Why Does Samsung TV Say No Signal When HDMI Is Plugged In?

Before we delve deeper into the problem, you need to understand the root cause of it. If your TV shows no signal when the HDMI is plugged in, it could be due to several factors. Sometimes we overlook the more obvious causes and imagine the issue to be unsolvable.

  1. HDMI cable is not connected correctly/damaged. One possibility is that the HDMI is not connected correctly or could be loose in the port. Possibly the cable may not be functional anymore, and you require a new one.
  2. Clogged HDMI port. The port or the HDMI cable could be clogged with dust or other fine particles which impair the connection.
  3. The source device is faulty. Moreover, the source device could also be faulty, so try a combination of solutions to get to the bottom of the issue.
  4. Broken port. If none of these are the reasons behind your TV showing no signals, there could be a technical fault with the port, which may require you to consult a technician.

This process could be described in a list of steps. Although fixing the obvious issues is relatively easy, it is still worthwhile to explore the problem in depth by trying all possible solutions.

1. Reset the HDMI Ports

First, let’s start our troubleshooting with a good old reset. Follow these steps:

  1. Power off all of the devices connected to your TV via HDMI cable.
  2. Disconnect all of the HDMI cables from the TV.
  3. Turn your TV off.
  4. Unplug it from the wall for 10 minutes.
  5. Press and hold the TV’s power button for about 30 seconds.
  6. Plug all the HDMI cables back into the TV.
  7. Plug your TV and the devices back in.

2. Factory Reset Your TV

This is usually one of the last things we recommend to test out. But in this case, factory resetting has proven to be pretty effective. Remember, you will lose all of your stored data by using this last resort option.

  1. Open Settings.
  2. Select General.
  3. Select Reset, enter your PIN (0000 is the default).
  4. Select Reset.
  5. To complete the reset, select OK.
  6. Your TV will restart automatically.

Here is another way that is better at targeting the HDMI-related issues:

  1. Power off the TV and unplug it for 10 minutes.
  2. Disconnected your external devices and all the cables.
  3. Press Mute, 1, 8, 2, Power on the remote one by one in that order(or hold the exit button for 30 seconds).
  4. TV will turn on with Factory Reset screen.
  5. Chose “Option”.
  6. Chose “Factory Reset”.
  7. The TV will automatically turn itself off.
  8. Pressed “Power”.
  9. TV will turn on with the original set-up menu.
  10. Plug in each of the devices and HDMI ports.

Tip: Connecting one HDMI cable/device at a time might also help in getting the signal.

3. Check For Software Updates

If this does not solve your issues, then you should try to update your Samsung TV’s software from the main menu.

  1. Go to Settings.
  2. Select Support.
  3. Select Software Update.
  4. Select Update Now.

4. Check Your HDMI Cable

Verify that the HDMI is plugged into the correct input and the source device is powered on. Additionally, inspect the cable and the port to make sure there is no dust in them and nothing seems damaged or bent too much.

5. Check the Source

Select the correct source on your TV for the corresponding HDMI port. For example, if the cable is plugged into HDMI 1, then select that option on your TV.

6. Check your Connected Device

Make sure that the connected device you are using is actually powered on. If it doesn’t turn on, then you need to contact the manufacturer of your external device to solve the issue.

Also, if you turn on your TV first, then the external devices, try to change that order. Turn on your external device first, then your TV. That might make all the difference.

7. Try Unplugging the Cable

Unplug the HDMI from both of the devices and connect it again. Firmly pull it out of both devices, then plug it in the source device first and then the TV.

If this fails to work, try plugging the cable in another port and choosing the TV’s corresponding channel. If this works, your original port may have an issue that would require professional troubleshooting. If not, continue with the rest of the steps described below.

8. Use a Different HDMI Cable

Try a different HDMI cable that was not being used earlier. Make sure to use a high-quality 4K HDMI cable. By using a different cable you can figure out whether there is a problem with the cable or with the TV.

Tip: If you are using an old HDMI cable from your previous TV, chances are you will need to upgrade to a 4K HDMI cable.

9. Try a Different Source Device

Try a different source device that could be connected to the TV through the HDMI. Plug the cable in the same ports to determine where the issue is arising from.

If another device is connected to the TV, change its ports, or use its cable to locate the origin of the issue.

  • If the new device is working in another port, then there is a problem with the original source device.
  • If the original port is not working, but the other device is working in another port, then there is an issue with the original port.
  • If the new cable is working in the original port, then the original HDMI cable needs to be replaced.
  • If the cables and ports are working, there could be an issue with the source device.

10. Talk to Professionals

If no method works, consult a technician or Samsung directly for an opinion on fixing the TV or the source device where the issue was located. They could either schedule a service or repair any parts with a technical problem.

You can use any steps that we have described previously in this article since they are closely related and often have the same origin, plus here are a few more things to test out.

Change the Channel

Again, start with the easiest solution i.e. change the channel to see if the rest are working.

Reset your Samsung TV

Reset your device by unplugging the TV from the power source for 60 seconds and then plugging it in again. As tempted as you may be, wait the entire period for the system to reset properly.

Once this is done, turn on the TV and open the corresponding HDMI channel. You can figure this out by looking at the HDMI port, which mentions which channel the port uses and then locating it through the Source button on the remote.

Usually, this fixes the issue, and you may not need to proceed with the rest of the solutions. However, if your issue is unresolved, you can explore the other steps.

Reception Problem

There could be a reception problem from the antenna or the cable to the TV (if one TV works in the household while the other does not, your TV may need to be repaired). To resolve the reception issue, you should consider whether the source e.g. satellite dish, is positioned correctly.

Because they could be nudged by high winds, passing obstacles, or obstruction in movements. Moreover, the cables are likely to be damaged due to the normal wear-and-tear or weather conditions such as rain, snow, and humidity. You could inspect the wires from the outer side to detect any damages as any abrasions would be apparent.

Check the Input Settings

You could also review the input settings on the TV using the remote control. Ensure that the cable is connected to the correct port.
