I am Ebata, the resident "maintenance person" of the Ebata family.

In the Showa period, there was a concept that if you "beat it, it will fix itself," whether it was a TV or a stereo.

Nowadays, "unplug it and it will be fixed.

Nowadays, it is rarer to find a home appliance that does not have a built-in computer (microcomputer).

And microcontroller appliances that are left on can accumulate bugs and stop working.

However, in both the past and now, when you do it at "bad timing" or "bad luck", the appliance may not fix it, or it may break completely.
