TROUBLESHOOTING TIPS
Check that the antenna / cable is connected properly and that you have selected the correct
source type (refer to page 11).
There could be temporarily no transmission on the selected channel. When transmission is
resumed or when available, your TV will receive it.
The current channel has only audio transmission.
This could be due to any of the following reasons:
1. Not all transmitted broadcasts by the cable or broadcast stations are in STEREO. Try checking
with several major network stations to be sure that the station you selected is in STEREO.
2. When using an AV input, the television will not display STEREO even though it is producing
stereo sound.
It is normal to hear a disturbing sound (such as buzzing, clicking, cracking, humming, whistling, etc)
from a distance less than 2 meters (6 feet) with the television sound muted.
If problem occurs on one channel, you may have a signal problem. Please contact the cable provider
or local broadcaster regarding the specific channel.
Check the TV power cord. Unplug the power cord from the TV, wait 10 seconds, then reinsert
the plug into your wall outlet. Power On the TV again.
Plug the power cord directly to the wall socket and not via an extension cord.
If you need to use an extension cord, check that the fuse on the AC power strip is not blown.
Ensure the batteries are inserted into the remote control according to the illustration in the
battery compartment (refer to page 7).
Reset the TV by disconnecting the power plug from the wall outlet for 10 seconds and then
reconnecting it again.
Check antenna connections. Are they properly secured to the TV ANT 75 ohm plug?
Check the SOURCE TYPE control for the correct tuner setting.
Try running the Auto Channel Search feature to find all available channels (refer to page 9).
Press the SOURCE button on the remote control to make sure the correct signal source is
selected (FRONT, AV1, CVI, Current Channel, etc.).
Some DVD discs are encoded with as much as 30% more video information to give the best
possible picture quality. With the DVD player in the 16:9 picture format, the playback of this
type of disc with extra video information can produce a number of small white lines in the
upper portion of the black letterbox area. With some of these discs, this problem is inherent
and does not require a service call.
