Measured at just over 4v.

Wall wart says 5.3v and 2.4 amps, and by the weight/size is an SMPS.

Using my bench top 5v 3 amp supply it works normally.

A new wall wart from Aten is 35 quid plus. ;-)

It'll be the output cap. Crack it open (it'll almost certainly be
welded shut. You can crack the seams carefully by squeezing them in a
vice) and replace the cap.

One of the youtube teardowns shows the use of a screwdriver handle
to whack it with can be surprisingly effective in that situation.

Whether is worth farting around when 5V 3A switch
mode wall warts cost peanuts tho is another matter.

Use a good quality 105 degC replacement.
Reassemble case with superglue.

Total cost about 50p.

The caps fail due to heat build-up in the case and no ventilation.

There is going to be **** all heat in a 5V 3A switch mode wall wart.
