Possible cause and solution
It is usually caused by local interference, such as cars, daylight lamps
and hair driers. Adjust the antenna to minimize the interference.
If the antenna is located in the fringe area of a television signal where
the signal is weak, the picture may be marred by dots, show blocking
or break-ups. When the signal is extremely weak, it may be necessary
to install a special antenna to improve the reception.
1. Adjust the position and orientation of the indoor/outdoor antenna.
2. Check the connection of the antenna.
3. Fine tune the channel.
4. Try another channel. Broadcasting failure may happen.
Ghosts are caused by the television signal following two paths. One
is the direct path, the other is reflected from tall buildings, hills, or
other objects. Changing the direction or position of the antenna may
improve the reception.
This interference produces moving ripples or diagonal streaks, and
in some case, loss of contrast in the picture. Find out and remove the
radio interference source.
Read/write speed of your USB device could be too low. Make sure to
use a USB storage device with sufficient speed and space. Pen drives
(USB sticks) may not support sufficient speed.
a) Cables might have loosened; moisture might have entered into
cables or connectors, heavy rain at present or heavy storm at
present. Check the cable connections, LNB and other equipment
connected between the LNB and the receiver, or peak the dish.
Wait for rain/storm to subside. Ask a local satellite specialist for
advice.
b) The satellite dish is not pointing at the (correct) satellite(s). Adjust
the dish. Ask a local satellite specialist for advice.
c) Satellite dish is too small, trees or buildings in path. Change to a
larger dish or change position of dish.
d) Signal is too strong, dish is oversized. Connect a signal attenuator
to the LNB input. Ask a local satellite specialist for advice.
Heavy rain will attenuate satellite signals, below a certain level
blocking will occur.
Make sure your dish installation is up to standards to minimize rain
effects. When in doubt, ask a local satellite specialist for advice.
Again, turn on the TV.
