Jijia P106 power supply short circuit repair
The power supply of Gigabyte P106 was short circuited. The C1048 capacitor was replaced and the fault was repaired.
Machine model: Gigabyte P106
Fault phenomenon: card not recognized
Maintenance process: After getting the machine, the first thing to do is to supply power and measure the value. No abnormality is found. Plug in the computer to measure the voltage, and a 5V voltage will come out normally. There is no 1.8V voltage, and the voltage of the video memory core will not come out.

It is found that the value of 12V to ground is 0. No wonder there is no voltage. It was originally short circuited. Later, it was found that the capacitor C1048 was short circuited. Replace the capacitor C1048 and repair the fault.
