Infinix Hot 9 Play X680 no charging flex ways

1. Inspect the Charging Port

The first component to check is always the USB charging port.
If the port is clean, solid, and shows no signs of corrosion or broken pins, we move on to the next step.

2. Test the Small Charging Board (Sub-Board)

• VBUS line
• GND (masse)
• Charging filters
• Small components connected to the USB
• If all readings are correct, the board is usually not the source of the problem.

3. Check the Charging Flex Cable (Interconnect Flex)

This is the most overlooked part of the repair process.
The flex cable connects the sub-board to the main motherboard. If even one track is cut or damaged, the phone will stop charging completely.

In today’s case, the fault was located here a broken charging line within the flex.

4. Inspect the Main Board

Only after confirming that the port, sub-board, and flex cable are working do we investigate the motherboard.
This is where the charging IC and power management circuits are located.
However in this repair, the motherboard was not the source of the fault.

The Real Problem: Broken Charging Line in the Flex Cable

Instead of replacing the entire flex cable, which increases cost and repair time, we applied a jumper wire repair to reconnect the broken charging pathway.
