I bought one in Gome last month. Wireless connection is very slow, sometimes it takes several times to connect. Besides, there is another problem with my TV. After watching cable TV for more than half an hour, Xue Huadian appeared. Haier's after-sales service staff came to see it, saying it was a problem with interference signals, not TV. Other people's cable TV has never had this problem. Why did I encounter such a problem? It's so depressing Is the anti-interference ability of TV poor, or is there really a signal? One more question. The side of the TV with the switch is very hot. After reading it for half an hour, I felt a little hot when I touched the screw with my hand, and the other side was slightly hot. Isn't LED TV very hot? Why is it so hot? The Samsung LED monitor I bought has no cooling holes behind it, so I can't feel the heat for several hours. I don't know if I bought parallel goods. Watching 3D on TV, watching movies on USB flash drive, and watching series online are all very good!
