Re. Must be a component issue.
Ah yes the "Capacitor Plague" (tm) which doomed many many (including mine) devices to a grisly demise.
I tried repairing some but the damage turned out to be pretty severe.
Looks like on older AMD boards when the capacitors fail it damages other parts.
Graphics cards also, had one where the capacitor bulge caused heatsink to move tilting it off the GPU and resulting in a fail.
Also more like schadenfraude.
Data point here: had an Ipad do this once also two S6's and a couple of Crackberries.
Seems to be common with certain batteries but you usually can't tell who the manufacturer is due to to them being wrapped in opaque black iWrap(tm) although did managed to get a part number off the underside of the iPad's cell(s).
