If you encounter a situation where you are unable to see a picture on your television or the sound is not being transmitted through your Smart TV when using an HDMI connection, it is likely a sign that there is a problem with the HDMI port. The malfunctioning HDMI port can also have an impact on the functionality of your television remote when connected via HDMI, indicating an issue with either the HDMI cable or port.

If you are uncertain about whether your HDMI is causing issues with your TV, it is important to be aware of the following common symptoms:
- Abnormal picture display, such as a fuzzy, blurry, or sparkling appearance.
- No picture or intermittent picture display.
- No sound or intermittent sound.
- Discolored images on the screen or poor image resolution.
- Non-responsive television remotes.
When encountering these issues, you have two options. The first is to contact the television manufacturer for repairs or consider replacing the TV, which is generally the recommended choice.
However, if your television is no longer covered by warranty, repairing the faulty HDMI port may be your only option. It is essential to note that this process requires technical expertise and considerable patience.
Repairing the HDMI port involves working with delicate and intricate components, which can be both demanding and time-consuming. If you possess the necessary technical knowledge and feel confident in your abilities, you may attempt to repair the faulty port on your own.
However, it is crucial to emphasize that if you are inexperienced or lack expertise in handling electrical components, it is highly advised NOT to attempt the repair. Working with such components can be dangerous and may result in injuries or even fatal accidents.
How to Fix a Loose HDMI Port
The use of a thick HDMI cable is one of the factors that can lead to a loose HDMI port. When a thick cable is used, it exerts pressure on the port, causing it to expand beyond its intended limit.
What’s interesting is that most HDMI ports are connected to the chassis in a similar manner. This allows you to safely tighten the port using a screwdriver.
To access the HDMI port on your television, follow these steps:
Step 1: Position the television on a flat surface with the screen facing downwards and the back of the device facing you. This orientation will allow you to easily access the HDMI port.

Step 2: Locate the HDMI port on the back of the television. Check if there is a cable connected to it. If there is, remove the cable by disconnecting it from the port.
Step 3: Look for a small Phillips screw positioned at either the top or bottom of the HDMI port. Using a Phillips-head screwdriver, tighten the screw by turning it clockwise. This will help secure the HDMI port in place.
How to Repair an HDMI Port on TV
Here is a revised version of the steps to repair a broken HDMI port on a television:
Step 1: Begin by unplugging the television from the power source. Place the TV on a flat surface to prevent any damage to the screen. For plasma TVs, make sure they are not tilted beyond 45 degrees. Other types of TVs should be laid down to provide access to the HDMI port located at the back of the device.
Step 2: Repairing a broken HDMI port requires patience more than technical expertise. If the television casing is not easily removable, carefully remove it by unscrewing the necessary screws.
Step 3: Examine the broken HDMI port closely, paying attention to any damaged components. Often, the issue occurs between the port and the circuit board. Check for any broken connections in this area.
Step 4: If you identify a broken connection, carefully re-solder it back to the port from where it was removed. Take caution not to worsen the situation. Afterward, inspect the port to ensure that the pins are properly connected to the circuit board.
Step 5: In the event that the HDMI port is physically damaged, it will need to be desoldered. Before doing this, examine the connection points on the circuit board. The broader side of the HDMI port should face the solder-side connections.
Starting from the top left, PIN 1 should be located there, PIN 2 at the bottom left, and PIN 3 on the left side at the top. The pin numbering alternates between the top and bottom towards the right. PIN 18 is found on the bottom right, and PIN 19 on the top right. Remove the faulty HDMI port carefully.
Step 6: After removing the broken HDMI port, proceed to solder the new HDMI port onto the circuit board, ensuring that the pin connections match appropriately.
