Cautions and Warnings
• View full-motion, high-action video in WIDE or FULL screen after playing a game or showing a still/PC image.
The recommended duration for showing the action video is three times as long as the game or PC image
was on the screen.
• View full-motion video in WIDE or FULL screen after playing content with side, top, or bottom masking (black
bars). Extensive viewing of masked content without this recovery process can cause uneven wear on the
plasma cells.
7.4 Signal Interference or Noise
Signal interference, also referred to as
video noise
or
white noise
, can be caused by many different situations.
The most common are addressed in the following sections.
Infrared rays
The flat panel TV releases infrared rays because of its characteristics. Depending on how the flat panel TV is used,
remote controls for nearby equipment may be adversely affected. Wireless headphones using infrared rays can
experience noise interference. If this is the case, move equipment to a location where its remote control sensor
is not affected.
Radio Signals
While this flat panel TV meets the required specifications, it can affect the signals for surrounding equipment. If
your radio, PC, VCR, or other electrical equipment is disrupted by the panel, move the equipment away from the
panel.
Flat Panel TV Motor
The screen of the flat panel TV is composed of extremely fine pixels that emit light according to received video
signals. This principle may cause you to hear a slight buzz or electrical hum coming from the panel. This is a
normal sound for the flat panel TV and does not indicate a failing unit.
Flat Panel TV Fans
You may hear the sound of a fan motor at times. The slight noise is caused by a cooling fan motor speeding up
when the ambient temperature of the flat panel TV rises. This is a normal function of the panel and is not a
malfunction.
7.5 Phosphor Properties
The following are typical effects and characteristics of a phosphor-based matrix display and as such are not
covered by the Warranty:
• Permanent residual images upon the phosphors of the panel
• Existence of one or more inactive light cells in small quantity
• Noises generated by fan motors, electrical circuits (hum), panel plates, etc.
7.6 Image Information Including Retention & After-Image Lag
Menu Window Size (after a Video Switch)
Programs may be high definition (HD) or standard definition (SD). This flat panel TV automatically scales to the
appropriate definition type. If the video program’s definition type changes while a menu window is on screen (for
example: HD to SD or SD to HD) the menu size may temporarily shrink or enlarge until the panel finishes
adjusting the picture. Adjusting may happen, for example, when switching between a TV program and playback
from a DVR, or when a recorded program switches between different definition types while the menu is showing.
The menu returns to its normal size after a couple of seconds. This action is normal and does not indicate a
problem with your flat panel TV.
Pixel Information
Plasma screens show picture using pixels. Pioneer flat panel TVs contain a very large number of pixels. The size
of the panel determines the number of pixels. With the ELITE Series models, there are over 6.2 million pixels in
the 50”/60” panel. All Pioneer display panels are manufactured using a very high level of ultra-precision
technology and undergo individual quality control.
