LG model 47LN578V approx 18 months - 2 years old
the kids were playing minecraft on the xbox when it happened and the sounds on that could still be heard. It happened earlier this morning also to my husband but he turned it off and on and it came back fine. Connected is the sky box and xbox at the moment
i unplugged all the cables and put just the sky one in, turned tv back on and the LG logo flicked up on the screen then it just stayed black again.
i have changed the cables for a spare scart lead from tv to sky and i have all the sound just still no picture. the tv is receiving from the remote as i can adjust the volume
