Hisense TV Has Sound But No Picture

Occasionally every Hisense TV has issues. One of the more common issues you may encounter is that the TV has sound but refuses to show a picture. 

Hisense TV Sound No Picture

Your Hisense TV may play sound without a picture for several reasons. Most commonly, it’s a problem with the TV backlight, a failure of the timing control board, or that you have enabled the power saver mode on the TV. 

Today we’ll get into these problems a little more in-depth and discuss some solutions. Let’s get started. 

Why Your TV Is Not Showing a Picture

As I mentioned, there are a few reasons your TV would play without a picture. Some of these issues are more serious, but usually, it’s a simple fix

If your TV is a smart TV, it’s nearly guaranteed to have an energy-saving mode. While the energy-saving mode is downright helpful in some situations, it can be more of a nuisance than anything if you aren’t familiar with how it works. 

Another issue you face with LCDs, especially, is that the backlight can go out with time or if the TV gets damaged somehow. Luckily, this is a reasonably easy fix. 

Finally, the TV may not show a picture because of an issue with internal components, such as the timing control board, also known as the T-Con board. The T-Con board controls all sorts of things display related to the TV, and an issue with it can cause a lot of issues. 

Let’s look at each of these problems in a little more detail. 

The TV Is in Energy Saving Mode

Energy or power saving mode is a feature of most newer TVs, and once you get used to it, it often turns out to be a favorite feature. 

Essentially, energy saving mode shuts off the TV display while leaving the background sound playing. The television is off during this time. 

The energy-saving mode on your TV works much the same on your computer. It’s advantageous if you’re the type that enjoys listening to background sounds as you sleep because you can enjoy the sound without being exposed to harmful blue light that disrupts sleep. 

However, if you’ve recently purchased a new TV and aren’t familiar with the energy-saving mode, you may be pretty confused right now. If your TV seems to be in perfect working order aside from occasionally not showing a picture, chances are high that the problem is that it’s in energy-saving mode. 

The good news is that this is a straightforward fix. You’ll want to go into your TV settings and turn off energy-saving mode. If you want to leave it on, but you also want it to show a picture at the time, you should be able to press any remote button, which will turn the display back on. 

The TV Backlight Has Gone Out

If the picture has gone out and stays out, it’s likely a problem with the TV backlight. The backlight essentially controls how much brightness you see on the screen. 

You would expect to see a few different things possibly happening in this situation. 

  • The TV will turn on without any display of the picture. This will be the most apparent sign but will only manifest if the backlight has completely burned out. 
  • The screen is dim. If the screen is dim, the TV backlight is on its way to going out. In this case, it’s defective, and still time for a replacement. 
  • The screen may start flickering. This will usually happen before the display completely disappears. 

If you believe that your TV backlight has gone out, then you’ll want to take it to a professional and get it examined. You may need to replace the backlight at this point, but typically they aren’t too expensive. 

The TV Is Experiencing Internal Issues

There are quite a few internal issues that a TV may be having, and most of our solutions will center around fixing these. The most common problem regarding display issues is a timing control board failure or disruption

The timing control board affects nearly every factor of the display. When it begins to have problems, you may notice that the TV begins to flicker, show lines, and eventually loses the display completely.

Unfortunately, timing control board problems are relatively common, and sometimes it’s best to replace the TV if you’re having consistent issues with it. 

Some Easy Solutions for a Black Screen With Sound

Alright, now let’s talk about some solutions you can try. Usually, if the TV has a problem with any of its internal components, the solutions below will temporarily fix the problem. 

1. Power Cycle the TV

Power-cycling a TV essentially does a hard restart on the TV. It shuts down all the extra information the TV is holding on to and puts it to sleep for a time. 

To power-cycle your TV, you’ll want to unplug it and leave it unplugged completely for at least thirty seconds. Once the time has passed, you can plug it back in and allow it to restart.

Power cycling will reset the TV’s internal components and fix the issue in almost every situation.

2. Check the Backlight With a Flashlight and Replace It if Necessary

If you think you may be dealing with an issue with the backlight, this solution is for you. It’s really easy to test the backlight. 

To test it, you’ll shine a flashlight at your dark display and see if images come up on the screen at that point. You’ll want to be in a dark space while doing this. 

If you see some images with the flashlight, it’s a sure sign that the backlights are the problem. In this case, you can take your television down to a shop and have the backlights replaced for minimal cost. 

3. Factory Reset the TV

Sometimes display issues happen because of settings with the TV itself. It can be impossible sometimes to figure out what has gone wrong. If you find that the power saving mode is off, the backlight is working, and so on, you may need to factory reset your TV at this point. 

To reset your TV, follow these instructions. 

  1. Turn on your Hisense TV.
  2. Look for the reset pinhole at the back of the TV. 
  3. Insert a toothpick into the pinhole and press for at least 20 seconds
  4. Wait for the TV to reset.

Final Thoughts

If your Hisense TV has sound but no picture, it’s usually a problem with the timing control board or other internal components, a problem with the TV backlight, or because you have specific settings enabled. 

Most of the time, it’s an easy fix, however! You may need to take your television to a professional, but try the fixes above first.
