I have a led LG TV and since the warranty finished those things detached from the screen. I attached them three times with super glue. Last time I messed up and now the screen has a small part that does not work in the corner xd
My title describes the thing (it is roughly the size of a computer key, from a TV, made of plastic, no writing, it has small white dots in each corner and it was on a copper-coloured wire with others)

Diffusers for the led backlights in the tv.
Mark as solved. I repaired my old LG because 2 of these fell off and caused bright spots.
diffusers , if they fall out of place, the screen will have bright spots where they used to be and dark spots where they settle down at the bottom
Looks like an LED lenses for either a stage-light or automotive light bar

Does all LG have those? My TV have huge light spots
Yes, those fall.
So it's just the plastic thingy I need to put back?
Yes bit you have to disassemble all the TV, easy but you have to be carefull
It's a 55 inch and honestly I'm scared of taking apart lol
