The Sony timer is a timer said to be devised by the Sony products.
Sony timer is started immediately after the maker guarantee goes out, and it damages the products.
In fact, such the timer does not exist. However, this is one of famous urban legends in Japan.
First of all, some consumers thought "the height of the frequency of this failure and timing which was measured will not be devised by the timer that it should break down after a term-of-a-guarantee end, either." And they used as a joke the word sony timer.
Generally it spread with the explosive spread of home video game console Playstation series.
