The other symptom is that the power brick, which usually gets pretty warm, is

If the brick won't generate an output to the 5300, yet it gets extremely hot 
... much hotter than when operating on 120 volts (in North America) OR 240 
volts (overseas), then something is terribly wrong inside.

If it was flup-flupping, then the problem would be a short in the secondary 
side, so I suspect the problem is in the primary side or in the converter.

Usually, a primary side failure is catastrophic, and result in the fuse being 
blown.

Converter malfunctions are MOST difficult to troubleshoot, and the voltages 
involved are quite high ... about 340 volts.

A generic brick which produces 24 volts dc at greater than 1.88 amps could be 
used.

I'd look for one rated 24 volts at 2 amps.

The brick is indeed "autosensing". If the autosensing circuit was 
malfunctioning, I would expect a failure in the primary side, as that's the 
only place which the autosensing circuit has any effect.
