DABLYDMB8E0 Rev E.
totaly dead with no power, only i get 19v on the source of the first mosfet AON6414A on the drain i get 0.5v , changed it with same results
i removed the second mosfet with the same result

Please attach schematics so we can help.
Either the mosfets are bad or they aren't "switched on". Measure gate voltage.

Re: DABLYDMB8E0 Rev E.

i cannot find the schemtic,
the gate is 0v

Re: DABLYDMB8E0 Rev E.

is that the right board number, DABLYD or DABLID

dablyd, i forgot to mention that there is 0A when i test it, no current at all

Attach the files to your message directly.

Check both MOSFET for short across drain/source/gate.
Measure resistance to ground after 2nd MOSFET.
