Remember when you would visit your grandparents and they had the huge oak box with a TV in it? You go back to visit 20 years later and the same TV is still playing reruns of Andy Griffith. What happened to those quality built TVs?
In 20 years I’ve owned 8 TVs, and they all have failed me. You can’t get them repaired because to replace a button costs $500 and a new TV will cost you $550. So just toss it into the landfill and get some new tech.
