Hello,
I am looking for a schematic for the GA-H55M-S2/SK 1156 motherboard. Seems like a hard to find one.
The current condition of the board it's as follows:
- had a power MosFET blown , with no other major damages and replaced, checked for shorts in the VRM, everything looks ok.
- for safety reasons replaced also the ISL 63333 CRZ
The board exhibits a power on /Off loop without beeps or any image. The ON state takes about 2 seconds, then Off and then back On and does this forever.
I would like to inspect more closely the Super I/O Power On circuit and a schematic would help a lot. In the meantime i ordered an ITE 8720F super I/O because this was a model that i do not have at all in my inventory and i suspect it as being the culprit for all this, but...no hard facts here.
If someone has the schematic and can share it, this would be great.
Thank you very much for your kindness.
Alex.
