How to update the firmware on a Toshiba TV

When using Toshiba TVs, the message “Do not power off” may appear. The phrase indicates the need to update the firmware. The procedure is simple, so even an inexperienced user can handle it. In rare cases, you can fix the error by checking the “Input Labels” (EXIT or HDMI), but in most situations only updating will save you. The TV should be flashed according to a certain algorithm, and the instructions for different models are similar, both for Toshiba 23EL933RK and for Toshiba 42HL833R.

What is firmware

When using Toshiba TVs, the message “Do not power off” may appear.
Firmware is the software responsible for the normal operation of the TV. If there is no new firmware, the TV will not turn on.

Why do we need updates?

During operation of the device, software glitches and errors in the operation of memory chips occur. Toshiba TV firmware will allow you to update the software and replace the contents of the memory.

Important! Before starting the update, you should save the existing data to removable media. This will allow you to return the old firmware version if the installation of the new one is unsuccessful.

Factory settings

If the problem persists after rebooting, perform a factory reset.

Note.

Performing a factory reset will erase all data and settings on the TV (for example: Wi-Fi and wired network settings information, Google account and other login information, Google Play and other installed applications).

1. Press the HOME button, then select [Settings] - [Storage & reset] - [Factory settings].
2. Select [Delete All]. If the TV has a PIN code set, you will need to enter it after selecting [Delete All]. If the factory reset is successful, the TV will continue with the initial setup wizard. You must agree to Google's terms of service and Google's privacy policy.

Hello friends, in this article we decided to tell you how to restore your laptop to factory settings. Let's start with the manufacturer Toshiba (if you are interested, you can read a separate article - How to create recovery disks for a Toshiba laptop and recover using them), the second we will consider a Sony laptop, the third HP pavilion. Separate articles were written for Acer, ASUS and Samsung, HP, Lenovo laptops. Well, then we will try to supplement the article with information on products from other manufacturers; judging by your letters, this topic is of interest to many of our readers.

1. Good day, I wanted to ask you how to restore a laptop to its original factory settings? I know that these settings are located in a hidden partition of the hard drive, but I carelessly deleted this partition and now when I try to roll back to factory settings I get an error. I have not created recovery DVDs and in general, I have never had the opportunity to restore a laptop to factory settings. What is the way out of my situation?
2. Hello admin, please explain what I should do. A Toshiba laptop, it has a hidden partition, also a C: drive and a D: drive. I didn’t touch the hidden partition, but on drive D: I deleted everything, and now I can’t roll back to factory settings, they say Toshiba laptops use a hidden partition and some other folder HDD RECOVERY, which is located on the disk, to restore factory settings D:. What should I do now?
3. I bought a Toshiba laptop, the instructions for the laptop say, if you want to roll back to factory settings, press the F8 key, the recovery program will start. I pressed it, but Additional download options are launched and that’s it... And then what to do? And another question, when you first started it, a message appeared - We recommend that you create a resuscitator media on a USB flash drive or DVDs, using the Recovery program, it will help you restore the contents of the computer to the original factory state, even in the event of serious damage to the computer.

5. Admin, answer this question. All laptop manufacturers equip them with a special RECOVERY program, located in a hidden section. Using this program, you can roll back the laptop to factory settings in case of serious problems with the operating system. Question – Is there any alternative to this program?

Step-by-step firmware installation plan

In some cases, updates are installed automatically. You can also reflash the TV manually. To do this you will need to download the software. This can be done on the official website. There are problems finding firmware for Toshiba 32L2353RB or Toshiba 39L2353RB. Files for downloading are presented on thematic forums. But it’s better to contact the official source to get a version without any glitches.

TV firmware from flash drive

Before starting the firmware, you should prepare the flash drive for use. To do this you will need:

1. Download a program for formatting removable media.
2. Choose a flash drive with a capacity of at least 500 MG.
3. Format the media, check for compliance with the parameters of the FAT 32 file system.

Important! You do not need to format the flash drive using Quick Format. You will need to completely delete all files, otherwise the software will not be written to the media.

After cleaning the flash drive, we download the new firmware version onto it. Next, perform the following steps:

1. The TV turns off.
2. The media is connected.
3. Turn on the device.
4. Confirm update.
5. Wait for the installation of the new software to complete.

At the end of the procedure, Toshiba will reboot. During installation, it is prohibited to touch the media, since if you disconnect the flash drive from the TV during the update, the startup will be interrupted and recovery will be difficult.

Through the Internet

Flashing a TV via the Internet is easy, but you need stable access to the network. Automatic updates can cause problems, so this method should only be used as a last resort. To do this, you will need to confirm the launch of the update. The TV will automatically find the new version and download it. This option can only be tried for the Toshiba 4LV933RB and Toshiba 26EL933RB models. But you can also find software online for installation from a flash drive.

