Bought a new TV for the living room this weekend, hooked everything up and it was fine. Didn't have the right size screws for the wall mount so the next day I went and got some, unplugged everything, and hung it on the wall. Now the TV can't see my Fire TV Cube. Sees every other device but not the cube. Cube works on every other TV in the house. I ordered a new one that will be here today. Guess if it doesn't work I'll go to Best Buy and see about a replacement for the TV. Maybe I should have listened to the guy at Best Buy trying to convince me to buy a Samsung. But all my Samsungs have been absolute shit so I went with LG again. They've always been great for me up until now.
