5.5 NON-FAILURE INFORMATION

A
[1] INFORMATION ON SYMPTOMS THAT DO NOT CONSTITUTE FAILURE
For PRO-141FD
Symptom
Symptoms concerning the input format and settings
The picture color for an INPUT 4 to 8 signal is not correct.
The audio signal input to the INPUT 5 to 8 is not output.
No HDMI signal is input.
B
The 1080p input signal is not displayed properly or at all,
although the 1080i input signal is displayed properly.
Video signal not displayed
PC signal not displayed
The contour of PC signals is not displayed properly
Miscellaneous
C
The no-signal off function is not activated.
The no-operation off function is not activated.
Power management does not function.
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.
D
On a 2-screen or BANNER PIP display, the specified input
signal is not displayed.
The set value for each PICTURE item has not been stored in
memory.
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.
E
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.

Cause, item to check, information
The color setting for INPUT 4 to 8 is not compatible with that of the output equipment.
Check whether the color setting is YPbPr or RGB.
The audio setting for INPUT 5 to 8 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.
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.)
INPUT 3: Color Decoding is not set correctly for Color Difference signal (1 or 2).
INPUTs 4–8: Signal identification is not correctly set to Video.
INPUT 3: Color Decoding is not set correctly for RGB.
INPUTs 4–8: Signal identification is not correctly set to PC.
Set the signal format properly, according to the resolution of the signal being input.
The no-signal off and no-operation off functions are effective only if video (composite, component,
Dsub, DVI/HDMI [excluding PC]) input or TV input is selected.
Power management is possible only when an analog PC signal, DVI-PC signal, or HDMI-PC
signal is being input. While an input signal other than those is being input, power management is
not available.
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.
Some combinations of input signals are not allowed in 2-screen and BANNER PIP display.
For details on the combination of input signals, see the table below:
Has the INTEGRATOR menu been opened? If it is opened, the values for all PICTURE items
(including Pro Adjust), except for AV SELECTION, become those set on the INTEGRATOR menu.
