Solutions and Explanations
•
This is part of the product's design and is not a defect.
•
PIP functionality is only available when you are using a HDMI, PC or
components source.
•
If you are using a CAM CARD (CI / CI+), check that it is installed into the
common interface slot.
•
If there is still a problem, pull the CAM CARD out of the TV and insert it
into the slot again.
•
It is normal. The TV operates the OTA (Over The Aerial) function itself to
upgrade firmware downloaded whilst your watching TV.
