Respuesta a "Why is my 55 inch LG TV turning off by itself?"Hi I had the same problem with two LG TV`s , tried everything. I did thing of dumping the TV`s and getting different make. Until I changed media sharing. It`s deferentially a network issue I removed the LG TV from my home network media sharing from PC & Laptop, so I blocked media sharing to LG TV and the TV has been perfect since.
