Nokia 105 (2019) Dead Solution – Full Input & Output Voltage Test | 100% Working Hardware Fix

If your Nokia 105 (2019) is completely dead, not powering on, or showing no signs of life, this guide provides a 100% working, hardware-tested solution.
Many technicians face this issue due to battery faults, input voltage failure, power IC damage, short components, or track cuts.
Here you will find the full voltage test points, power ways, and dead solution repair method for Nokia 105 (2019).

🔍 Symptoms of Nokia 105 (2019) Dead Problem

Phone not powering on

No charging indication

No vibration or display

Dead after water damage

Dead after using wrong charger

Sudden power off and no response

⚡ Nokia 105 (2019) Input & Output Voltage Test

Use a multimeter and follow these tested voltage points:

1️⃣ Battery Connector Voltage

Input: 3.7V to 4.2V

If no voltage → check the battery line, jumper if needed.

2️⃣ Charging Input Voltage

Check voltage at the USB connector pins

Expected: 5V input
If no voltage, replace the USB connector.

3️⃣ Power IC (PMIC) Output Voltage

Test for the following PMIC output lines:

1.8V line

2.8V line

3.0V/3.3V line

If any line is missing → Power IC may be faulty.

4️⃣ On/Off Switch Test

Check continuity between power button and board

If broken → jumper the line

5️⃣ Check for Short Circuit

Set multimeter to continuity

Test battery connectors and power lines
If shorted → Remove short capacitors.

🔧 Nokia 105 (2019) Dead Solution (Hardware Tested)
✔ Step 1: Clean the Motherboard

Clean with isopropyl alcohol to remove moisture and carbon.

✔ Step 2: Check Battery Connector

Loose or rusty pins → Resolder or replace.

✔ Step 3: Check Charging Port

If damaged → Replace.
If charging but not powering → Check PMIC output voltages.

✔ Step 4: Heat the Power IC (PMIC)

Give light heat to the PMIC
(SMD-safe, low temperature).

✔ Step 5: Replace Power IC (If Needed)

If no output voltage appears even after reflow, replace the PMIC.

✔ Step 6: Make Jumper for Broken Tracks

If voltage is not reaching the CPU or battery point, make a jumper following the diagram.
