According to the experience of repair, we can find out the fault of the component with the <\/span>rosin detecting <\/span>method.<\/span><\/p>\n

Soak some rosin with soldering iron and then smoke rosin on the surface of the relevant components on PP_VCC_MAIN. Apply a proper power voltage and find the rosin on C2859 melted.<\/span><\/p>\n

Judging by this, the fault is related to C2859. Because C2859 is a filter capacitor, so we can remove it directly.<\/span><\/p>\n

Repair tips<\/span><\/strong><\/p>\n

For issues like large current once connected with DC power supply<\/span><\/p>\n

Normally it’s caused by the related power rail which before press power button with some power leakage.<\/span><\/p>\n

The rosin inspection method or thermal camera detection method is quite easy to find out the shorted components.<\/span><\/p>\n

<\/span><\/p>\n

And as mentioned, after finding out the shorted component, just replace it or tick it off directly.<\/span><\/p>\n

(Normally, the filter type capacitor can be ticked off directly)<\/span><\/p>\n
