Toshiba TV Won’t Turn On : Quick Fixes Inside

Toshiba has been a mainstay in consumer electronics for a long time and has a formidable presence in the market. Anyone who knows me knows Samsung is one of my favorite TV manufacturers currently. However, if any company were to hold a candle to Samsung’s smart LED lineup, it would be Toshiba, particularly its Fire TV lineup.

Sometime ago, I wrote about common fixes for Toshiba lines on screen. I’ll be doing something similar this time. Have you ever called in sick to tune in to your favorite show in the morning, but your Toshiba TV won’t turn on? Nothing ruins the day quicker than a broken TV set. 

Whether your Toshiba TV is running on Amazon’s Fire OS or Android 9.0, all operating systems can become riddled with annoyances like bugs and glitches. One such problem rears its ugly head in the form of your TV set’s complete disobedience to turn on, but don’t worry. I’ve personally scoured the internet for Toshiba TV troubleshooting tips and tried them out on my set to verify their efficiency.

If your Toshiba TV won’t turn on, the first thing to do is check for hardware and cable damage. Then, you can check for a software update in case the OS is riddled with bugs. Alternatively, you can perform a power cycle for the remote and TV. You can try booting the system to the latest firmware. If all else fails, there’s always the trusty factory reset option.

Today, I will explain in detail what you can do if your Toshiba TV won’t turn on, expanding on the above mentioned solutions.

Toshiba TV Won’t Turn On Solutions

Fix 01: Cable and Hardware Inspection

If you’ve run into this dreaded situation, the first thing you’re bound to think is, “why is my Toshiba TV not turning on?” The first thing to do is inspect the hardware and cables. These are your television set’s lifelines and ensure the proper functioning of electronic devices. They need to be in pristine condition to continue functioning optimally. 

First, ensure the cables are plugged into the designated ports properly. You can refer to the user manual to verify which cable goes into which port, even if you’re sure of the connections. Carefully inspect the HDMI cable, ensuring it’s plugged in properly and not showing any loose movements near the port. 

Since cable design follows a TV’s specifications, using third-party cables can spell trouble for your device if the specifications don’t match or there are compatibility issues. Therefore, always ensure you’re using the cables Toshiba provides, and contact their customer service department to replace worn-out ones. 

If the cables aren’t the source of your misery, move on to the hardware. Although TVs typically last several years without suffering from hardware failure, component degradation is inevitable. Your Toshiba TV won’t power on if its internal components are damaged and causing issues with the device’s system. 

Hardware issues are particularly persistent in smart TV sets like the Toshiba Fire TV. If you’re facing Toshiba Fire TV not turning on issues, move the device to a well-ventilated room and keep the hardware free from dust and liquids. Thermal throttling chances in these TV sets are high due to the added smart components and since dust settles inside the device over time. This can cause the television to heat up, triggering the safety mechanism that shuts it down till the device naturally cools down.

Thermal throttling happens when the chip that controls the various functions of your TV gets too hot to function. To prevent long-term damage to the CPU, the system draws back on some of its power to help the chip cool down. This ensures that the chip does not overheat.

However, if the chip gets too hot to even operate, the system will not turn on, and this could be one of the reasons your Toshiba TV won’t turn on. This is basically a built-in safety mechanism, as the chip can cause a fire or can even explode if it gets too hot.

In such situations, wait things out and let the TV do its thing. Clean the ports and identify the cause of hardware issues that might have contributed to thermal throttling, and wait until your television set can be booted back safely – this usually takes a few minutes. 

Furthermore, port inspection is essential as these feeble parts can easily be damaged from mishandling cables and cords. Damaged ports tend to hamper the proper functioning of appliances, so it’s best to contact customer support to request replacements.

Fix 02: Performing a Power Cycle

So, you’ve tried Fix 01, and your TV set isn’t functioning correctly. Then it’s time to perform a power cycle on your device and its remote control. A power cycle is like a software reboot for TV hardware. It resets the charge of electric circuits inside the TV’s internal components and refreshes the hardware. 

A software reboot won’t be possible if your Toshiba Fire TV won’t turn on, and a power cycle might be the only way to reboot the system for further inspection. 

Follow these steps to perform a power cycle on your television set:

  1. Unplug the TV.
  2. Long press any buttons on the TV set for at least 10 seconds to discharge the remaining current.
  3. Let the TV sit idle for a minute after unplugging.
  4. Plug the set back into the socket.
  5. Wait for 1 minute before switching the TV back on.

You can also repeat the process on your television’s remote control. This is done to ensure the controller is reset and continues proper signal transmission to the TV. Follow these steps to perform a power cycle for the remote controller:

  1. Remove the batteries from the remote.
  2. Inspect the batteries and replace them if necessary.
  3. Wait 1 minute, and press and hold the remote buttons to dispel any remaining charge from the device.
  4. Put the batteries back in the remote.
  5. Wait for 1 minute again before using the controller.

Fix 03: Updating the Software

One of the biggest reasons for your Toshiba TV not turning on might be software issues, especially if the above fixes fail to work out. If these solutions failed to boot up your device even once, you’re better off contacting a certified technician for thorough inspection and repairs. 

Although Toshiba and third-party software providers regularly roll out patches and software updates to resolve issues, people tend to skip software updates entirely. Most of these people ask “why my Toshiba TV won’t turn on,” yet they still keep using the same software version from years ago.

You can’t update the software if your Toshiba Fire TV won’t turn on. Therefore, it’s essential to constantly keep your television set updated with the latest software patch since it helps prevent glitches, app crashes, and even sound problems.

If you’ve managed to boot the device at least once using the above fixes, here’s what you need to do to update the software:

  1. Navigate to the TV settings option from the main menu.
  2. Tap on the Device and Software section in the settings.
  3. Find the About option and click on it.
  4. Tap the Software Version icon and wait.
  5. A pop-up or new window will appear with a set of options.
  6. Tap on the Check for System Update option.
  7. If there’s a prompt for a new update, click on the install button.

Installing the new update might help resolve future issues with your Toshiba TV.

Fix 04: Factory Reset

Doing a factory reset is one of the best Toshiba TV troubleshooting tips to help solve your issue. If your Toshiba TV turns on then off, you can at least attempt this final fix before contacting a professional for repairs. 

A factory reset is a complete reset of your TV set and involves cleaning all user data, so you end up with the device in its original condition, like when you first purchased it. However, if your Toshiba Fire TV won’t turn on, you cannot attempt the solution, hence the requirement.

Follow these steps to attempt a factory reset:

  1. Navigate to the settings option in the main menu.
  2. Find and click on the Device and Software option.
  3. Tap the Reset to factory defaults icon.
  4. Choose the Reset option from the prompt.
  5. Press your remote’s Play/Pause button to initiate a factory reset.

Following these steps will bring your TV back to its original settings and give you time to identify any corrupted applications or services causing the issues. Sometimes, my Toshiba won’t turn on simply because of a bug triggered by a corrupted application. It’s best to avoid installing something like that until a permanent fix presents itself.


These were some of my attempted fixes for a Toshiba TV not turning on and have never failed to solve my personal device’s issues. A Toshiba Fire TV not turning on even with the four fixes I’ve mentioned warrants contacting the company’s customer services department for a thorough inspection of your device, and they’ll help fix your television set in no time! No more having to wonder, “why won’t my Toshiba TV turn on?”
