🛠 Samsung A13 / A13 5G / M23 5G No Power Issue – Step-by-Step Hardware Fix for Technicians

Problem Overview

Many Samsung users and mobile repair technicians have faced the problem where Samsung A13, A13 5G (A135F/A136), and M23 5G suddenly show no power and appear completely dead. When connected to a PC via USB, the device is only detected as an Exynos 3830 USB port, and it neither boots nor charges.

At first glance, this problem may seem like a motherboard failure or eMMC damage, but in most cases, it is caused by a hardware-level capacitor fault, which can be resolved in just one simple step without replacing any ICs or using complex tools.

🔧 Affected Models

• Samsung Galaxy A13

• Samsung Galaxy A13 5G (A135F, A136)

• Samsung Galaxy M23

• Samsung Galaxy M23 5G

💡 Personal Experience (Rasel Ahmed)

As a professional mobile repair technician, Samsung A13 series phones often come to me with this problem. Customers report that the phone suddenly shuts down and cannot be turned on, while sometimes the device becomes extremely hot.

When such a phone is connected to a PC, the Device Manager shows only the Exynos port, and the phone remains unresponsive.

Through experience, I found that the issue is usually caused by a shorted capacitor near the eMMC. The repair is straightforward:

1. Carefully remove the protective metal shield over the eMMC, lifting three small tabs gently.

2. Remove the faulty capacitor—no IC replacement is needed.

3. Reassemble the board, and the phone powers on successfully.

I have performed this repair on three to four A13 and A13 5G phones, and in every case, this method worked perfectly. It saves time and ensures high success rates for this common Samsung problem.

🔧 Tools Required

• Screwdriver set for mobile disassembly

• Soldering iron or hot air gun

• Microscope (optional but helpful)

• Tweezers

⚙️ Step-by-Step Solution

Step 1: Disassemble the Phone

1. Open the back cover carefully.

2. Remove the battery, display, and mainboard connectors.

3. Take out the motherboard.

Step 2: Locate the eMMC Section

1. Identify the eMMC area on the motherboard.

2. You will find it covered with a metal shield / tin protector.

Step 3: Remove the eMMC Shield

• Carefully remove the eMMC metal shield using a hot air gun or soldering iron.

• Lift the three small tabs gently to avoid damaging nearby components.

Step 4: Remove Faulty Capacitor

• Under the shield, you will find a small SMD capacitor causing the issue.

  
  
  

• Carefully remove the capacitor. This component is shorted or faulty, and removing it restores normal power.

Step 5: Reassemble and Test

1. Reconnect all flexes.

2. Place the motherboard back into the phone.

3. Power on the device. ✅

   
   
   The phone should now power on normally, and the Exynos port will disappear from Device Manager.

💡 Why This Works

The faulty capacitor near the eMMC causes the phone to hang in Exynos mode, a low-level firmware recovery state. Removing this capacitor resolves the short, allowing the phone to boot normally without affecting other components or performance.

📌 Important Notes

• This fix is only for Exynos-based models showing no power but detected as Exynos 3830 in USB.

• No UFI, Easy JTAG, or flashing tools are required.

• Removing the capacitor has no side effects on phone performance or booting.

• Always test the board after removing the capacitor before full reassembly.

• Exercise caution when removing the eMMC shield to avoid damaging nearby parts.
