Kogan TV no picture but sound? Well, this is a common problem that many users experience!
If you only hear sound on your Kogan TV, but the picture is missing, it is a good sign because it shows your TV is working.
The TV picture could be missing due to numerous factors, and in this guide, we’ll unwrap them all at your disposal and help you bring back the TV image in minutes.
When the Kogan TV picture is missing, but the sound is there, start via power circulation and switch the input port/source. If this doesn’t help, test with a different video transfer cable and inspect the TV’s backlight.
Let’s unwrap how all of this can be done in under 5 minutes!
How to Fix When Kogan TV No Picture But Sound?
Tip: Follow the steps chronologically!
1. Test Your TV Without an Input
The first step is very simple! Unplug everything from your Kogan TV and check whether the picture of the television will work when there is nothing connected.
In most cases, the reason why you’re only hearing the audio is due to a buggy external device, which fails to transfer the picture to your Kogan TV.
So, if your TV picture is back when you unplug your externally connected devices, this shows that the issue is not with your TV thus, jump to step #5.
However, if your TV screen is still black, even without any video devices connected, continue reading the next solution…
2. Plug Out and In Your Kogan TV
A very simple yet effective solution is to disconnect and reconnect your Kogan TV from the power outlet, which will apply a power circulation.
This method is safe, it won’t erase the data from your TV, only discharge the power, reboot the operating system, and provide a fresh start.
Here are the steps to apply a proper TV power circulation:
- Using the remote control, turn OFF your Kogan TV.
- Then, disconnect the power adapter from the outlet.
- Also, unplug the A/C cable’s connector from the port.
- Wait for 60 seconds for your Kogan TV to discharge.
- Connect the TV to power and press the Power button.
Tip: You can apply power circulation whenever you face issues with your Kogan TV.
3. Wake Up the Kogan Television
The reason why your Kogan TV picture is missing but the sound is there could be because the TV is sleeping.
If you didn’t know, Kogan TVs are equipped with an adjustable sleep timer, and after a certain amount of time, your TV will go into “Standby Mode,” turning off the display.
To wake up your Kogan TV quickly, take the remote control and press on the “Sleep” button, located at the top-right.
You only need to press the button once to wake up your Kogan TV and check whether the sleep timer is causing the problem.
Note: You can set the Kogan TV sleep timer to 10min, 20min, 30min, 60min, 90min, 120min, 180 min, 240min, or entirely cancel the feature.
4. Switch the TV’s Picture Source
The reason why you hear sound but the picture is missing on your Kogan TV could be due to a wrongly selected picture input source.
If you have a source device connected to one of the video input sources on the TV, you need to make sure that you’re viewing the correct source.
For instance, when a third-party device is connected to the TV’s HDMI1, but you’ve selected the HDMI2 input source, the TV screen will be black.
The audio that you’re hearing could be from the connected device, so it’s important to switch to the correct TV source, where there is an input device connected.
Here’s how to switch to another TV source on Kogan TV:
- Verify that your remote control is functional.
- Press the “Source” button from the left side.
- Select the TV source with an input device.
- Use the arrows to select a different source.
Note: Your Kogan TV supports HDMI, Component, ATV, DTV, Media, AV1, AV2 and PC, so select the correct source as per your connected device.
5. Use a Different Video Input Port
When you have a video device connected to your Kogan TV, the input port that you’ve used could be causing the picture to disappear.
This happens mainly when a single HDMI port has been used for a long time, and the socket no longer holds the cable connector tightly/securely.
This is why we recommend switching to another (same) video transfer port and checking if the picture from your externally connected device will re-appear.
Typically, Kogan TV has 3 HDMI ports, one suited on the side and two more located on the back panel near the other input ports.
Reminder: When switching the video cable connector to a different TV port, you must also switch to another TV input source, as explained in the previous step.
6. Replace the Video Transfer Cable
When you’re using an HDMI video cable to deliver pictures from another device to your Kogan TV, know that this cable handles both audio and video.
So, you may only be hearing the audio but don’t see the video because the video transfer cable is faulty, loose, ripped, or defective.
Before replacing the cable, however, we strongly recommend checking out the first step from this guide.
There, you will verify that the TV screen works without input, which leaves only the video transfer cable as a suspected culprit.
Choosing an HDMI Cable:
Another reason why you only hear sound but the picture is missing could be due to the long length of the HDMI cable.
To transfer a 4K picture to the Kogan TV, you need as short a cable as possible, with a maximum of 10 feet, so bear this in mind when purchasing a new cable.
7. Adjust Source Device Resolution
Sometimes, Kogan TV sound but no picture issues arise when the resolution of a connected computer does not align well with your TV resolution.
This causes the sound to go through, but the video does not work due to software resolution incompatibility.
If your connected device has the option to manually switch the resolution, go ahead and match the device’s resolution with your Kogan TV’s resolution.
Here are the different TV resolutions that you may need to select:
- 4K – 3840 x 2160 pixel
- 2K – 2048 x 1080 pixel
- HD – 1920 x 1080 pixel
- SD – 720 x 480 pixel
Switching the resolution on your connection device should bring up the picture on your Kogan TV instantly and resolve the problem.
If this doesn’t work, try rebooting the source device or at least checking with another video transfer device such as a console, computer, or video player.
If your TV picture is missing, regardless of what you do, the screen may likely be malfunctioning, so continue reading to reveal more…
8. Inspect Your Kogan TV Backlight
If nothing helped, it’s possible that your Kogan TV’s backlight is not working, which is why you hear the sound, but the picture is missing.
So, we’ve prepared a quick step that will help you find out whether that’s true and whether your TV needs servicing.
Here’s how to test the backlight on your Kogan TV in easy steps:
- Verify that the Kogan TV is turned on and working.
- Turn off the lights (must be as dark as possible).
- Take a flashlight (you can use a phone’s flashlight).
- Point the light towards the TV from a proximity.
- Move the flashlight around to see if there’s a picture.
If you can see a silhouette, then your TV screen backlight is not working, which is causing the black screen but does not interfere with the audio.
So, in those cases, it’s best to check your warranty or bring your TV for servicing.
Note: If you see absolutely no picture, even with your flashlight, then something with the display of the TV is not working.
Hence, when Kogan TV has no picture but sound, test the TV by unplugging all video inputs and performing a power cycle.
Also, switch to a different video source/TV port, adjust the source’s resolution, and inspect the TV’s backlight.
