Hello all,
Does anybody have a schematic and/or boardview of the Gigabyte GA-H110-D3A mainboard available? It would really help me out big time...
This board was donated to me in a known non-working state. In its previous life it was used as a mining board, so I suspected bad caps and a relatively easy fix. My intention is to use the fixed board as a testbed for a Truenas or Unraid build. The previous owner told me that the mainboard started to act 'weirdly' after replacing the originally installed Celeron for an i5-6400, varying from starting up irregularly to not at all. He couldn't reverse the situation by installing the Celeron back again. He could sometimes get it to start after swapping RAM modules, until that didn't work anymore either.
Inspection showed that every cap is solid aluminium and they all look fine. The socket is completely intact, no bent or broken pins. There are no visibly damaged or knocked off components. No shorts on any of the power rails and no shorted mosfets or VRM's either.
However, it does look as if the mainboard has been used in a humid/moist air environment, as a lot of smd components had some sort of thin layer of white chalklike stuff on their solder connections, as if moist had condensed there and corroded the solder. I removed as much of this as I could with a glassfibre pen, paying attention of course not to damage components, and wiping them clean with IPA afterwards.
Besides that, a copper trace had probably not been properly covered under a solder mask during production, and had corroded away completely. This trace leads from the PCH to the jumper used for clearing the BIOS settings. I fixed this missing trace with a piece of thin wire. I looked for other damaged traces, but this was the only one. Adjacent traces all had continuity when I measured them with my multimeter.
Sadly, in spite of all this, the board does not want to start. No leds light up, no audible beeps, simpy no sign of life at all. I did use a CPU that was on the verified list (i3-7100). As the mainboard doesn't start, I have not been able to restore the BIOS from the backup chip.
So, for a further more in depth investigation, I'm now in need of a schematic and/or boardview for this mainboard. Does anyone have these in his archive, and is willing to upload it here? Searching this forum and the interweb did not turn up anything.
Thanx in advance!
