Trouble Shooting
Before arranging for service, firstly know the status and then check simply as follows:
Problems Check
No picture or sound. Check if the power supply is plugged in.
Check if the power switch is in “on’” position.
Picture is OK, no sound. Check if the volume control is set to the minimum or mute position.
Remote control doesn’t work. Check if the power switch is in “on” position.
Check if the batteries are out of use or not connected well.
Make sure that there is no strong light striking the sensor window of
remote control unit.
Check there are no obstacles between the sensor window and remote
control unit.
No TV signal. Check if the TV/AV button is not set to TV status.
Check if the antenna is well connected.
Check if you installed the TV correctly.
No external video signal. Check if you installed the TV correctly.
Check if the TV/AV button is set to AV position.
Picture lacks colour or picture
too dark.
Check colour, brightness and contrast controls are correctly adjusted.
All channels lose colour
intermittently.
Check if the antenna is broken.
Check if the antenna is disconnected.
Check if the antenna is damaged.
Poor reception, loss of colour
with certain channels.
Check if channels are correctly tuned (see “Fine tuning”).
Diagonal stripes appear on
picture.
The receiver may be affected by interference (e.g. from nearby radio
broadcasting transmitter or from another TV receiver).
Picture has “snow”. Check if the antenna is broken.
Check if the antenna is disconnected.
Check if the antenna is damaged.
Ghost images appear. Check if the antenna direction has been changed by a storm or strong
wind, etc. (because ghost images are caused by the arrival at the
antenna of both the signal which has traveled directly from the
transmitter and the signal which has been reflected from a hill or a large
building. The direction of the antenna should be chosen for minimized
ghosting.)
