5.5 NON-FAILURE INFORMATION
5.5.1 INFORMATION ON SYMPTOMS THAT DO NOT CONSTITUTE FAILURE
Information on symptoms that do not constitute failure
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 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.

HDMI: Symptoms concerning the input format and settings
The picture color for an INPUT 4 to 7 signal is not correct.
The color setting for INPUT 4 to 7 is not compatible with that of the output equipment.
Check whether the color setting is YPbPr or RGB.
The video signal to INPUT 4 to 7 is not displayed, and a
message is displayed.
A unsupported video signal is input.
The audio signal input to the INPUT 4 to 5 is not output.
No HDMI signal is input.
The audio setting for INPUT 4 to 5 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.
No sound of signals to INPUT 4 to 7 is output.
The setting on the side of the HDMI output equipment is wrong.
Example: Dolby Digital
DIGITAL OUT
Playback of the signal from the DIGITAL audio output
connector is possible, but recording is not possible.
The video signal output from the DIGITAL connector is copy-protected.
Miscellaneous
The no-signal off function is not activated.
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.
The no-operation off function is not activated.
Power management does not function.
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 not activated.
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.
Control via the SR connector is not possible.
Wrong connection of the cable to the PC INPUT (AUDIO) connector is suspected.
The audio signal from the PC is not output.
Wrong connection of the cable to the SR connector is suspected.
The picture-quality setting (AV Selection) is not stored.
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 picture size changes arbitrary.
The Auto Size setting is set to ON.
The display position of the screen changes slightly while the
screen is 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 1080p input signal is not displayed properly or at all,
although the 1080i input signal is displayed properly.
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 to the S video connector is not displayed.
The S Video or component video cable is connected to the same input function as for the
composite video. (Priority of connectors: component video > S video > composite video)
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 judgment that a signal is being fed in and the component video connector
takes priority). (Priority of connectors: component video > S video > composite video)
The video signal to the composite video connector is not
displayed.
