Well for a start, what is the voltage into and out of the big power inductor? One side should be fed from the PCIe plug through MOSFETS and will be a chopped 12v, the output side needs to 10v or more depending what the PIC is setup for. (Sidehack confirm?) Somewhere in this thread the output is mentioned.
Anyhow, if the low side of the inductor is less than that, probably dead PIC and the regulator/depot is working off of preset defaults. If the voltage is zero the I'd guess the FET's failed open but typically they fail as a short.
I suppose if you have a PICkit programmer you can follow the heart of this thread and try to readout what the PIC has stored in it. After saving that (possibly corrupt) file might as well see if the PIC can accept a reprogram for lower voltage better eff...
I have tried x5 psu's bit get the same situation/problem....I do not Know if i need a PIC programmer, as i do not know id]s my pic is withing ing the the correct parameters (Voltage).
I do have various pic programmers from over the years for old |NTL/Virgin pics, plus xbox etc....
I just need to the pic first, do my faults (AS ABOVE), relate to a dodgy chip ?
Can anyone confirm this, i've read and read/saved 70 odd replies, ans still do not know which pic it is it is ' i have a Willem/Nexus programmers..lol and i have a Pic Programmer somewhere, not sure where it is but remember putting in the 6 pin chips...MUST off been to to with 'Ful package TV' YEARS ago 15 years ago at least...
Thanks guys, i will keep searching..
the PIC is a 12F1572.. its powered by 3.3v
i used a pickit3.
the hex files are in this thread..
id start by flashing the default ones.. think its 720mV or something.. altho i run my s7s at 670mV with speed 600. it puts them at 4000GH/s and about 980 watts at the wall.
