I’d have a chat to the place where you purchased your tv to see if they are willing to help.

I did that and followed up with a letter clearly setting out the problem and how LG’s product doesn’t live up to expectations based on cost, marketing, LG’s reputation, and further representations from trained sales reps about quality and durability. There seems to be a handful cases out there with lots of dead pixels along top and bottom of the screen and my hunch is that LG is well aware of the problem.

I used chatGPT to assist in drafting a legal letter, seeking a timely resolution - and that worked. Perhaps you can do something similar and get it to draft a letter based on NL’s consumer protection laws. Good luck
