Question Weird white spots on Philips TV (philips 55pus6101/12)

[Tensdale]

There's a symmetry to them. Does anyone know what's causing this and how I should go about fixing it?

Most likely the back light is defective, eventually you can replace the faulty LEDs by yourself. Or the back light controller on an electronics board is faulty.

That´s why the dots of some back light LEDs are visible in your case

just an example (don´t know if these are compatible to yours), how your back light looks like behind the panel:
