5.5 NON-FAILURE INFORMATION

[1] INFORMATION ON SYMPTOMS THAT DO NOT CONSTITUTE FAILURE
A
Symptom
HDMI: Symptoms concerning the input format and settings
The picture color for an INPUT 1 or 3 to 5 signal is not correct. The color setting for INPUT 1 or 3 to 5 is not compatible with that of the output equipment.
The video signal to INPUT 1 or 3 to 5 is not displayed, and a
message is displayed.
The audio signal input to the INPUT 1 or 3 is not output.
No HDMI signal is input.
No sound of signals to INPUT 1 or 3 to 5 is output.
B
The 1080p input signal is not displayed properly or at all,
although the 1080i input signal is displayed properly.
SCART video output
The video output signal from the SCART connector is
deteriorated. Or when the video output signal from the SCART
connector is recorded, its playback picture is deteriorated.
The video signal is not output when the component signal is
input to INPUT 2.
The video signal is not output when the video signal is input
to INPUT 1 or 3 to 5.
C
AUDIO OUT and SCART
The image displayed on the PDP is not synchronized with the
sound from the SCART.
DIGITAL OUT
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 SCART video output.
Miscellaneous
The no-signal off function is not activated.
The no-operation off function is not activated.
D
Power management does not function.
The AUTO SETUP function is not activated.
Control via the SR connector is not possible.
The audio signal from the PC is not output.
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.
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.)
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 color-difference
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.

Cause, item to check, information
Check whether the color setting is YPbPr or RGB.
A unsupported video signal is input.
The audio setting for INPUT 1 or 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.
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 SCART connector is Macrovision protected.
The video signal is not output from the SCART connector when the component signal is selected.
The video signal is not output from the SCART connector when the HDMI signal is selected.
The audio signal from the SCART connector is synchronized with the video output signal from the SCART connector.
And the audio signal from the AUDIO OUT is synchronized with the video signal that is currently displayed.
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 SCART video output.
The no-signal off and no-operation off functions are effective only if video (composite, S video,
component, HDMI [excluding PC]) input or TV input is selected.
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 PC INPUT (AUDIO) connector is suspected.
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.
As the signal input to the connector that has been selected on the INPUT SELECT submenu of the Home menu is
selected (this does not apply to the connectors located on the side of the unit), check the menu setting. If the output signal
is not available even if the input signal is properly selected, input a signal to other input functions, check the connecting
cables, or check the settings for the connected equipment. Note that if cables are connected to both the HDMI connector
and composite video connector of INPUT 5, the HDMI connector will have priority over the composite video connector.
