if you can, open the box, that sort oof repair in the wire done close to
the box is likely fail again soon.

Some boxs have screws hidden under labels, or under plastic plugs, or
little rubber feet.

Some boxes clip together, others are glued, still others are full of resin.
the glued boxes will often open if tapped repeatedly and lightlynear the
seam with with a hammer.

It's almost certainly electric.

when you get the box open be careful. some parts near the power inlet could
hold a high voltage.
