 or 4 or 5 is not displayed, and a
message is displayed.

The audio signal input to the INPUT 3 is not output.
No HDMI signal is input.

The color setting for INPUT 3 or 4 or 5 is not compatible with that of the output equipment.
Check whether the color setting is YPbPr or RGB.

A unsupported video signal is input.

The audio setting for INPUT 3 is any setting and a video signal is not input. If the audio setting is
any setting to output an analog audio signal, the HDMI signal must be input. (If a DVI device is to
be connected, use a DVI-HDMI conversion cable.) If the HDMI video signal is not input, the
analog audio signal is not output.

A

No sound of signals to INPUT 3 or 4 or 5 is output.

The 1080p input signal is not displayed properly or at all,
although the 1080i input signal is displayed properly.

MONITOR video output

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

The video signal is not output when the component signal is
input to INPUT 1 or 2.

The video signal is not output when the video signal is input
to INPUT 3 or 4 or 5.

MONITOR audio output

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

DIGITAL OUT (PDP-508XDA only)

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

The digital audio 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-operation off function is not activated.

Power management does not function.

The AUTO SETUP function is not activated.

The audio signal from the PC is not output.

Control via the SR connector is not possible. Wrong connection of the cable to the PC INPUT (AUDIO) connector is suspected.

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

The picture size changes arbitrary.

The display position of the screen changes slightly while the
screen is on.

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

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

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

Check that the connected cable supports HDMI Category 2. (As the clock frequency for the 1080p
signal is triple that for the 1080i signal, signal degradation caused by a cable must not be
neglected. A cable supporting HDMI Category 2 can be used for the 1080p signal. Although some
conventional cables can support the 1080p signal, some others cannot.)

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

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

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

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

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.

The no-signal off and no-operation off functions are effective only if video (composite, S video,
component, HDMI [excluding PC]) inpu

Power Management is effective only while an analog PC signal is being input. It is not effective
with HDMI-PC signal input.

The Auto Setup function is effective only while an analog PC signal is being input. This function
does not work if an analog PC signal is not input, even if the INPUT PC is selected.

Wrong connection of the cable to the SR 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 Auto Size setting is set to ON.

The orbiter function for minimizing the effects of phosphor burn is activated. Although the setting
for this function can be changed on the Home menu, retaining the factory setting is strongly
recommended.

The component video cable is connected to the same input function as for the S video (even if no
signal is input to the component video connector, merely having something plugged in to the
connector will result in j

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.)
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
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 color-difference
signals. In general, it is said that picture quality for color difference 4:2:2 format is assumed to b
than to colors. In the case of RGB4:4:4, R, G, and B use 8 bits each.
