The picture is
distorted.
The compression of video content may cause picture distortions, especially in fast
moving pictures from sports programmes and action movies.
A weak or bad quality signal can cause picture distortions. This is not an issue
with the TV.
Mobile phones used close to the TV (within 1m) may cause noise in analogue and
digital channels.
The colour is wrong or
missing.
If you’re using a Component connection, make sure that the Component cables are
connected to the correct jacks. Incorrect or loose connections may cause colour
problems or a blank screen.
The colour is poor

bright enough.
