Friends,
It appears I've accidentally applied 19VDC to a PCB that should only run 12VDC.
The board now does not power on, even with 12VDC..
Using a thermal camera shows entire board remains COLD except one component (near power plug) that heats to 120C and higher!!
Suspected component is marked with "T" (slanted) and "BE", think/hope it is some kind of fuse, in photo just ABOVE the green power terminals and LEFT of the 16V capacitor (on right of photo)
Interesting part is measuring continuity across that component shows 0-reistance...
