You are currently viewing Is Your TV Giving You No Signal When You Plug in HDMI? Here’s What You Need to Know!

Did you recently notice that your television is not providing any signal when you connect via HDMI? Try switching to another input on the remote; this should rectify the issue. If not, then it might be time for an upgrade!

Are you experiencing difficulties with your HDTV and cannot seem to access Netflix or YouTube? Don’t fret! Here’s what could be causing it and how to rectify the situation.

What to Do When You Have No Signal When You Plug in HDMI?

If your new HDMI television has no audio output when connected to an already-installed home cinema system, there may be a basic fix. Ensure that the device is switched on and its input selected.

If you’re experiencing audio issues after plugging in your HDMI cable between two devices, try unplugging it and plugging it back in again. If this does not help, return the cable for a replacement or contact the manufacturer for help!

1. Make Sure Your TV is Turned On and Connected Properly

Before we delve into what adjustments you can make to solve your HDMI signal loss conundrum, let’s take a look at why it might be occurring in the first place.

Before you get too concerned with the particulars of troubleshooting your TV’s HDMI port or cable, simply ensure that your device is plugged in correctly and turned fully on – otherwise any sporadic issues could be attributed solely to network connectivity.

2. Check the HDMI Cables

It’s a common misconception that all HDMI cables are created equal; rather, there exists a bewildering array of differences between them. For instance, the most recent standard features a 2-m length and is therefore suited for applications such as HDTVs; meanwhile, myriads of other lengths exist allowing connection to computers or even consoles with an added advantage of support for HDR outputting.

If one of your HDMI cables isn’t working, it could be because it is not sufficiently long. In order to ascertain if this is the case, simply connect the requisite number of active devices – one after another – until you reach the maximum attainable length before attempting to plug back in.

3. Check to See Whether Your HDMI Source Is Speced for 4K/High Def

If you’re using an inexpensive HDMI cable or a dongle, it may not support your 4K resolution. A solution? Try this: assess which of your components can output at that level – and then select the one that provides optimal performance!

Harmon Kardia, vice president at Dolby Laboratories claims, “You’ll find that most newer televisions (even those with lower price tags) usually feature HDMI ports that can deliver 4K video signals.”

4. Test Your Other HDMI Ports and Cables

  • If you are using just one accessible HDMI port on your television, then the device may be limiting your options to obtain a signal. In order to maximize your connectivity capabilities with all devices while taking advantage of multiple displays simultaneously – it is imperative to test all available ports and cables before addressing any possible issues.
  • Ensure that you have fully tested all cables, including power cords – as well as each and every DisplayPort, Mini DisplayPort, or Component cable connection in your home! This will provide an expedient solution for when there’s not enough bandwidth for streaming media such as movies or live TV shows.

5. Test Your Older Component Video and Audio Out Ports

  • If you observe that your TV gives you no response when connecting via HDMI, it may be time to check the other video ports on your AV set.
  • The Component Video port or Component Video Out or YPBPR (Yellow/Blue/Yellow-Blue) is typically found beside the coaxial cable input and is utilized for outputting standard analog signals in both stereo and quad audio formats. Older high-end TVs typically would use this type for audio/video connectivity!
  • Check out your Component configuration. If yours does not have yellow-blue pins, then try using another component connection for testing – like S-Video and composite outputs.

6. Try Another HDMI outlet

If you continue to experience trouble with your signal after making sure you’ve secured a suitable connection, then it might be wise to invest in another HDMI port.

In some cases, your cable modem or router may be blocking the signal from reaching its intended destination. Plugging in a different outlet could result in an entirely new source of input; allowing you to enjoy clearer picture quality!


Even the most conscientious of TV connoisseurs may encounter an issue or two when connecting a brand-new piece of AV gear. If you’re encountering difficulties with your television when using HDMI cords, don’t panic!

By taking the necessary steps to rectify any issues, you can ensure that your screen remains in optimal condition for years to come.
