Sorting through the bits that came with our TV, there's a 'ferrite core' that according to the manual should be clipped around the mains cable where it goes into the TV. The installer didn't clip it on, should I? I had a bit of a look on the internet but couldn't really find an explanation of what it does or the pros/cons of fitting it.

There shouldn't be any drawbacks of fitting the core. You may or may not notice a difference when you attach it. The core is used to try and stop RFI (radio frequency interference) from getting-into or radiating-out-of the mains cable (more the latter). Stick it on and as long as it doesn't make anything obviously worse, leave it there.
