A few solid-state components, at most a minor circuit board; failure means no display. It’s as if the on-off button stopped working, or a fuse popped.

Why this particular circuit is so prone to premature failure - and why designers can’t give us some kind of replaceable fuse in addition to or instead of - I don’t know but it’s amazingly common to have one go bad.

Not that you should, you know. Care, necessarily. Especially with a replacement on its way. ;-)

Definitely a good news item.
