That’s clearly hardware failure. It will likely get worse. I would check with the manufacturer about the RMA process.

My guess is probably bad driver circuitry in the LCD interface, especially if the lines are always present and don’t move around. Hardware problem—should be replaced without question if in warranty; not economically reparable, IMHO.

Looks like the first generation Gameboy LCD screens. They all developed lines like that after a few years. I think you had to get the screen replaced to fix it.

My big laptop screen has lines just like that (but on the bottom half inch) when it has been out in the cold, but it clears up when it gets warm. My guess is that part of the display is not seeing full voltage (or maybe pulse width) for some reason. If it is because it has been subjected to high humidity at some point, it may eventually heal itself. If it is something defective within the structure of the screen, it probably won't.

Hardware.. probably vid chip (overheat)... did he have it in direct sunlight while using it (or maybe leave it on while exposed to direct sunlight or heat)?
Check the warranty..

Had the same thing happen to a Nexus 6, drove me Batty.

My first LCD widescreen monitor was an NEC. I purchased it about 6 years ago.

After about a year [just after the warranty expired, of course], it developed a black line that extended from one side to the other in the middle of the screen. Soon, another developed near it. And another. And another, until it was a solid black bar nearly 2 inches wide. After the monitor was on a while, at first, the bars would disappear eventually. Then, they stayed on.

I finally replaced it with an AOC 23.5” LCD, which, now, is almost 2 years old, and I have never had a problem with this one.

NEC is on my junk list with Lexmark inkjet printers and Samsung laptops and DVRs.
