    Samsung UE46C6700 mainboard replacement

    Did change the mainboard to a brand new one from Samsung. But, the set will sometimes go into standby, through the normal "shut down" routine with the music and all that.
    What the hell is this?

    Maybe it needs a firmware update, or reset to factory settings from the service menu.

      I assume it will have the latest FW since the board is produced in 2013.03, but maybe you're right.

          Gosh, think if that is the case!?!?
          Before replacement the set turned itself on and off all random. It's way better after mainboard replacement.

            Well, my bad.
            This time the mainboard was not to blame. When disconnecting the touch pcb, the set does not turn itself off. Also verified by another known good working touch pcb.
            Oh well...

            Is this a common problem on Samsung's?

              It's a common fault with all TVs using capacitive touch PCBs.

                Dell Latitude 7420 - Touchscreen not working since Mainboard replacement
                by Mirenia
                Hi everyone,

                I've got a little "problem child": my Dell Latitude 7420 2-in-1, which had a faulty mainboard.
                I replaced it, but ever since, the touchscreen no longer works — and honestly, I’m running out of ideas…

                In Windows Device Manager, I just see an I2C HID Device with error code 10. Sporadically, the touchscreen is recognized correctly for just a few seconds, but I haven’t been able to determine under which circumstances this happens.

                The touchscreen also doesn’t work in UEFI/BIOS, although it’s enabled...
