Have you ever turned on your TV but heard no sound or no picture? It can be a frustrating experience, especially if you’re trying to watch your favorite show.

Fortunately, there are several things you can do to troubleshoot and fix this smart TV problem. To find out more about them, keep reading.

1. Double Check If It's On

The first thing to do when you encounter this issue is to double-check if the TV is actually on. It may seem obvious, but you would be surprised how often people need to remember to check this.

2. Check For Loose Connections

The next step is to check for any loose connections. This could include any cables or ports that are connected to your TV. Make sure that all of the cables are firmly plugged in and that none of them are loose.

Then, check if the cables connecting the TV to the power source, the cable box, and the speakers are all securely plugged in. If any of these connections are loose, the TV may not receive a proper signal, resulting in no picture or sound. 

3. Inspect For Broken Back Lights

Back lights provide the illumination for the picture on the TV, and if they are broken, you will see no picture. Check the back of the TV for signs of damage and broken connections to inspect for broken backlights.

4. Remove Power Saving And Sleep Timer Option

If the backlights appear to be fine, then the next step is to remove any power saving and sleep timer options. This is important because these settings can cause your TV to turn off while still appearing to be on. To do this, go into the settings menu and disable any power saving and sleep timer options. 

5. Check for Failure In The Power Board

You should check for any failure in the power board. This can be done by taking off the back of the TV and inspecting the power board. If you find that there is a failure, then you may need to replace the power board before your TV will work again. 

6. Check The Settings

If the connections are secure, the next step is to check the TV’s settings. Ensure the input source is set to the correct one, such as “HDMI” or “Cable.” Also, make sure the volume is turned up and that the mute button is not engaged.

7. Contact TV Repair Professionals

If you've done quick repairs, but they don't work, it may be time to contact a TV repair professional. TV repair professionals are experienced in troubleshooting and repairing televisions of all types and sizes. They can identify the cause of the problem and provide the best solution for your TV.

When it comes to television repair, it is crucial to choose a qualified professional. Look for someone who has experience in repairing the type of TV you own and who is familiar with its latest technology. It is also essential to check the professional’s credentials and ask for references.

These are simple steps you can take when your TV turns on but no picture or sound is coming out. While other actions may fix this issue, these quick solutions should help you identify and resolve the problem.
