Toshiba TV Not Working

It can be a frustrating experience when your Toshiba TV is no longer working. Follow along as we show you how to fix it quickly and easily.

If your Toshiba TV is not working, first, check the power connection to ensure it’s plugged in securely. Next, try a power reset by unplugging the TV for a minute, then plug it back in. Press and hold the power button on the TV for 15 seconds. Finally, check if the issue resolves.

As you can imagine, there are many different factors that could influence how a TV is working. In some cases, it may be a specific problem that needs to be corrected.

Toshiba TV Not Working

A soft reset will often correct the problems with your Toshiba TV. It tends to correct issues associated with everything from pairing with other devices to strange fluctuations in the volume.

At times, however, you may need to go beyond resetting the television because there is a power problem associated with it. This is something that can be corrected on numerous levels, but try the following in order to see if you can get it working again.

Breaker box

If the breaker has tripped in the breaker panel, you need to reset it. A tripped breaker will be slightly out of line with the other breakers and may have some red showing.

Reset the breaker by flipping it to the off position and then turning it back on again. You may need to do it twice in some cases.

If the breaker continues to trip, it is something that needs to be addressed. It may or may not be the Toshiba TV that is causing the problem, although it is likely one of the biggest power drains in the circuit.

You can check the breaker and wiring by unplugging all of the devices that are connected to that circuit. If the breaker continues to trip, it is a problem with either the breaker or the wiring. Contact an electrician. The same is also true if you see any smoke or smell a rotten egg smell from the breaker panel.

It is also possible to determine what is causing the breaker to trip if it is an external device. Plug each of the devices in one at a time and power them on. If the breaker trips, the device needs repaired or replaced.

Power strip

Although power strips can be convenient, they can also cause some problems. Most of us tend to overload the power strip with far too many devices.

The power strip can also fail, and it may only be one of the plugs that are experiencing the problem. In order to fix this issue, you can buy a heavy-duty strip or plug things directly into the receptacle.

You can also check the power of the TV by bypassing the power strip and plugging it into the receptacle.

Check the Receptacle

Plug another appliance or perhaps a lamp to check the receptacle. If it is not working and the breaker has not tripped, the receptacle needs replaced.

Inspect the Power Cables

If the power cable has become damaged, it must be replaced. Visually inspect the power cable, including the plug, which may be burnt.

Check the Cables

You may also be experiencing problems with your Toshiba TV because of the cables that are plugged into it. Unplug all cables except the one you are using and see if it corrects the problem.

HDMI and other cables do go bad from time to time. They may also need to be upgraded to the newest type.

If, after inspecting the cables, you determine that one of them is bad, replace it. You can also swap out cables with each other to test them.

Remote Control

One other thing to check is the remote control. If the batteries have died or if it is malfunctioning, the TV may not operate.

Try using the buttons on the Toshiba TV directly and see if that allows the TV to turn on and for the functions to begin working.

Toshiba TV Not Connecting to WiFi/Internet

Internet problems can be difficult to diagnose but there are some things you can do to fix the issue without too much hassle.

The first thing we would recommend is to test the Internet using another device. This could be any Wi-Fi-capable device, including a phone or a laptop.

If the Wi-Fi is working, the television may be too far away from the router. Although new routers do a good job of directing the Wi-Fi where it is needed, the signal will get weaker as you get further away from the source.

If there are any objects in the way or if too many devices are connecting, this can also reduce the amount of bandwidth available for the Toshiba TV. Operating the TV at a busy time of the day when many people in the neighborhood are connecting to the Internet can also be problematic.

You can check the Internet connection by plugging the television directly into the router with an ethernet cable. It will let you know if it is an issue with the Internet or an issue with Wi-Fi.

If you are still not able to connect to Wi-Fi or the Internet, you can start resetting devices. The first to try is resetting the router.

Unplug the router and disconnect all cables. Wait 60 seconds before reconnecting the power. It may take a few minutes for the router to fully boot up.

You can also perform a soft reset of the Toshiba TV. Hold down the power button for 10 seconds or disconnect the power altogether by unplugging the TV for 60 seconds.

A factory reset is the last option because it will erase any custom settings. You can reset the Toshiba TV by using the home button on the remote and navigating to settings. You will see the option to reset to factory default under the ‘device & software’ setting.

Toshiba TV Not Detecting/Connecting HDMI

Almost everything you operate on your Toshiba TV will connect using an HDMI cable. Here are some ways to determine why it may not be connecting using the cable.

Outdated HDMI

Like any type of technology, HDMI cables have been upgraded over the years. If you are using an older HDMI cable, you may need to upgrade to a new cable.

Damaged HDMI Cable

Visually inspect the cable for any obvious damage. You can also use another HDMI cable to test the other cable and make sure it is working properly.

Try Another Device

If one device is having difficulty connecting to the TV, you can try another device to see if it works properly. Unplug the device from HDMI and plug in the new device to see if it is operating.

Check the Settings

Some devices may be incompatible with certain settings on the TV. Checking and adjusting the video output settings may help.

If possible, you can also force the device to run at a lower resolution. This may help to correct the issue.

Toshiba TV Not Finding Channels

Generally speaking, a problem with a Toshiba TV not finding channels is likely to be associated with an antenna but it can sometimes be associated with cable or satellite. Here are some ways to check and fix the issue.

Channel Blocking

Newer Toshiba TVs offer the ability to block channels. Some of the channels may have been blocked inadvertently and if that is the case, your Toshiba TV will not find them when looking for new channels.

TV Source

Go into the TV settings and check both the input and source. If you are trying to add new channels from a cable box or satellite box, you will have to have the settings correctly set before new channels can be found.

Start from Scratch

If all else fails, delete all channels from the TV and start fresh. Go into autotune through the settings using the remote control and have the TV look for new channels again.

Toshiba TV Not Turning on Flashing Red Light

A flashing red light on your TV is typically a source of frustration. Rightfully so, because it often results from a problem with the TV that is difficult to fix.

In some cases, the flashing light and the fact that the TV is not turning on means that it will have to be serviced by a technician. It may have been a problem with a power surge that fried some of the components.

Before you contact customer support, check the timing of the blinking red light as well as the number of blinks happening in succession. Giving them this information may help to diagnose the problem.

Aside from a power surge, you might also have a blinking red light if you are not getting enough voltage. You may have too many items plugged into the power strip so bypass the strip and plug the TV directly into a receptacle.

One other thing to try is a long reset. Unplug the TV and leave it unplugged for an hour. Hold in the power button on the TV while plugging it in and continue to hold it in for a minute. This may reset the TV and start it working again.

Toshiba TV Not Turning on No Red Light

If there is no red light and the TV is not turning on, it could be a problem with the power. Check the following:


Check the breaker box for a tripped breaker. Reset the breaker by turning it off and back on again.


Plug the television directly into the receptacle and see if it starts. Test the receptacle if it is not working by plugging in a lamp or another electronic device.

Visually inspect the power cords and replace them if they have been damaged.

Try a Soft Reset

Reset the device by unplugging it and waiting 60 seconds before plugging it back in again. This may fix the issue.

Finally, try using the buttons directly on the TV and not on the remote. This is something that is often overlooked by people who are having difficulties with their television.

When a Toshiba TV is not working, it needs a soft reset. Unplug the TV, wait 30 seconds, and plug it back in. This will often help the TV to respond and refresh the settings automatically.
