Quite some time ago, I picked up a nice monitor that turned out to be a debranded (all OEM labels removed or covered) HP w2408. It eventually became erratic, refusing to turn on or return from power-save mode, so I took it apart. All the caps looked good and seemed to have low ESR, except for the big one in the middle of the power supply board:
It’s 30 mm in diameter, with 10 mm lead spacing, and stands a squat 26 mm tall, ignoring a millimeter or two of bulge in its should-be-flat black cap:
Having never seen one of that size before, I sent a note and picture to folks who sell re-capping kits for monitors, in the hope that they’ll have a lead.
Otherwise, it’s e-trash…
