My first guess was that there is something wrong with the cable service, so I decided to change the channel.
The issue persisted, and I had no idea how to go about it. Hence, I decided to look for possible solutions online.
I was surprised to see how common this issue is and there are several underlying causes for a black screen on Toshiba TV.
To fix the Toshiba TV black screen, check for any loose cable and see if the power supply board is working. In addition to this, try disconnecting all the third-party devices and performing a power cycle on the TV.
In addition to these, I have also mentioned other troubleshooting methods like replacing the HDMI, turning the power saver mode off, and disabling the sleep timer.
Reasons For A Toshiba TV Black Screen
Unfortunately! There is no one reason for a Toshiba TV’s black screen. It can be a result of anything from a bad source to a motherboard issue.
Some of the most common reasons that can lead to a black screen in Toshiba TV are:
- If you are using a dish TV, there is a chance that the source went black. Try changing the source to rule out this reason.
- Faulty or loose cables.
- If the power-saving mode is on, it can turn the screen off if the TV is not used for several minutes.
- If the power source is faulty, it can cause black screen issues.
- Hardware issues like motherboard malfunction can also cause a black screen.
Check For Any Loose Cables
Before jumping to the conclusion that your TV has been rendered useless, inspect for any loose, damaged, or frayed cables and wires.
These are one of the most common reasons for a black screen in any TV.
Hence, it is imperative that you check all the audio and video connections and ensure that the cables are fixed in the ports.
In addition to this, if you are using a streaming device like the Amazon Firestick or the Mi Stick, make sure the connection is not loose.
Replace The HDMI Cable
If none of the connections are loose and all the cables are in the right shape, the HDMI cable connected to the TV might be faulty.
Even if there are no physical signs of wear and tear, replace the HDMI cable. If you don’t have another HDMI cable, use the cable from your Toshiba TV with another TV.
If it works then a faulty HDMI cable is not causing the issue.
Disconnect All The Third-Party Devices
Before moving on to other troubleshooting methods, remove all the third-party devices connected to the TV.
Some of the connected devices can hinder the functionality of the TV. To ensure this is not the case, disconnect all the devices and restart the TV.
Check The Power Supply
Another common issue that leads to a black screen is an issue with the power supply.
This issue can be with the power supply board, the power adapter, the power adaptor port, or the supply source.
The first step to ruling out any power supply issues is changing the power source. In addition to this, clean the power adaptor port.
While cleaning, just use a dry microfiber cloth. Don’t use any cleaning liquids.
If that doesn’t fix the issue, replace the power adaptor. You can use any universal power adaptor with the TV.
Perform A Power Cycle
Electronic devices are a combination of complicated systems that can malfunction even due to small glitches.
In most cases, these glitches can be fixed by simply power cycling the device.
If you have not been able to fix the issue with the solutions mentioned above, try performing a power cycle on the TV.
All you have to do is unplug the TV from the power source and wait for 2 minutes. After this, plug the device back in and turn it on.
Turn The Power Saver Mode Off
If you have turned on the power mode on your TV, know that the screen will go black just after a couple of minutes of inactivity.
If the black screen is temporary and you can still access the menu on the TV, turn the power saver mode off.
Follow these steps:
- Go to the menu.
- Select power and scroll to the ‘Power Saver/Echo’ option.
- Disable the mode and restart the TV.
Turn Off The Sleep Timer
Another reason for a black screen on Toshiba TV can be because of the sleep timer.
If you have set a sleep timer on your TV, it will shut down at the set time until you turn it off.
To turn off the sleep timer, follow these steps:
- Go to the menu.
- Select power and scroll to the ‘Sleep Timer’ option.
- Disable the mode and restart the TV.
Reset Your TV
If nothing else works, you might have to reset your TV.
For this, the screen will have to be not blank and this will only work if the screen is flickering or if the black screen comes and goes.
Follow these steps:
- Open the menu and go to settings.
- Select setup and click on ‘Reset TV.’
- Wait for the process to complete.
Contact Support
If you are unable to access TV settings and cannot fix the issue on your own, it is best to contact customer support. The team will be able to guide you in a better way.
Conclusion
TV issues can be quite frustrating especially if you don’t know what is causing them.
If your Toshiba TV screen is flickering and the screen is not completely black, this suggests that there is an issue with the source.
However, if the source is fine then it is most likely a hardware issue. If it was an issue with the power adaptor, the screen would have been completely blank.
In such a case, it is ideal to contact a professional.
