Precautions
On the PDP (Plasma Display Panel) (KE-P42M1 only)
On image
• Please note that the PDP screen is made with high-precision technology. However, black points or bright points of light (red,
blue, or green) may appear constantly on the PDP screen, and irregular coloured stripes or brightness may appear on the PDP
screen. This is not a malfunction.
• With extensive use of this TV set in 4:3 mode, the 4:3 screen area might become darker within a 16:9 panel. To avoid this
problem, the “Smart” picture mode should be used (see page 37).
On image retention
• If the following images are displayed for an extended period time, image retention (afterimage) in areas of the screen may result
due to the characteristics of the Plasma Display Panel.
–Black bars at the top and bottom that appear with a wide video source (Letterbox picture).
–Black bars to the left and right that appear with a 4:3 video source (conventional TV broadcasts).
–Video game sources
–DVD on-screen menu displays
–On-screen menus, channel numbers, etc., of connected equipment such as Set top box, Cable modem, VCR, etc.
The risk of this is higher if the set is in “Live” mode or has a high contrast setting. This image cannot be removed once burnt
onto the screen. To avoid the risk of image retention do not leave the TV set operating on such a picture, or programme for a
long time, use the “Screen Saver” function (page 39) or lower the contrast setting. Repeated extended daily usage of the same
image, or programme can also result in this occurrence. IMAGE RETENTION IS NOT COVERED BY THE SONY
WARRANTY.
• To reduce image retention, this TV set has the “Screen Saver” function. The default setting of the “Orbit” function in “Screen
Saver” is “On” (page 39).
• The “Screen Saver” function prevents and reduces image retention. For more details, see page 39.
On altitude
When used at an altitude of greater than 1900m or 6248 feet (air pressure less than 800hPa), this Plasma Display Panel may generate
a low buzzing sound as a result of the difference between the interior and exterior air pressure of the panels. This is not considered
a defect and is not covered under by the Sony Warranty. This buzzing sound is an inherent characteristic of any Plasma Display
Panel.
