How To Fix Samsung Galaxy Grand Neo Plus Can Charge, But Can't Power On

Here's a Samsung Galaxy Grand Neo Plus GT-i9060 from my customer. He said that it normally charge, but it can't be on. Basically it's a power switch ways problem or the switch alone. Let's check the switch. 

After dismantling the unit I found that its switch flex is clean, no trace of dirt or corrosion. I suspected a rust membrane :) But first I check the switch connection by shorting the positive and negative switch connection. It's good. 

What I need next is to check the switch flex's membrane. And as I have expected, the membrane is rusty as seen in the images below. Just clean it and you are done.

Repairing iPhone 4 No Power

History: water damage

First thing first, that is basic troubleshooting

1. Open the unit, check if grounded/shorted. Not shorted/grounded. Also check board by visual checking.

2. Replace battery and try to power it on. Still can't power on.

3. Connect usb charger to laptop and see if it connect or asking for usb driver. No reaction.

4. I always do this, remove lcd and connect it again to laptop. Finally it connect! I thought LCD set was damage. but when I replace LCD set, still it doesn't power on.

5. Analyze.... While I'm thinking I notice a heat up on power IC and other neighboring components.

6. What I did is to connect its positive and negative terminal to power supply and found out that output current is not normal when you press power on(with LCD attach)

7. But when powered it on without LCD attach, current output is normal. Aha!

8. I Immediately check the LCD connector ways and here's what I've found:

Samsung S7392 Shorted Solution

Samsung S7392 that has a shorted board due to overcharging. The method I used is not very common. When you connect 1.3 voltage you must expect a capacitor heating up. But even 5 miinutes waiting, there's no capacitor that heats. So I decided to use my magic source, LOL! I used my power bank to supply a 3.8 voltage. I connect the negative terminal of my power bank to the negative battery terminal Samsung S7392. The I slowly tap the positive of my power bank to the positive terminal of the phone, and immediately one of the capacitor heats up.That's the deffective one :D I then remove the capacitor, and the shortage was gone. Hehe. Finally, jst replace it and you're done :) The cellphone was able to power on again, and back to normal.
