LG’s Full HD televisions sometimes experience a glitch in HDMI-video transmission — the video signal is sometimes delayed or interrupted. This issue can affect videos on analog and digital channels, as well as video games played through the HDMI port.

When your LG TV’s HDMI port doesn’t work, it’s most likely a problem with the motherboard. A replacement motherboard will restore HDMI functionality and is available for purchase here. However, you can try restarting your TV first to see if that fixes the problem.

You may have even called LG support or LG customer service phone number trying to resolve the issue, but you’re still facing the same problem.

If that’s the case, then don’t worry. This article will tell you some possible reasons why your HDMI stopped working and how to fix it on your own.

HDMI Port Not Working On LG TV -Troubleshoot And Diagnosis

HDMI Port Not Working On LG TV

If you’re using an LG TV, and your HDMI port isn’t working, then this guide is for you.

1. Check HDMI Port And Cable

If there are any problems with the cable or the picture, be sure to check your cables, HDMI ports, and input sources on both the TV and the console.

HDMI incompatibility with some LG TVs can be due to improperly installed cables or other issues with the devices connected to them.

You can easily begin troubleshooting your LG Smart TV using the TV’s Quick Setup Guide. The first step is to connect a device that you know works with the television, such as a Blu-ray player or cable box. Next, turn on the connected device and verify that it’s working properly by playing media.

You won’t be able to connect your device to your TV if the HDMI connection is having issues. You can troubleshoot your HDMI connection issues by checking out the following tips:

  1. First, check if the problem is with the port or the HDMI cable by using another cable. If you can’t find any problems, replace the HDMI cable and see if that fixes your problem.
  2. Check the port HDMI cable is connected to on the TV. It may be necessary to switch over to a different HDMI port in order to connect your console.
  3. Replace your HDMI cable. Connectors can wear out over time, causing intermittent connectivity issues.
  4. Inspect the pins on your HDMI link device for damage. If you see any bent pins, contact the manufacturer of your console or video game to replace it.
  5. The HDMI port on your TV is a fragile component that can get damaged if you’re not careful. To check, look at the metal around the port. If it’s bent or broken, the metal is probably the cause of your problem. In this case, we recommend replacing the HDMI port.

Any product that comes with a cable has pins and receivers—if the pins are frayed from overuse or inadequate protection, or the receivers are falling apart, you may have to replace a component of your TV. This is an easy fix for most people, but if you’re not confident in your ability to handle this on your own, you can always contact a technician to do it for you.

2. Motherboard Is Shorted Out

When the HDMI ports on your LG TV stop working entirely, it may be time for a motherboard replacement. If the HDMI port is one of several non-responsive ports, there’s a good chance that your motherboard has shorted out and needs replacing.

LG tv motherboard is a bunch of small parts on the motherboard. They are responsible for the various features and functions on the LG Smart tv. Every time you run into problems with your LG smart TV, you may need to replace this part or repair it.

Before you begin to disassemble your TV, make sure you have all of the correct replacement parts on hand. And remember: always make sure to contact LG’s customer service department if you run into any difficulties while repairing or replacing components!

If a part of your LG TV is not working anymore, there are two things you can do. You can either replace it or fix it. Here are the steps for replacing the motherboard with a new one:

  1. Remove the screws on the back of your TV that secure the back panel. If you do not find any screws, use a flat-head to pry the cover off.
  2. Disconnect all cables and connectors from the motherboard.
  3. Unscrew the board from the LG TV wall. Slide the new board into place.
  4. Insert the screws to the back of the TV and attach the new motherboard.
  5. Tug on those cables and reconnect them.
  6. Make sure to reattach the back panel to your tv.

3. Reflow Your Motherboard

The LG HDTV you bought has a problem. It doesn’t detect HDMI signals. This can cause serious problems with your streaming service and other devices attached to your television, and it also indicates a larger problem with your motherboard.

Some owners may even prefer not to bother with contacting a technician or buying a new replacement. In those cases, one troubleshooting method that has worked wonders for many users is as follows.

