samsung galaxy A50 not charging solution

Charging failure on the Samsung Galaxy A50 (SM-A505) is one of the most common hardware issues technicians deal with. Although the A50 is a mid-range device with a strong reputation, it still suffers from charging interruptions caused by physical damage, broken tracks, or faults in the charging pathway.

Samsung Galaxy A50 Not Charging – Complete Jumper Solution & Charging Ways Guide

This guide explains how to diagnose the issue correctly and how to repair the charging line using the jumper solution, especially when the flex cable or charging circuit has a broken path.

Understanding the Charging Line Flow in the Galaxy A50

Unlike many budget models, the Galaxy A50 uses a Type-C port and a dedicated sub-board connected to the main motherboard through a flex cable.

How to solve Samsung a50 charging problem?

Any interruption in this pathway—whether on the port, sub-board, flex, or main board—can stop the device from charging completely.

When diagnosing the A50 charging system, technicians must analyze the device layer by layer:

1. Start with the charging port
• Check for loose pins, corrosion, dirt, or physical damage.
2. Inspect the small sub-board (charging board)
• Measure VBUS input, ground (GND), and voltage filters using a multimeter.
3. Test the charging flex cable
• Ensure that all tracks from the sub-board to the motherboard have proper continuity.
4. Verify the charging ways on the main board
• When all previous parts are functional, the fault often lies in a broken charging line on the motherboard—requiring a jumper.

This systematic approach lets you locate the exact point of failure with precision.

Samsung Galaxy A50 Not Charging – Real Cause & Jumper Solution

In many repair cases involving the Samsung A50, the root problem is not the USB port or the battery, but rather a cut track on the charging pathway. This may happen because of:

• Moisture exposure
• Excessive pressure on the charging cable
• Wear from long-term use
• Damage during previous repairs

Instead of replacing the entire flex cable or sub-board, which increases cost, you can restore the charging function by applying a jumper wire solution to reconnect the broken charging line directly.

This technique is efficient, safe, and commonly used in board-level repair when charging ways are damaged.

⚠️ Important Safety Warning

Board-level repair requires careful handling. Before performing any jumper or soldering work:

• Disconnect the battery completely
• Use proper heat settings to avoid damaging nearby components
• Work with quality jumper wire (0.1mm copper wire)
• Avoid bridging wrong points—incorrect jumper work can short the PMIC or charging IC

This guide is intended for trained technicians only. If you are not experienced with motherboard repair, it is recommended to visit a professional service center.

⚠️ Risks of Incorrect Jumper Solutions During Charging Repairs

1. Risk of a Short Circuit

When reconnecting a broken charging line with a copper wire, even a small mistake can cause the wire to touch nearby components.

This may lead to a short circuit that can permanently damage the device or burn sensitive components such as the Power IC or Charging IC.

2. Possible Damage to the Motherboard

Any improper heating or soldering may lift pads, damage traces, or harm internal layers of the motherboard. This kind of damage is often difficult—or sometimes impossible—to repair, leaving the phone completely non-functional.

3. Damage to Nearby Charging Components

Working on the jumper without proper thermal protection may affect nearby tiny components such as filters, resistors, or capacitors. This increases the complexity of the issue rather than solving it.

4. Loss of Warranty

Opening the phone or working directly on the motherboard voids the manufacturer’s warranty. This eliminates your chance of receiving free repair or replacement services.

5. Risk of Burns or Physical Injury

Using hot tools such as soldering irons or hot-air stations without experience can lead to burns or injuries. Additionally, inhaling solder fumes frequently may be harmful to your health.

6. Potential Data Loss

A mistake during the jumper repair process may cause the phone to stop booting entirely. This can make personal data stored on the device inaccessible without advanced chip-level techniques.
