Toshiba TV Won’t Turn On (You Should Try This Fix FIRST)

For some reason most Toshiba TVs eventually run into a similar problem of simply not turning on.

There are countless cases of Toshiba TV owners who say they’ve had this problem – some say it’s been an issue they’ve dealt with for multiple years!

Luckily there is a very easy fix that should resolve about 80% or so of Toshiba TVs that won’t turn on.

Toshiba TV won’t turn on

If your Toshiba TV won’t turn on you need to reset it. Unplug your TV and wait a full 60 seconds. While the TV is unplugged, press and hold the power button for 30 seconds. After the 60 seconds are up, plug your Toshiba TV back in and it should work.

Unplug Toshiba TV from wall

While this fix sounds obvious, unplugging your Toshiba TV from the wall socket is the most common way to get it to turn back on.

The key here is to actually wait the FULL 60 seconds. Have a little bit of patience and make sure it’s been at least a minute before plugging it back in.

While the TV is unplugged, find and hold the power button on your Toshiba TV for 30 seconds. Make sure you are holding the power button on your TV, and not your remote.

This will help to drain any residual power left in the TV and allows the TV to soft reset itself. This is different than simply switching the remote on and off!

(If you can’t find a power button on your Toshiba TV, simply skip that step)

Once you plug the TV back in after the 60 seconds, you should see it power back up no problem.

While this fix should work for about 80% of cases, the remaining 20% can be a bit trickier. If you’re still having trouble getting your Toshiba TV to turn back on try the fixes detailed below.

Remove batteries from Toshiba remote

If unplugging and re-plugging your TV in didn’t fix the problem, try taking the batteries out of your remote.

Make sure to take both batteries completely out of the remote.

Remove batteries from remote

With the batteries removed proceed to hold down the power button on the remote for 30 seconds. Again, do this for a full 30 seconds! Not 10 seconds, 30!

After the full 30 seconds are up, put the batteries back in the remote and try to turn on the TV. It should power back on.

You might want to consider putting in a new set of batteries during this step just to be sure!

If either of the two steps above fix your Toshiba TV power problem but then a few days or weeks later you run into the same issue, you’ll want to try factory resetting your TV for a more permanent solution.

Factory reset Toshiba TV

With the TV powered on (hopefully unplugging it or removing the remote batteries was able to temporarily power the TV) click the Home button on your remote.

Then go to Settings > Device & Software > Reset to Factory Defaults. Your TV will turn off and on again and then display the initial setup screen.

This will essentially restore your Toshiba TV to the settings it had on the day you purchased the television.

If you have an older Toshiba TV, the factory reset steps may differ slightly from what’s above. Try one of the following:

  • Menu Button > Settings > Setup > Reset TV
  • Setup Button > Installation > Reset tV

Factory reset Toshiba TV without remote

If for whatever reason you do not have access to your TV’s remote, you can still factory reset your Toshiba TV.

To do this, find the small Power/Input button on the back of your TV. Depending on the model you have this may be on the right hand side, left hand side, or very bottom of the device.

Unplug your TV and then start pressing and holding that button for 10-15 seconds. As your holding this button, go ahead and plug your TV back in. Keep holding the button down until you see the Toshiba logo appear on the TV. When you do, you can stop pressing the rest button.

Eventually your TV screen will show a few options. Scroll down to “wipe data/factory reset”. To toggle to this option simply keep tapping the Power/Input button until you land on it. To select this option, press and hold the Power/Input button.

Keep in mind that after your Toshiba TV reboots, you’ll beed to re-pair your remote. To do so simply press and hold the home button on your remote for 15 seconds and then wait a minute.

If you’re having trouble finding this button on your TV, or if your TV is mounted in a tight spot, there are other options.

First, consider plugging in a USB keyboard directly into the back of your Toshiba TV.

You can then use the keyboard to navigate and reset your TV.

Another option, if you have a Toshiba Fire TV, is to download the the Amazon Fire TV app to your smart phone.

After connecting your TV to the app, you can use your smart phone as a remote!

A final possibility is to grab a universal remote you have lying around and enter the appropriate Toshiba code for the remote to get it working.

At this point you should have fully resolved your power issues but just in case you haven’t I’ve included some additional steps worth trying before calling it quits.

Reseat power cord in back of Toshiba TV

Another pretty easy potential fix to your power problem is to unplug the power cord from the back of the TV.

Leave this unplugged for 60 seconds or so and then plug it back in.

When you plug it back in make sure that the connection is snug! You don’t want this to be loose at all – a tight connection is important to ensure the TV is getting stable power.

With the power cord plugged back in, power on the TV using the TV power button, not the remote!

Hopefully you see the TV come back to life.

Select the Correct Input Source

Your Toshiba TV might appear to not turn on because of an incorrect input source. You have to choose the proper input source for your TV to work correctly.

So whether you’re using a streaming device, DVD player, or a cable box, double check that your TV source/input matches the number HDMI port being used. In the example below, you’d turn the TV to “HDMI 2”.

Select the Correct Input Source

You can select the correct input source using two different methods:

Method 1 – Enable Input Source using a Remote Control

  1. Turn on your TV
  2. Press the Source button on your remote control
  3. Select the desired input mode

Method 2 – Change Input Source without Remote Control

  1. Turn on your TV
  2. Press the MENU button on the side or bottom of the TV
  3. Use the volume button to navigate to the source option
  4. Press the menu button to select the desired input source

Note: Some TVs have a source button at the back or side that you can use to select your preferred input source

Try a different power outlet

While unlikely the cause, if you’re still having no luck up until this point then I would try plugging your Toshiba TV into a different power outlet in your home.

Sometimes outlets have a short or a blown fuse and we just don’t know it.

Alternatively, if you don’t want to lug your TV around, you could simply grab another smaller appliance and plug it into the outlet you’re trying to use for your TV.

If you see that device power on then you know that particular outlet is working and that’s probably not your issue.

Again, this is likely not the cause but a worthwhile troubleshooting step that should be quick to eliminate as a suspect.

Backlight is broken

If nothing has worked to this point it is very possible that the backlight of your Toshiba TV is broken.

An easy way to determine whether or not this is the case is to power on your TV and then take a flashlight and bring it very close to your TV screen.

Look very closely to see if there is any image on the screen when you flash the light.

If you see a picture appearing, but it’s extremely faint, it’s probably because the backlight of your TV failed and it needs to be replaced.

Power supply replacement

If nothing has worked to this point, but you really want to keep your TV, you can try removing the TV’s power supply and sending it in for repair.

Before you do, check to see if your TV’s stand-by light is on. If it is, this means your power supply board is probably working and it doesn’t need a full replacement.

In this case, you should consider testing the voltage across various points of your power board. If you get irregular voltage readings, the problem is likely with the voltage regulator!

Voltage regulator failures are extremely common with Toshiba TVs!

Note: if your voltage regulator is in fact broken, you’ll likely have to replace the corresponding fuse as well.

I’ve included a nice tutorial on how to replace the voltage regulator and fuse below.

If you have no power and no standby light, this likely means your power board is in fact defective, or dead. This could easily be caused by a power surge.

Many TVs are known for faulty/weak power supplies, but the good news is they only cost about ~65 bucks or so to repair (if you’re willing to do the work of removing it from the TV yourself).

Keep in mind this process is a bit time consuming as you’ll need to remove every single screw on the back of the TV to get the casing off and ultimately the power supply.

It’s also a bit risky of a step because this may not necessarily be what’s causing your power issues!

Contact Toshiba support

If you still can’t get your Toshiba TV to turn on, you can try contacting the Toshiba support team.
