        the trace works so it's in the analog rectfier/divider area.
        why not use the working channel to follow the signal through the bad channel till you lose it?
        does switching ranges or going between AC and DC have any effect?

            Gigabyte GA-H110-D3A schematic/boardview needed
            by re-atari
            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...

            MSI GF63 12UDX-234XPT - MS-16R81 VER:2.0 - Schematic needed
            by camisao
            Hello,
            I need your help finding the MSI GF63 12UDX (Board MS-16R81 VER_2.0) schematic.
            I accidently inserted MSI USB a programmer that was connected to a board that has Neutral tied to GND, instead of connecting it to the USB-ISO that was on another port (Friday afternoon mistakes....).
            Now it doesn't start. 😏
            I've looked for burned parts but found none.
            The 20V from the adapter are ok and the battery has 12V if I disconnect the battery plug.
            I need the schematic to try to understand where there the problem may be or if it is repairable.
            Thanks!...

            Dell Chromebook 11 CB1C13 (Da0zm7mbac1 Rev C) schematic needed
            by c_vasiloiu
            It seems that the 16GB eMMC has some problems and I would like to install a bigger hard drive, a regular 2.5" SATA SSD drive. On a similar laptop schematic (Quanta ZM8 r1A) It looks that the CPU Celeron 2955U has some SATA ports available that may have some test points on the motherboard.
            Can somebody help with the schematic and to confirm if a SATA SSD drive can work with wires connected on these test points? Also a SATA SSD drive can work with +3.3V taken from the motherboard?
