Hey there! Please feel free to send me a private message with your full model and serial number http://bit.ly/2tCGnGK
Any update on this or the cause? I have the exact same problem. 1/4 the way up from the bottom is a horizontal line that goes all the way across the screen. I have a 2018 Q6FN that I bought in July of last year.
We are sorry to hear about this. Please send the model and serial numbers to this PM Link.

Okay. We will continue the conversation through email.
I too had that problem. Horizontal line just about 1/2 way down about 4 months after purchase...I have the 82" inch Q6. Service came to my house and replaced the led panel/screen no charge in about an hour (still under waranty). Awesome service! Make sure you are as detailed as possible on the initial call so they have the right parts ordered. Like...Power disconnect did not correct. The diagnostic test screens failed. Same issue on all sources etc. Hope this helps!
