lg tv hdmi no signal laptop

 One of the most common problems that people face with their LG TV is connecting it to a laptop. There might be no signal coming from the laptop or there might be some other problem that needs to be resolved.

The first step is to connect the HDMI cable from the laptop to the HDMI input on your TV.

The second step is to turn on your TV and switch it to the input you plugged in your laptop.

The third step is to power up your laptop and wait for it to boot up and then start playing a video or movie that has audio.

The fourth step is to go into the settings of your TV and change its audio output from “TV speakers” or “external speaker” or “HDMI ARC” or “optical digital audio output” back to “TV speakers”.

What's wrong?

If you are using a laptop and your screen is blank, there might be a few reasons why this may be happening.

The first thing to check is the cable. Check if it is plugged in properly and if it’s not, plug it back in securely.

If that doesn’t work, try plugging the cable into a different input on your TV or monitor and see if that helps. If it still doesn’t work, we recommend you check with the manufacturer of your laptop for more help troubleshooting this issue.

Check the HDMI cable

We should always check the HDMI cable before we start using it, as a broken connection can cause a lot of problems. If you have a bad HDMI port or a broken HDMI connection, it will be pretty obvious when your screen starts flickering or you can't hear any sound from your device.

To check if the HDMI cable is working, you need to connect both ends of the cable and then try connecting it with another device - if there are any issues with the signal, this will show up.

Reset the HDMI Cable

Resetting the HDMI Cable

HDMI cables are used to transmit high-definition video and audio from a device to a monitor or television. Sometimes, when the HDMI cable is connected properly, the TV will not recognize it and will not display anything. In this case, you will need to reset the cable to make it work again.

Power Cycle The TV

When you want to power cycle your TV, simply unplug it from its power source for 10 seconds before plugging it back in. This should be enough time for any temporary glitches that were causing your TV not to work correctly in the first place to dissipate.

Restart your LG TV and Check for TV Signal Again

Restarting your LG TV can be done in two different ways.

The first way is to unplug the power cord from the back of the TV and plug it back in. The second way is to unplug your LG TV’s power cord from the wall outlet, wait for about 30 seconds, and then plug it back in.

If you still don't have a signal after restarting your LG TV, try moving it closer to the wall outlet or contact the TV manufacturer for help.
