If your Toshiba TV is no longer working properly, there are several different problems you may have. You can try to reset your TV or replace the backlight or T-CON board. If those don’t work, you may have to reseat the video and audio input connectors. You can also use a soft reset or check for loose cables.
Replace the backlight
There are some common causes for backlight failures on LCD TVs. These include water damage, drop damage, and defective components. These types of problems can be resolved quickly by following some basic steps.
First, unplug the TV. If the black screen remains after plugging it in, your TV is probably running off of a bad power supply board.
Next, disconnect the backlight cable. You will need to unplug the cable from the two circular metallic points on the rear of the TV. You can do this with a suction cup or painter’s tape. If you can’t do this, you may need to take your TV to a TV repair shop.
Third, check for loose connections. You can also check for a bad HDMI cable.
Re-seat the video and audio input connectors
If you have a Toshiba TV with no sound, there are several things you can try to fix it. One of them is to re-seat the video and audio input connectors. However, this can be a daunting task. If you are unsure of how to do this, you can contact technical support for assistance.
Another thing to do is to check your HDMI port. You can do this by plugging an optical audio cable into a different HDMI port. If it works, you may want to try switching the port.
If you are still having trouble, you can try a more drastic measure. If your Toshiba TV has a power supply board, you may need to replace it. You should also check for a loose video and audio input cable. These can cause signal loss and a blank screen.
Check for a loose cable
Depending on your Toshiba TV model, you may be able to solve a black screen problem by simply checking the HDMI cable connection. If this does not help, you may want to contact a technician to help you with the problem. The problem might be caused by a faulty component, a loose cable, or a faulty connection.
Before you try any of these tips, however, you will need to check the input and power supply. If your TV is having an issue with the power supply, you might need to replace the power adaptor. The power adaptor will be located on the back of your TV. You should remove the power cord from the back of the TV and wait for at least 30 seconds before plugging it in again.
Replace the T-CON board
If you have a Toshiba TV and you’re experiencing any kind of video or picture problems, you may have a problem with the T-CON board. This board is the smallest electronic component in a LCD television. It converts signals from the main board into image on the screen.
The T-CON board is located in the back of your TV, behind the main circuit board. It is also known as the timing controller. It is the most important part of the display module of your TV.
If you have a T-Con board that is malfunctioning, you can get rid of this issue by replacing it. However, before you go to the store, you should first troubleshoot the TV.
To begin, you must remove the rear panel of the TV. You can do this using a flathead screwdriver. Once the panel is off, you will need to flip the TV over. You’ll then be able to see all of the electronic components.
If your Toshiba TV screen suddenly turns black with no picture, or if you cannot navigate the menu, then you may want to try a soft reset. This will clear out any internal Toshiba TV settings and will bring your television back to the original factory defaults. It also lets you reset your Wi-Fi connection and get a fresh start with your TV.
To perform a soft reset, you must first unplug your TV from the wall and wait a few seconds before plugging it back in. If you do not want to wait, you can remove the power cord from the back of the TV. This will discharge the electricity but will clear the memory of your TV.
Depending on your particular model, you may have to do a factory reset to fix these issues. If you have a Smart TV with WiFi, you will also need to enter a PIN code into your television to confirm the reset. This process will clear out all the personal data and apps you have installed on your television.
