They must have put a timer in it.
Typical for the cheap TVs you can buy on Amazon. They have nice panels and a bunch of really nice features. But they’re packed with spyware and adware, and they only last about 3 or 4 years.
Then, suddenly, the screen goes black forever. And you need to buy a new one.
I currently have a 43 inch TLC and it has some great features that I got for $200. I think I might have about a year left on it. But I knew that going into this, because I had, previously, a 43 inch from Vizio that died on nearly exactly the three-year anniversary of the day I received it from Amazon and first plugged it in.
So I definitely believe there’s some kind of timer inside of them that just causes them to blink out
