powers on + beeps briefly for a second displaying a blue light then powers back off
red shorted (0.3ohms) , blue not shorted
shorted inductor

top of the board

back of the board

mosfet? end of the back of the board shorted trace (I can't find a datasheet)

I don't have voltage injection + thermal yet but I'm in the process of buying both.
I am wondering where to progress through to next. The short seems so localised to this single area that I am tempted to start removing the ceramic caps but wondering if anyone has any further input.
- checked all fuses ok
- checked for voltages, found 12v, 5v, 3.3v, 1.8v (I am not 100% sure where to successfully check for all)
- started checking each inductor ohms to ground, all ok apart from a 1R5 near the DCIN, shorted 0.3ohms
- checking components around the inductor appears a small plane on the front of the board is shorted progressing through to a plane on the rear side
- surrounding circuits not on this plane are not affected
- I have check caps around the board in each various circuit for a similar short and have found none (so far)
- everything appears localised to this single area
- I did remove the mosfet on the right (stupidly) as I had a lapse of judgement and forgot the inductor to the right was still in circuit. I tested it off board anyway and it's fine
