    IT8718F replacement on GA-G31M-S2C

    Dear members,

    I have a GA-G31M-S2C mainboard with the IT8718F embedded controller.
    The mainboard does not turn on after pressing power button. the power button works fine and IT8718F is defective.
    how can I reprogram this IT8718F?
    If I replace this old IT8718F by another IT8718F taken from another used mainboard of different model, does the new IT8718F need reprogramming or resetting?

    Thanks

      IT8718F doesn't have an internal Flash. On desktop boards it's very rare to have an EC with internal Flash.

          Thanks,
          According to the schematics, no external flash is connected to IT8718. The bios chip is only connected to ICH. Then, where is the EC firmware saved?

              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...

              Sharp CC-60LE640U - after mainboard replacement, backlite turns on -- but cannot update firmware / see menu
              by AustinComputerDoctor
              Hello,

              I am looking / wondering if anyone knows where a good firmware download link is for a LC-60LE640U, the sharp support sight says the screen is archived but offers no links.

              I see backlite is active,

              but I cannot get the screen to return back to menus , etc

              This is all after replacing the mainboard...

              any assistance is greatly appreciated.

              Change name on tv after mainboard replacement
              by Ihandyrepair
              HI guys

              just quick question,
              I just fixed a dead Sony 55x800h, I replaced with a 65x800h board
              now works everything seems ok
              except that after factory reset, it will show 65x800h on the name,
              screen is 55 inch now

              I am guessing the size of the tv is programmed on the main board right?
              I could just change the name only

              or any way to flash the chip to make it to be a 55x800h instead?

              thanks...

              MASTER TL240 and new mainboard LW36BKC01
              by orcic
              Hello,
              I have an old MASTER TL-240 LED TV. Since it stopped working and it had a DVB-T receiver that is being dismissed in Italy, I've decided to replace the mainboard with a DVB-T2 one.
              The original problem was that when switching on the TV, the power LED was transitioning from red to steady blue, without showing video or audio.
              After checking some voltages on the power supply board (HKL-240101-B Rev. 1.4, HKL from now on) someone suggested me to replace the mainboard.
              Now I have some doubts about how to connect the new mainboard to the old power supply.
              First of...

              Macbook Air M2 A2681 Kernel panics after screen replacement
              by reformatt
              Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

              It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...
