TROUBLESHOOTING

Check the TV set is plugged in.
Check the Volume, Brightness, and Contrast controls are not set at minimum.
Check the Volume control is not set at minimum.
Check that the mute function is off.
Check the Brightness and Contrast controls are not set at minimum.
Check the Colour control is not set at minimum.
Check the aerial cable is not broken, disconnected or damaged.
The picture may be affected by an interfering signal. (eg. from nearby
amateur radio transmitters or another TV set). The interference can be
reduced to some extent by adjusting the direction or height of the aerial.
Check the aerial cable is not broken, disconnected or damaged. Small dots
all over the screen are caused by a weak aerial signal.
Check that the aerial direction has not changed after a storm or strong wind
etc...
Ghost images are caused by a signal being reflected from a large building
or a hill : the direction or height of the aerial should be chosen well in order
to minimise the ghosting images.
