Poor reception or poor picture quality with digital
broadcasts.
Change the position, direction and angle of the terrestrial television antenna (aerial) to
maximise the antenna (aerial) signal level. Make sure that the direction of the antenna
(aerial) is not changed unintentionally (such as by wind).
If you are using a TV signal booster, adjust its signal gain.
If equipment (such as a TV signal distributor) is connected between the antenna (aerial)
and the TV, it may affect the TV reception. Directly connect the antenna (aerial) and the
TV to check if the reception is improved.
Poor weather conditions can affect satellite broadcast systems. Wait for the weather to
clear. (Satellite compatible models only)
