NOTES
1
Buzzing sound from Plasma display
panel.
A buzzing sound may be heard when the plasma television is turned on
in a very quiet room. This is due to the plasma panel drive circuit when it
is functioning. The buzzing sound is normal and is not a malfunction.
2
Infrared interference
Some infrared rays are emitted from the plasma television panel that
might affect the operation of other infrared controlling equipment.
3
Bright and dark spots
High precision technology is used to manufacture the plasma television.
But there maybe points that do not illuminate, points that are too bright,
and points with color different from that of the periphery. Please note that
this is not a malfunction.
4
Residual Image
In some cases, residual images may remain after the short term display
of still images when the picture changes.
5
Display panel surface temperature is
too high.
The plasma display panel display images by means of electrical
discharges inside the panel. This may cause the temperature of the
panel surface to increase. Please note that this is not a malfunction.
6
Plasma Surface
A reinforced glass filter is installed over the plasma panel surface. A
strong impact to the front panel risk a danger of glass breakage.
7
Transportation
Please transport the plasma television in it’s packing box and placed in
an upright position. Do not transport the plasma television in a horizontal
position. This increases the posibility of panel breakage and pixel
failure.
8
Granular spots
When a screen is seen at point-blank range, a random fine grain may be
visible in the dark areas of the picture.
9
High temperature environment
High temperature affect the electric discharge/luminescence characteristic
of the PDP panel. Do not place the plasma television in high temperature
environments.
