Why Does LG TV Say No Signal?

Weather Issues

Some weather elements can interfere with the normal transmission of signals. If the weather in your area has changed significantly, you could be a victim.

Wrong Input Source

Your LG TV comes with several input channels. Most LG owners who don’t know how to match the selection they’ve made on the TV are most at risk.

Malfunctioned Input Ports

If you are using the right input channel but the problem persists, your input ports might have malfunctioned.

Before making your mind whether this is the case, test the external device. Moreover, test whether your HDMI cable is not in the right working condition.

Motherboard Issues

If you are sure your HDMI ports, HDMI cables, and external devices are functional, double-check whether your TV’s motherboard is damaged. LG manufactures TVs that minimize the risk of motherboard damage. So, this is rare.

However, if you are a victim of motherboard issues, you have a reason to be concerned. The high cost of repair can cause some users sleepless nights.

Cable Box/Set-Top Box

You can also experience this problem if the service provider releases a new firmware and updates it in the background.

It means the provider has updated new satellite settings. But the TV is not compatible with the adjustments yet.

HDCP Errors

LG TVs are HDCP-compliant. This means you can run into a High-Bandwidth Digital Content Protection (HDCP) error if you are trying to access cable TV content through a non-licensed device.

Weak Broadcasting Signals

LG TVs provide top-quality picture quality. If yours is receiving broadcasting signals that can’t help it to produce the right pictures, you will likely see the no-signal message.

If you can see this message and don’t know how to fix it, you are in the right place.

In the next section, we provide a detailed step-by-step guide that seeks to give you all the steps you require to solve the issue.

TV Doesn’t Recognize HDMI

Software bugs can hinder your LG TV from recognizing the HDMI link. Inappropriate resolution settings can also do the same.

What to Do When LG TV Says No Signal?

1. Consider the Weather

Weather is a common culprit in some geographical locations. Since it is fairly uncontrollable, you might consider turning off the TV and cable box for a while until the signal resumes.

2. Check the Set-Top Box/Cable Box

If you suspect that the provider has uploaded new satellite settings, do the following:

1. Unplug the power cable from the TV.
2. Insert the cable once again.
3. Ensure the TV is switched off.
4. Pull out the viewing/smart card and allow the cable box time to cool.
5. Reinsert the card following the visible arrows (the chip facing forward).

3. Check HDMI Cable/Port Issues

To fix these issues, you should:

1. Ensure the connections are fitting tightly.
2. If step one fails, migrate to another HDMI port.
3. If your HDMI connector doesn’t stay in the port position, upgrade it to a self-locking one.

After following the above steps, you should get quality entertainment. This only applies if you are a victim of HDMI cable/port issues.

4. Check HDCP Error

For you to fix the no-signal issue, remove the non-licensed device.

5. Change Input Source

Since there could be a problem with your input source, change it.

There is no better way of doing so than using your supplied remote control. Here are the steps you should follow to change the source safely:

1. Check whether the remote has an Input/Source button. If so, press the button and select the input that matches the source.
2. If your remote lacks this feature, press the Home button, go to the TV’s Upper-Right corner for the Input Icon, and then click on it.

Note: If your inputs are labeled, click All Inputs to see each of the Port numbers.

6. Double Check the IN and OUT

1. Ensure the cable comes OUT of the other device.
2. Be sure IN goes to the TV.

Note: Ports labeled OUT send signals, which those that are labeled IN receive signals.

7. Check Signal Strength

If your LG TV is receiving weak signals, you shouldn’t expect to receive any picture until you do the following:

1. On your remote, press the Home button.
2. Click on Settings. After that, select QUICK SETTINGS.
3. Select Open channels, Channel tuning, and then Manual Tuning.
4. Click on Channel Watching.
5. Check the signal strength (If the channel signal is 50% or less, it is likely the underlying cause of the problem).
6. Be sure the cords from your cable box to the TV are securely connected.

8. Ensure TV Recognizes HDMI

Restart the TV. You can do so by following the steps below.

1. Unplug all HDMI wires.
2. Disconnect the power line for approximately 10 minutes.
3. Connect the HDMI wire and the power cable to see whether you’ve fixed the issue.

Check Resolution Settings. If the HDMI device has a video resolution menu, ensure it is not set to “Audio.”

9. Check Motherboard

If you’ve followed all the steps above and nothing works, your motherboard might have malfunctioned.

For the TV to continue working properly, you should purchase new parts for it.

If you are not an expert, don’t try to do this job. The motherboard is delicate and doesn’t require trial and error. Check out the best streaming sticks on Amazon that won’t let you down!
