The monitor has pixels that are always dark
■
Your plasma TV is manufactured using an extremely high level of precision
technology. However, sometimes some pixels of your plasma TV may not
display. Pixel defects within industry specifications are inherent to this
type of product and do not constitute a defective product.
An image remains on the screen even after you turn off your
plasma TV
■ A still image may have been displayed for an extended period of time
causing burn-in. For more information about burn-in, see page 43.
You see “noise” or “trash” on the screen
■ When your plasma TV’s digital capabilities exceed a digital broadcast
signal, the signal is up-converted (increased) to match your plasma TV’s
display capabilities. Up-converting can cause noise or trash.
Screen brightness is diminished
■ Video display devices experience degradation of brightness over the life of
the device. Normal brightness degradation is not covered by your warranty.
