Component failures happen. I had a Phillips 4K LED TV I purchased on sale in April 2021. The TV was glitchy, and I'd get all sorts of weird problems with it - but nothing really terrible. Then two weeks into January this year, the picture suddenly becomes a jumbled mess of vertical stripes. One second it's fine, the next second it's broken. Luckily we have a general 5 year warranty period here in Norway, and TVs are expected to last for at least 5 years. I called the shop, and they told me to just bring the TV. When I get there with the TV, I notice two other identical TVs. I check out the note that hangs on them, and see that they are broken, with the same symptoms as mine. Both had purchase dates around March / April 2021. I can only assume some component failure.
