I have used the 1) Sennheiser and 2) Sony wireless headphones on my LG 47LA6250 TV by connecting them through the 3.5mm 'HP Out' on the back of the TV. The connection works for up to 5 minutes and dies. To re-establish connection, I have to unplug and plug back. Again, the headphone reception dies after a few minutes. Is there a fix for this?
