One end of screen “pulses” on white screen Can't Post

Tv: LG 47LN5750 LCD
Issue: when in a white screen, the left side pulses 2 seconds bright white, 2 seconds darker white. When it is bright, that’s normal and matches the right side. The darkness isn’t uniform, it’s a gradient with the darkest being on the left edge, and the centre of the TV being normal.

I’ve already replaced the backlight (some LEDs were burnt out), and I’ve checked that it isn’t pulsing. It’s the actual pixels changing. It isn’t as obvious with a video playing, but it’s still noticeable.

Here is a video on what’s happening: https://youtu.be/GrW_0SIJzHw

Anyone have any ideas on what’s wrong and how to fix it?
