• Check that power is available from the power outlet by
trying another known working appliance (e.g. desk lamp)
from that same power outlet.
• Check that the TV is turned on (The power indicator
should be green).

Your TV antenna signal may be effected by interference. Try
redirecting or relocating your antenna to reduce the effects
of the interference. If the antenna is exterior, have a suitable
qualified and experienced antenna specialist adjust the
antenna. Picture ghosting is caused by reflections from
buildings, large metal structures and mountains.
