Troubleshooting

Broadcast reception

Poor reception or poor picture quality with digital broadcasts.

Change the position, direction and angle of the terrestrial television antenna to maximize the antenna signal level. Make

sure that the direction of the antenna 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 and the TV, it may affect the TV

reception. Directly connect the antenna and the TV to check if the reception is improved.
