S9 No HDMI? Charging Port Diagnosis
Samsung Galaxy S9 HDMI Not Working? Charging Port Secrets You Need to Know
Introduction
The Samsung Galaxy S9 is still a reliable smartphone that many users enjoy for its sleek design, high-quality display, and versatile features. However, one common issue that owners encounter is the HDMI output not working when trying to connect the phone to a TV, monitor, or projector using a USB-C to HDMI adapter. For many, this can be a frustrating problem—especially when they rely on their S9 for screen mirroring, presentations, or streaming content on a bigger display.
In most cases, the issue doesn’t come from the adapter or the TV but from the charging port itself. Over time, the Galaxy S9’s USB-C charging port can accumulate dirt, suffer from wear and tear, or even develop internal damage that interferes with its ability to transmit video signals. Since this same port is responsible for both charging and data transfer, any fault can directly affect the HDMI output.
This guide will walk you through the most common reasons why your Galaxy S9 has no HDMI output, how to diagnose if the charging port is the culprit, and what repair solutions are available. Whether you’re a DIY enthusiast looking to troubleshoot at home or someone considering professional repair, this article will provide practical insights, tips, and expert recommendations.
By the end, you’ll understand:
- Why the S9 loses HDMI functionality.
- How the charging port impacts video output.
- What repair or replacement options are available.
- Why visiting a trusted repair centre, like Sydney CBD Repair Centre, is often the safest choice.
If your Galaxy S9 isn’t connecting to HDMI, don’t panic—there’s almost always a solution. Let’s dive deeper into the problem and uncover what’s really happening behind the scenes.
The Samsung Galaxy S9 is still a reliable smartphone for many users, but one common issue that frustrates owners is when the device refuses to connect to an HDMI adapter or external display. Since the Galaxy S9 relies on its USB-C charging port for both charging and video output, any fault with this port can disrupt HDMI functionality.
If you’re experiencing this problem, here’s what you need to know about diagnosing and fixing it.
Why Your S9 May Not Output HDMI
There are several reasons why your Galaxy S9 might not connect properly via HDMI:
- Damaged Charging Port – Over time, the USB-C port can develop bent pins, corrosion, or internal damage that prevents stable HDMI signal transfer.
- Dust or Debris Blockage – Even small particles can disrupt the connection. Charging might still work, but video output often fails.
- Incompatible or Faulty Adapter – Not all third-party HDMI adapters are reliable. Samsung recommends high-quality or original accessories.
- Software Issues – Outdated firmware or glitches can occasionally interfere with HDMI output.
- Water Damage – Exposure to moisture can corrode internal connectors and disable the port.
How We Diagnose the Issue
At Sydney CBD Repair Centre, we perform a detailed diagnostic process to identify whether the charging port is the cause of the HDMI issue. Our technicians:
- Inspect the USB-C port for visible wear, dirt, or corrosion.
- Test HDMI output using verified working adapters and cables.
- Check charging and data transfer to rule out partial faults.
- Run system diagnostics to confirm it isn’t a software-related error.
If the port is found faulty, we recommend a charging port replacement using genuine Samsung parts.

Replacing a Galaxy S9 charging port isn’t a simple DIY task. The phone is sealed tightly, with waterproofing adhesive and delicate components around the USB-C assembly. Attempting self-repair risks damaging the motherboard or display.
