it's a PoE camera and it stopped working. Using thermal image I identified failing component U22 marked as 16AF which seems to be buck convertor TI https://www.alldatasheet.net/datashe...62569DBVR.html. I took it out and It is inteed shorted on the output. However, after I took it out, the resistance between the output pads (on the board) still shows 190ohm, is that bit low?
Another issue is, seems to me I must be missing one of the tiny resistors R810 that should make up the voltage devider for the buck convertor. Honestly I did this months ago, I cannot...
