Toshiba 43U6763DB user manual

There are a few possible reasons why your Toshiba TV won't turn on even though the red light is on:
1. Power supply: Make sure the TV is properly connected to a power source and that the power outlet is functioning. Try plugging the TV into a different outlet or using a different power cable.
2. Remote control: Ensure that the batteries in the remote control are not dead. Try manually turning on the TV by pressing the power button on the TV itself instead of using the remote.
3. Sleep timer: Check if the TV's sleep timer is activated. The sleep timer might have been set to turn off the TV after a specific period of inactivity.
4. Power surge: If there was a power surge or outage, it could have caused the TV to enter a protective mode. Unplug the TV from the power source for a few minutes, then plug it back in and try turning it on.
5. Software/firmware issue: Sometimes, software or firmware glitches can occur, preventing the TV from turning on. Try performing a hard reset on your TV. This typically involves pressing and holding the power button for 10-15 seconds or unplugging the TV and holding the power button for the same duration. Consult your TV's user manual for specific instructions.
If none of these solutions work, it may indicate a hardware-related issue, and it would be best to contact Toshiba customer support or a professional technician for further assistance.

1. Control Buttons: Most Toshiba TV models come with control buttons on the side or bottom panel. These buttons allow you to turn the TV on, change the volume, switch the input source, and navigate the menu options.
2. Smartphone Apps: Several universal remote apps are available for smartphones that will allow you to control your Toshiba TV. Make sure that your TV is smart and can connect to Wi-Fi, then download and install a compatible app on your smartphone. Apps like Sure Universal, Peel Universal and AnyMote are popular choices.
3. TV Controller Box: These are devices like Roku, Apple TV, or Android TV boxes that come with their own remote control. These can often be used to control other functions of your TV like changing the volume and turning the unit on/off.
4. Voice-Controlled Assistants: If your Toshiba TV is compatible with voice control technologies like Google Assistant or Alexa, you can use these to control your TV. For this, ensure your TV is properly set up to be controlled by these devices.
5. HDMI-CEC: This feature allows you to use the remote of a connected device to control multiple devices. For instance, if your TV and your DVD player are connected via HDMI and both are HDMI-CEC compatible, you could control both devices with just one of the remotes.
Before using these alternative methods, you should consult your TV's manual or the official Toshiba website to find a solution specific to your TV model.

There could be several reasons why your Toshiba TV screen is black. Here are a few possible causes:
1. Power issue: Make sure the TV is receiving power by checking if the power indicator light is on. If not, try plugging it into a different power outlet or using a different power cord.
2. Input issue: Ensure that the input source is correctly selected. Press the "Input" or "Source" button on your TV remote and cycle through the available input options until you find the correct one.
3. HDMI or other cable problem: Check the cables connecting your TV to any external devices. Make sure they are properly plugged in and not damaged. Try using a different HDMI or AV cable to rule out cable faults.
4. Display settings: Check the brightness and contrast settings on your TV. They might be set too low, making the screen appear black. Try adjusting these settings using the TV remote.
5. Software or firmware issue: It's possible that the TV's firmware needs to be updated or it might be experiencing software-related glitches. Visit the Toshiba support website and look for any available firmware updates for your specific TV model.
If none of these solutions work, it might be best to contact Toshiba customer support or consult a professional technician to diagnose and fix the issue.
