Quick answer
On LG TVs with HbbTV turned on, the screen turns green and warns that an application will restart to free memory. LG Spain blames a faulty broadcast: disconnect the aerial cable for 5 minutes and then reset the TV.

What it means
LG Spain describes this issue on sets with HbbTV enabled, the interactive service that arrives with the terrestrial signal: the screen shows a green colour and a message warning that an application will restart to free memory (wording translated from LG Spain). LG gives a faulty broadcast as the cause, meaning data arriving through the aerial, not a TV fault. Its steps are to cut the aerial signal, reset, update the software and, if it continues, notify the Call Center.
