Can't see your video, it's marked as private?
It could be a panel fault - some of these big Sharp panels seem to be having issues with the LCD panels. If so it would not be repairable unfortunately.

Not an easy one...

The backlight looks to be working OK as the bright black glow is still normal during the flickering (if it was there'd be a rare chance of some kind of "frame-synced" flickering causing the lines, but that doesn't look to be the case in this instance.)

Have you taken the back cover off the TV yet? I'm suspecting the panel TBH... that's not great news, but there's a quick test that should rule it in or out. Could be an LVDS cable fault too.
