I don't think a well-known brand of TV such as Sony, especially their sets from the '80s, before many makes became junk in a very short time, would konk out after only five years. One of my great-aunts had a 12" Sony color portable in the '70s that lasted over twenty years, and was used a lot since she liked sports and watching shows such as PBS's "Victory Garden", et al. When that set finally died, she bought another, larger Sony TV that outlived her. She lived maybe five years after getting that set, and to the best of my knowledge it was still working when she died. I don't know what happened to the set after that; it probably was inherited by another relative, who may still have it.
