Solutions❑and❑Explanations
●
It is normal. The TV operates the OTA (Over The Aerial)
function itself to upgrade firmware downloaded whilst
your watching TV.
●
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.
●
Check and change the signal/source.
●
To prevent this, use felt pads on any surface of the TV
that comes in direct contact with furniture.
