[Machine Model]: Gigabyte_G41

[Board Number]: GA-G41MT-ST

[Fault Phenomenon]: No code running, the reset light flashes once every three seconds

[Repair Process]:

board is taken and does not run code on the power normally. The reset light flashes once every three seconds. It is estimated that the platform reset is 3.3V and the clock is 1.6V. Because there is a common problem with this motherboard, the serial chip, the network card or the BIOS may cause this problem. There are also these cases on Xunwei.com, so I quickly disassembled the serial chip, but it was not as I wished. I also got through all these common problems, and the results were the same. Why are the platens so difficult to repair? I thought to myself whether I was going to do a bridge, but I thought that the bridge would receive two PGs, VRMPWRGD and ATXPWROK to send platform reset.

slowly check, CPU powered by 0.48V, memory 1.5V, SPD, SM, VTT, and bridge powered by 1.05, CPU reset also exists, but it will jump. After checking this, I found that the CPU power supply is not correct. The real U on my page should be about 1.2V.

Check the power management chip to turn on and power supply, but the output voltage is wrong. Check the VID signal resistance value and find that VID07 is infinity. Check the drawings and find that VID07 is connected to pin 79 of IO, and the pin 79 of IO is also infinity.

is obviously broken. Since the distance between IO and the power management chip is too far, I can only run the line on the motherboard to see which side of the line is broken. Finally, when I ran to the back of the USB interface, I found a small scratch. I scratched it with a knife and found that there was a broken line. I made up for VID07 and IO's 79 foot.

finally connected to the diagnostic card and powered up. The diagnostic code trotted all the way to 96 and then FF. Due to the limited maintenance conditions in the dormitory, there was no screen to click. The diagnostic code should be illuminated.
