When your Toshiba TV refuses to turn on, it can disrupt your entertainment plans. Fortunately, many issues can be resolved with simple troubleshooting steps. This guide covers common causes, step-by-step fixes, and advanced solutions to get your TV back in action. Written in clear, easy-to-follow language, this post aims to help you diagnose and fix the problem quickly.
Common Causes of Toshiba TV Not Turning On
Understanding why your Toshiba TV won’t turn on is the first step to fixing it. Here are the most common reasons based on user reports and expert advice:
- Power Supply Issues: Faulty power cords, outlets, or internal power boards can prevent the TV from powering on.
- Remote Control Problems: Dead batteries or a malfunctioning remote may make it seem like the TV isn’t working.
- Standby Mode Issues: The TV might be stuck in standby mode, indicated by a red light, but no response.
- Hardware Failures: Damaged internal components, like the power or main board, can cause complete power failure.
- Firmware Glitches: Outdated or corrupted software can stop the TV from functioning properly.
Step-by-Step Troubleshooting Guide
Follow these steps in order, starting with the simplest solutions. These fixes address the most common issues reported by Toshiba TV users.
1. Check the Power Supply
A faulty power connection is often the culprit. Here’s how to verify it:
- Ensure the power cord is securely plugged into both the TV and the wall outlet.
- Test the outlet by plugging in another device, like a lamp, to confirm it’s working.
- Inspect the power cord for fraying or cuts. If damaged, replace it with a compatible cord.
2. Power Cycle the TV
Power cycling resets the TV’s electronics and can fix temporary glitches. Follow these steps:
- Unplug the TV from the power outlet.
- Wait for at least 60 seconds to allow residual power to drain.
- While unplugged, press and hold the TV’s power button for 30 seconds.
- Plug the TV back in and try turning it on.
This method often resolves issues caused by software glitches or standby mode problems.
3. Check the Remote Control
If the TV doesn’t respond to the remote, the issue might be with the remote itself:
- Replace the batteries with fresh ones, ensuring correct orientation.
- Clear any obstructions between the remote and the TV’s infrared sensor.
- Try using the power button on the TV itself to rule out remote issues.

4. Inspect the Standby Light
Many Toshiba TVs have a standby light that provides clues about the issue:
- Solid Red Light: Indicates the TV is receiving power but is in standby mode. Try pressing the power button on the TV or the remote.
- Blinking Light: Suggests a hardware issue. Check your TV’s manual for specific blink codes, which can indicate problems like a faulty power board.
- No Light: Points to a power supply issue, such as a disconnected cord or failed power board.
5. Reset the TV to Factory Settings
A factory reset can fix software-related issues but will erase all custom settings. If the TV powers on but behaves erratically, try this:
- Navigate to the settings menu, usually under “System” or “Setup.”
- Select “Factory Reset” and confirm.
- If you can’t access the menu, check your TV’s manual for a reset button or combination of buttons.

6. Update the Firmware
Outdated firmware can cause power issues. To update:
- Connect the TV to the internet and check for updates in the settings menu under “Device & Software.”
- Alternatively, download the latest firmware from our Toshiba TV Firmware Downloads page and install it via USB, following the instructions provided.
7. Check for External Device Issues
Connected devices like gaming consoles or streaming sticks can interfere with the TV’s power:
- Unplug all external devices from the TV’s HDMI or other ports.
- Try turning on the TV without any devices connected.
- If it works, reconnect devices one by one to identify the faulty one.
8. Wait and Retry
In some cases, leaving the TV unplugged for a day can resolve temporary issues:
- Unplug the TV and wait for 24 hours.
- Plug it back in and try turning it on.
This can help if the TV’s internal components need time to reset.
Advanced Solutions for Technical Users
If the above steps don’t work, the issue may require technical expertise. Proceed with caution, as these steps involve risks like voiding the warranty or electrical hazards.
Replace the Power Board
A faulty power board is a common cause of power failure. Signs include a burnt smell or no standby light. To replace it:
- Order a compatible power board for your TV model from a reputable supplier, such as eBay.
- Unplug the TV and lay it face down on a soft surface.
- Remove the back panel, take photos of connections, and carefully replace the board.
- Ensure the board number matches your TV’s specifications.
Warning: Only attempt this if you’re experienced with electronics. Incorrect handling can cause injury or further damage.
Inspect Internal Components
If comfortable, open the TV to check for visible damage:
- Look for burnt or melted components, like capacitors or wires.
- Use a multimeter to test for continuity if you have the skills.
- If damage is found, consult a professional or replace the affected part.
Caution: Opening the TV may void the warranty. Check with Toshiba before proceeding.
When to Contact Toshiba Support
If none of the steps resolve the issue, it’s likely a hardware problem requiring professional repair. Contact Toshiba Support for assistance. Provide your TV’s model number and describe the issue, including any standby light behavior. If the TV is under warranty, repairs may be covered.
Preventing Future Issues
To avoid power problems in the future:
- Use a surge protector to shield the TV from power surges.
- Keep the TV’s firmware updated to prevent software glitches.
- Avoid overloading outlets with multiple devices.
