Understanding the Issue: Sound but No Picture

Before focusing on ways to solve the issue, let’s try to analyze the reason as to why you can hear sound from the television but cannot see any picture. 

The modern home entertainment system is based on A/V signals, and HDMI is the main A/V output interface of streaming boxes, game consoles, or Blu-ray players wired to the screens. 

When things go wrong, several issues could have caused it:

1. Faulty HDMI Cable

When HDMI is poorly connected, frayed, or damaged it may prevent the video signal from reaching the display but allow audio. 

At times, it could appear to work properly with audio but not with video.

2. Input Source Mismatch

In some cases, a user may set the wrong input source on the television, for example: the device is plugged into HDMI 1 and turned to HDMI 2. 

The audio will be available while the picture will be absent.

3. Device Compatibility Issues

You rarely see devices that perform the same purpose and functions; they come in different shapes and sizes. 

Which can sometimes lead to compatibility problems. This especially happens when ancient electronics are being used with newer televisions.

4. TV Settings Malfunction

On some occasions, the problem could be with the TV settings. Some picture settings may be disabled or not adjusted correctly, which causes a black screen picture.

5. Software Glitches

Communication failure can also be experienced due to a firmware or software issue with the TV or connected device, thus producing audio with no picture.

6. Defective HDMI Port

The broken HDMI port of the television or the connected device can also create problems. 

In case the port is damaged or physically dirty with dust and particles, the connection may not work properly.

7. External Interference

There are also other reasons which include electrical interference or other appliances that are connected can also be the causes for the issue.

Step 5: Address Software Glitches

In case any spellbound or abnormal behavior is witnessed from the television or a peripheral device, it may be suspected that a software defect is present.

Power Cycle: 

Switch off the power supply to the television and the connected device for a minute and then restore the same supply after waiting for one minute. 

Turn on the power supply afterward.

Factory Reset: 

Factory resetting a device is the last option one may want to resort to. This action deletes every other setting along with personal data.

Step 6: Inspect HDMI Ports

In extreme circumstances, let’s say a broken HDMI port, the situation is made worse by a poorly built interface.

Physical Inspection: 

Check to see if any of the pins are bent or if there is any debris lodged inside the port which could affect the contacts.

Cleaning: 

Using a spray can carefully wipe the HDMI connectors to eliminate the dust or debris that has settled.

Step 7: Minimize External Interference

Finally, external interference may also be impacting your setup.

Check Other Devices: 

When troubleshooting a problem, disconnect any other devices that may be connected to your TV or the HDMI device. 

At times, another device may be the cause of the snooze.

Power Supply: 

Make sure you plug the devices into a surge protector to reduce the effects of electrical interference.
