I bought a QN65Q8FNB in March 2019. It has worked flawlessly until tonight. While watching TV, a horizontal line appeared on the TV, stretching from the left frame to the right. Then, 10 minutes later, a vertical line appeared, from the top to the bottom of the frame. These lines appear on every input. They were also there during the picture test. The screen has never been hit or mishandled in any way. I would appreciate any advice on how to get this fixed. Thanks.
Can you send me a private message with your full serial number and pictures of the symptoms you're experiencing? http://bit.ly/2tCGnGK
