Replacing the TCON/LCD Controller board fixed the issue.
I've got a TV with the same issue as this one:

Ive got another TV of the same type which I can source parts from so Im just trying to figure out what is causing the issue. Ive already replaced the board that has all the inputs on it to no avail.
Thanks
