Which means they can be sued easily in consumer court. My Sony phone's touchscreen buttons would stop working half of the time, and it didn't have physical buttons, rendering the phone unusable. Turned out it was a problem with the model only, and Sony was offering upgrades/replacements abroad, but they refused to do that here. I took them to consumer court, used the forum posts to prove its a fault acknowledged by Sony, and won the case. Sony didn't even contest. Social media wasn't exactly the rage back then. This was 10 years ago. Now the sales they might lose if people complain about burn-in vocally would cost way more than just replacing panels.
If my TV gets burn-in in the next 3 years, I'm getting the panel replaced for sure. It's easy to pressurize the company. Don't care what their warranty says. Plus, considering how easily they agreed to a panel replacement for uniformity, the extreme measures won't even be needed. Wanna bet people said in the uniformity thread that LG might not agree to replacement here?
Just gotta be savvy and not take shit.
