To repair a short cell phone, first you have to delete its shorting to fix it.

1. Disassemble your phone and take out the cell phone PCB. Be careful not to damage it! Now remove the LCD, the camera and so on, because we only need the main board.

2. Thoroughly clean the entire circuit board with specific phone PCB cleaners, such as alcohol, spirit, IPA and so on, and now completely dry. After each step, you have to check to see if the shorting is solved. If not, go on to the next step.

3. Try to deep clean the PCB. There is a liquid that Emma is called Elma in the oriental country watch technician. If you don't have access to the HK solution, you can use any mild soap if you can solve it.

Note: Make sure you remove the LCD, camera, etc from the PCB before dipping the circuit in Elma. Also make sure, you have dried the PCB completely. It' s advisable to dry the PCB twice as water droplets remain below the chips on the motherboard.

If the short circuit is solved, you may think there are some dust particles that cause a short circuit. Dust is one of the biggest enemies of a smooth working circuit board. The other enemy is moisture. Here are the advanced procedure we must follow for your phone fix:

Two things we should consider:

1. The entire PCB is short

2. A component or IC on the PCB is short and making the entire PCB short.

If the PCB is short, we cannot dig it out and fix it! We will consider that any of the component or IC is short.

Check whether the resistor, capacitor, diode and other components are short circuited manually. Capacitors have more chance of being short circuit because they will burn with darker color. Remove it and check the short circuit with a multimeter. If it is gone, you have to weld a same working part in its position. If this problem has not been solved yet, continue the next step.

Connect the circuit board to the Cell Phone battery, press the power button and keep it in 10-20 seconds. Take out the battery and check immediately if there is any part or IC heating. The heating part is likely to be short. Remove it and check again. If there is a problem, replace the heating element / integrated circuit.

If there's still a problem, it's hard to fix it. You have to remove all the components one by one and check if the short circuit has gone or not. But because there are hundreds of such components on the phone's motherboard, it may take days or weeks, so it's not feasible! The only way to do it is to replace the whole motherboard if it's possible for you.
