3) Wrongly Modified Settings

There may arise some error or unusual behavior offered by your Toshiba TV which is all due to your pre-selected settings and one of which is the Energy Saving Option.

Toshiba models are built to save energy and you will find multiple energy-saving features in your Smart Toshiba TV.

You can pick different options switch off, custom, medium, maximum, and auto which are according to the customization. These options perform various actions like if you have enabled auto mode, it will turn off your power depending on the lowest power consumption mode to save energy.

It will turn off your TV automatically because this action is due to the pre-made settings in the device.


Don’t ever set your Toshiba TV to ‘Auto mode’ as it doesn’t require your involvement to turn off the TV but it adjusts the controls automatically depending on the scenario.

If you have already enabled this setting, you can change it and set it to ‘Custom mode’ which tries to prevent your TV from turning off and on.

4) Sleep Timer Setting

One of the primary reasons why Toshiba TV turns off is due to its power settings. Because you have somehow made the power setting turn off after a few minutes.

There are different navigations according to the model of your Toshiba TV which could be found on your Remote and TV settings i.e.; Timer settings, Power Off, Standby Sleep Settings, etc.

If your TV keeps shutting off every few minutes, you should disable your TV’s unnecessary settings and adjust/turn off Timer, Standby Mode, and Sleep settings accordingly.

i) Your timer setting is enabled which automatically turns off your TV after some time. To turn off ‘Timer setting’ or ‘Auto Mode’ from your TV,

  • Go to the Menu option on your TV.
  • Then click on ‘Timer’
  • Press ‘On TImer’ & ‘Enable on Timer.’
  • Toggle this option off from the screen.
  • Exit.

ii) Standby option is enabled sometimes which allows the device to turn off automatically which can be turned off by following the steps mentioned below.

  • Go to Menu option and click ‘Power Management
  • Click on ‘Active Standby Mode’
  • Toggle off this option.
  • Exit.

  • Go to your TV main Menu.
  • Click on Power Management.
  • Now, press ‘No Signal Power Down.’
  • Select your Input and toggle it off.
  • Exit

5) Check for Updates on your Toshiba TV

There are obviously errors in the older models of Toshiba TVs and other electronic devices as well which is why their manufacturers have to bring out an update for the device to make it work smoothly without any errors or bugs.

When an electronic device like Television is launched by any Company or Brand, manufacturers usually give a bit of time to users to check their experience with the product.

Then, they start taking feedback from their users. Their motive behind the feedback is to check the device’s working experience, its compatibility, and other enhancements with different software working on the screen. So, they launch a new system update to rectify any bugs. 

Amazon also launches Over The Air (OTA) firmware updates to fix any bugs. 


  • First of all, open your Toshiba TV settings.
  • Now, head over to My Smart TV.
  • Tap on About.
  • Now, you can update your System Software.

6) No power to Electrical Wall Socket

We may run into a problem where we consider our device to be faulty but the problem is outside the product domain. The most basic problem in this regard is no power being supplied to an electrical wall socket.


Check that the electrical wall socket is receiving power. Confirm that the socket where the TV is plugged in is not controlled by a switch or timer or that the surge protector on a power strip is not tripped.

Plug a working lamp or another electrical device into the socket. If that device does not work, plug the TV’s power cord into a different socket and attempt to power up the TV.

7) REGZA-Link Signal Issue

This is a new feature that uses CEC (Consumer Electronic Control) Technology in Toshiba TV which enables the users to auto-control all their devices that are REGZA-LINK compatible through HDMI connection via remote control.

It allows you to control the multiple functions of your computer wirelessly, which may help you during your presentations and you don’t have to rush to your computer again and again.

But, you may get frustrated due to your TV/computer behaving misguided through a signal by another REGZA-Link device.


You may find this setting in your computer depending on the model you are using.

  • Go to your TV menu
  • Turn off the REGZA-Link signal.

8) Overheating in Toshiba TV

Electronic devices are meant to keep in a dry place where they are saved from any liquid or dust. Dust particles enter into the different electronic parts of TVs and thus they block the connection area.

Water is a big enemy of Electric current and hence electronic gadgets are designed to keep them safe from water and other liquid materials. But, when they are exposed to water, their electronic boards may catch the heat and thus be wasted.


Must clean your TV internally and externally as well and keep it away from dust particles. You can clean your TB by following the steps mentioned below.

Tip: You can use a Microfiber cloth to clean your TV.

  • First of all, you need to turn off the power of your TV.
  • Now, you may split the outer part of your TV.
  • Clean it with the help of a blower where it is impossible to reach and you can get the dustout.
  • You can clean the exterior part with the help of Fiber Cloth.
  • You must clean TV air vents with the help of spraying a can of compressed air. 

9) Remote may be Defective

You must check your Remote because it may be the cause which we may forget.

The Remote may get faulty due to various reasons:

  • Buttons are strictly
  • IR signals are not transferred to the TV due to the electric cells being expired.
  • Remote is damaged
  • Water has destroyed the electric integration of remote


  • You must first change the electric cells of your remote to check whether the voltage is delivered or not.
  • Must clean your remote with a cloth or blower or you can use a dryer to let it dry if it is water damaged.
