HI there,

I am working on a Samsung One Connect Box Model SOC8002BB,
Fault happened in a sudden power cut.

SMPS MODEL: 65Q900B/75Q800B THL1B4401176AAM5RT1C0836

I have narrowed down a shorted Mosfet on the power board QM953CS.

Its a KEC KU 210N20P I am having no luck finding these at all replace.

Verify the markings on the mosfet is correct.
You maybe misreading it.
Post a clear pic so we can help.

Was the fuse blown?

This was verified under a microscope exactly what was writing on these mosfets

Looking at the rest of circuit I can not find any other issues. would I be safe to assume this is all that blew.
