TV Problem

[OpenToeSlipper]

Hi all, I've been having this issue with my Hisense H65m7000 for over a year now, it used to happen once ever few weeks, now happens multiple times a day. I've attached a clip. Usually immediately after this, the screen starts cycling colours with no other display. It's fixed by putting into standby then turning back on.

There's no warranty remaining, any clues what this could be? Any boards I should be looking to swap out? Cheers
