OPPO R831K Shorted No Power Part II

It's another shorted board OPPO R831K due to overcharging. And as I have said on my post, Samsung J100ML/DS Shorted No Power Solution that not all shorted have the same solution. Like my older post on OPPO R831K shorted

This time I use the method on how to solve Samsung J100ML/DS Shorted No Power. I also use my power bank and put lacquer flow on the board. As I've expected again, I did determine the faulty component 'coz the faulty component has been boiled/burst out. Or should I say, melt? Whatever!

Just see images below. Replace it and problem solve!






Samsung J100ML/DS Shorted No Power Solution

I have here Samsung J100ML/DS Shorted No Power. The solution may vary. Because we don't know what will be the faulty component/s. My method on how to solve this Samsung J100ML/DS Shorted No Power is by using my power bank. I connect the negative terminal of my power bamk to the negative terminal of the unit. Then I put some lacquer flow on the Samsung J100ML/DS board. Then eventually I tap the positive terminal of my power bank to the positive of the board for 2 seconds. Then finally I got the faulty component. That is the capacitor as shown on the image below.
