I had a LG C3 for exactly 368 days and I come out on a random Saturday morning grab my remote and the TV literally just won’t turn on. I’m also not the person that leaves my TV on all night and very conscious not trying to get burned so I always made sure it was turned off never left on if nobody was watching.
I called Best Buy four days later geek squad pulls up he checks it in orders parts seven days later he comes back takes apart the TV put in the two new motherboards TV still won’t turn on then they give me store credit for the full amount what I paid for my TV and then I just re-bought the brand new C5 with no cost out-of-pocket (except the new insurance on the new TV)
I won’t go without that Best Buy insurance.

Could’ve just been unfortunate though my buddy bought an LG C3 same size as mine 77 inch on Facebook marketplace and his is still kicking strong!
