Faint black horizontal lines showing on white screen

I have a 65 inch Vizio M65 C1 tv. When on a white or light colored screen there are these darker horizontal lines starting about half way down the screen, and are about 2 and a half inches apart. From what I can tell they go across the whole screen but are more prominent in the middle. Is this something easy to fix or am I going to need replacement parts or a new tv?

@thyran that actually looks like a backlight issue. For now I would learn to live with it. It could be that it is the LED’s themself or the diffuser sheets (unlikely). If you really, really, really need to fix it you will have to completely disassemble the LCD panel and replace the LED backlight array.