Software update via menu

If automatic updating is disabled, you can start it manually from the TV. To do this, you need to go to the menu and perform several actions:

1. On the remote control, click SMART TV and find the installation shortcut.
2. Select "Software Update".
3. Click “Search for available updates.”
4. Determine the download method – “via the Internet”.
5. Confirm your acceptance of the user agreement.

The advantage of this method is that while downloading the software, you can fully use the functions of the TV. After updating, Toshiba will need to restart.

Where is the model number?

It is necessary to flash the device if there is a new version of the software. To find out if there are updates for the model, you need to check the TV number on the official website. The data is indicated in the Toshiba data sheet, as well as on the back panel of the TV.

TV repair TOSHIBA 23EL934RK

General recommendations for repairing TV LCD LED

It is advisable to start repairing the TOSHIBA 23EL934RK TV with a careful external inspection of both internal and external elements.
Sometimes, based on visible changes in device components, it is possible to draw some conclusions and decide on the direction of further troubleshooting even before starting the necessary measurements. Experienced repairmen often guess the causes of a defect and possible consequences, for example, by ring cracks in the soldering of element leads, as well as by swollen capacitors or resistors burned to coal dust and other external indirect signs. If the UE-3470-1SUN-LF power module malfunctions, the external manifestations may be different, for example, the TOSHIBA 23EL934RK does not turn on at all and there is no indication of control lights on the front panel. With the same symptoms, the power stabilizer (converter) of the control processor may be faulty. When diagnosing and repairing a power supply, first of all you should replace the swollen filter capacitors of the secondary rectifiers and check the fuse and, if it is broken, you need to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module - rectifier diodes and transistors TF7N70, P1504EDG, AO D482 in the primary circuit. If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (SMPS) it does not fail on its own without reasons, which should be looked for by checking other elements of the primary circuit - electrolytic capacitors, PWM controller 6754MR (8), M101 1147 (6), which can only be checked by replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).

If, when you turn on the TV, the image appears and immediately disappears, or is absent initially when you turn it on, but there is sound and other functions work, there is a high probability of a malfunction of the LED driver (power converter for the panel backlight LEDs). In such cases, the general power module must also be checked, in which the electrolytic capacitors of the rectifier filter feeding the LED driver should be checked. To check the serviceability of the LEDs, as well as the contact connections in the ruler circuit, it is necessary to disassemble the panel. It is impossible to check the LED strings for breaks without disassembling the panel with a multimeter or tester. For these purposes, it is necessary to open all series-connected PN junctions and a voltage of the order of tens of volts will be required, and ideally, a current source.

Attention! Users and owners of 23EL934RK TVs who do not have the appropriate qualifications, knowledge and experience are strongly discouraged from attempting self-repair in order to avoid negative consequences that could lead to complete irreparability of the device.

How to return the old firmware version

If the software is installed incorrectly and the device does not work, you should try restoring the previous firmware version. To do this you will need:

1. Connect a flash drive with old data.
2. In the technical power-on mode, go to settings.
3. Click on “Restore previous version”.

The TV will restore the data automatically. But performance will not return for long, since you will need to flash the TV and update the software.

Regardless of the model and diagonal of the TV, it is important to have high-quality firmware and strictly follow the instructions. On the official website, the developers, along with the software, offer update rules along with the firmware file. By following the recommendations, you will be able to independently restore the functionality of any model, including the Toshiba 19EL933RB.

Why do we need updates?

There are several main reasons why users decide to flash the system:

1. Increasing the stability of the new TV device. Some TVs have so-called raw firmware, if the sample is completely new and was turned on for the first time. LG and WebOS users face this problem. All errors can be corrected using the downloaded program for the system. Having done the firmware correctly, a person will get rid of many problems.
2. Increased work speed. System firmware is often used to increase the speed of the TV. Sometimes the device responds slowly to the remote control. This applies to Smart applications, changing channels, and simply turning the device on and off.
3. TV firmware is an ideal way to expand functionality. Manufacturers release updates that increase the capabilities of an existing device. This is how additional programs and useful applications appear in the menu.
4. Solving problems with Smart TV. If you have any problems with the Smart TV function, then perhaps the preferred solution to the problem is a full software firmware. If you study user reviews on the Internet, you can understand that the firmware helped solve many problems on the TV.

To understand the purposes for which a specific update is intended, you can go to the official website of the TV manufacturer and in the appropriate section find a full description of the new firmware version. There it will be written in detail about the advantages of the program, new functions, as well as problems that can be solved.
