Before we explore more complex tv troubleshooting techniques, we
need to examine the basics. First, we need to verify the TV is securely plugged
into a power outlet. Don't laugh, but failure to plug-in the TV is the number
one reason reported why electronics do not work. Second, you need to verify the
remote has fresh batteries. This can easily be overlooked. The remote can be
working one minute and not working the next, so replace the
batteries Finally, verify that all cables and connections are correctly
and securely attached.
Rear-Projection TVs have a
lamp, which picks up the picture and projects it on the TV screen. A burned-out
or connected lamps are two of the most common problems for Rear-Projection TVs.
First, you will want to confirm the bulb is still good. If the bulb is bad then
then replace it immediately. Second consult your user manual and verify the
lamp and lamp cover are installed properly. Most Rear-Projection TVs have
warning light which notify you when there are lamp problems. Again consult the
user's manual to see what each light means.
Temperature is a common
reason why many Rear-projection TVs do not perform well when they get to hot.
You may start to see your TV shutting down automatically when it overheats.
Here are a couple of things you can do to prevent overheating. First make
certain any TV ventilation ports are free and clear of debris and dust. Second
make sure the TV has enough room for airflow. Third, the temperature in
the room should be around 72 degrees. Due to the high degree of heat generated
by a rear-projection TVs, it is not advisable to watch TV on a hot days when
you don't run the air condition. This could cause damage to your TV.
Improperly configuring TV setting can cause
problems. Verify the TV settings are set correctly. First, brightness and
contrast should not be set to high or to low because this can cause poor
picture images. Second, adjust the color on the TV when the picture displays
colors poorly. Third, if you are having sound issues then check to make sure
the volume is not muted or turn down all the way.
