Make sure that your audio input source cables are connected securely and

1 correctly.

The TV has pixels that are
always dark or colored.

Your LCD HDTV is manufactured using an extremely high level of i
precision technology, however, sometimes some pixels of your LCD HDTV

may not display. Pixel defects within industry specifications are inherent to

this type of product and do not constitute a defective product.

You see “noise” or “trash”
on the screen.

When your LCD HDTV’s digital capabilities exceed a digital broadcast
signal, the signal is up-converted (increased) to match your TV’s display
capabilities. Up-converting can cause noise or trash.

You switch to a different

input and the volume
changes.

The TV remembers the volume level from the last time you adjusted it. If
the sound level is higher or lower from another source, then the loudness
will change.

Tips for High-Definition

Users.

1 The LCD HDTV is an ideal platform for viewing High Definition Content.

1 Best Image Quality will be achieved by the HDMI Input, then YPbPr, then

RGB.

1 However, due to variances in broadcast practices, it is possible some

image distortions can occur.
