Problem Solution
You cannot see a picture. Make sure that the power cord is plugged into a grounded electrical outlet.
Make sure that the power button is turned on.
Make sure that the selected input source is connected to a working input
source.
If your TV is connected to your computer in RGB or HDMI mode, press any
key on your keyboard to “wake” your computer.
You see a distorted picture
or hear unusual sound. You may be getting interference from electrical appliances, cars,
motorcycles, or fluorescent lights. If you have not mounted it on the wall,
try moving your TV to another location to see if this is the cause of the
problem.
The picture has abnormal
patterns. Make sure that the input source cable is attached securely and correctly to
the back of your TV.
Make sure that the video input source is within the range of your TV.
Compare the video input source’s specifications with your TV
specifications.
The display image does
not cover the entire
screen. If you are using RGB mode, make sure that H Size and V Position in the
On Screen Display (OSD) are set correctly.
If you are using TV, AV1, AV2 or Component with 480i input, use the WIDE
button on the remote control to scroll through various screen modes.
You can see a picture but
you cannot hear sound. Make sure that the volume is not turned down.
Make sure that the sound is not muted.
Make sure that your audio input source cables are connected securely and
correctly.
The TV has pixels that are
always dark or colored. Your LCD HDTV is manufactured using an extremely high level of
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. The LCD HDTV is an ideal platform for viewing High Definition Content.
Best Image Quality will be achieved by the HDMI Input, then YPbPr, then
RGB.
However, due to variances in broadcast practices, it is possible some
image distortions can occur.
