edit: I have already ordered a replacement since even if it isn't the power supply, these things seem to have a high failure rate anyways and aren't ce/ul so if they do cause a fire insurance might not cover it.
and consistent under load
is that 24v? If these things are barely operating within their tolerances to deliver that 24V, besides the extra-warm smelling power brick, as the supply heats up, that voltage may vary, and may "sag" under load - meaning when you plug your monitor in and it's driving the panel, backlight, driver board, it may sag below 24V - the "sag" under load is commonplace, and may be extremely so given we're operating these bricks out of range. Add heat buildup due to probably the guts working extra hard (VRM's etc), and as the power brick warms, the degradation may be too much for the driver board to handle.
Good point on the CE/UL, though if these things were the source of the ignition, I doubt there'd be much left of the label
- seriously though, it isn't worth the loss of life to find out. The ones I ordered didn't list UL approval, they were stamped CE with no listing # though. But they won't keep my coffee piping hot so I'm much more comfortable.