Some people have recommended that you reflow your motherboard to get a better HDMI connection, but this can be pretty risky. If you’re going to do this, we recommend that you use safety gear, including anti-static gloves.

Ever had a problem with your LG TV? Here are the steps to heat the motherboard to restore its functions:

Ok, let’s get started! First, turn the TV over. Take the back off the TV. Carefully detach the stand. Remove the motherboard.

Preheat your oven at 385°F. Place the large motherboard on a mug and place it into the oven. Allow it 10 minutes to bake. Wait about 25 minutes for it to cool. Attach the LG TV motherboard.

In order to fix this kind of problem, it is recommended to remove the motherboard and heat it up in a normal oven for 5 minutes at 200 Celsius degrees. This will soften the solder and allow you to reconnect the damaged cables. After the soldering repair, make sure that you let it cool down for 25 minutes before using it again.

4. Check HDMI Connection And Resolution

If the HDMI on your LG TV doesn’t work, the best way to troubleshoot is by unplugging all HDMI wires and then waiting for 10 minutes to reset the device’s mechanics and then turning it back on. After this, plug in the power cable and HDMI wire. If there are any improvements, you should be good to go.

LG’s TVs have an HDMI input that sometimes doesn’t function. Instead of working right away, the resolution on the TV may be set to “auto.” This problem is caused by a miscommunication between the TV and whichever device you’re connecting.

For a stable HDMI connection, the resolution of both your device and your LG TV must match. The LG TVs comes with built-in screen resolution settings — and it is important to set the right one for optimal viewing experience and the best possible audio-video synchronization.

If your device is higher than 4K, you may want to check its resolution and adjust it to the native resolution of your television. Generally this is between 420p and 4K.

5. Disable HDCP

The HDCP standard is a form of content protection encoded into the HDMI transmission stream. The standard was developed to prevent unauthorized access and copying of copyrighted material that are sent via HDMI connections and devices.

Setting up a connection between an HDMI device and LG TV can be tricky. All devices in the HDMI chain must be registered to communicate through the HDCP standard. If your connection keeps cutting out, it means one of the HDMI-attached devices isn’t accepting the encrypted high-definition content encoded in the HDMI signal.

To fix this, try turning off HDCP on your machine and see if that fixes the problem. Alternatively, disable your TV’s “deep color” function. According to some users, this has helped them to resolve issue.

If you have an LG TV, you can disable the deep color on it by following these steps:

  1. Navigate to the settings menu for your TV.
  2. Scroll to the bottom and select “All settings.”
  3. Select the “Picture” item on the left.
  4. Go to Additional Menu Settings.
  5. Choose “HDMI Ultra High Definition Deep Color.
  6. Now select the HDMI port in which your device is connected.
  7. Press the remote control’s button for the appropriate mode to turn it off.

6. Disconnect Amplifier

If you’re trying to use your LG TV with a home theatre system connected to an AV amplifier, the TV and the amplifier could be conflicting with each other. Check your amplifier’s manual to make sure that the HDMI input you’re using corresponds to the input on your TV.

The amplifier should be configured to accept the LG TV HDMI connection.

You can also give up on the A/V receiver and connect the video interface directly to the TV. The problem is most likely with the A/V receiver.

Let’s say you have an analog connection to your A/V receiver. Once the signal is received, it won’t be translated to HDMI for transmission to your TV.

LG TV HDMI No Signal

When you’re connecting your LG TV to an HDMI cable and you suddenly see a black screen with the message “No Signal,” it’s possible that your input resolution is set incorrectly.  To fix this issue, try these steps:

Press the “Input” or “Source” button on your remote or the buttons on the side of your TV to display the devices connected to your TV.

Make sure your TV is connected properly. Turn off the TV and unplug the HDMI device from the HDMI port on the back of the TV, then wait for one minute before plugging it back in.

When your LG TV is no longer able to receive a signal via its HDMI port, it’s likely a result of a mother board malfunction. This can be resolved by purchasing a new motherboard for your LG TV that supports HDMI functionality. Alternatively, if you know how to solder and have the proper parts, you may be able to add support back yourself.
