If you’re facing the Toshiba Fire TV sound but no picture problem, there’s an easy solution!
The presence of an audio output often indicates that the TV hasn’t sustained lethal damage to the hardware or the OS.
However, anything running from a power supply fault, improper input selection, TV brightness problems, and a handful of causes could all lead to a black screen.
Hence, we recommend the following solutions:
For a thorough rundown of the solutions, proceed with the comprehensive guide!
How to Fix the Toshiba Fire TV Sound But No Picture Issue?
Note: Does pressing the “Settings” button on the remote bring up the system menu?
1. Reconnect the TV From the Power
The first proven resolution to issues with the Toshiba Fire TV’s video reception is to perform a power cycle.
The procedure involves temporarily suspending the power supply of the TV until all of the residue electricity has drained completely from both the TV and the power equipment.
Follow these instructions to power cycle the Toshiba Fire TV easily:
- Press the “Power” button on the TV’s remote control.
- Next, disconnect the TV’s power cable from both ends.
- Wait 60 seconds while the Toshiba Fire TV is draining.
- Reconnect the power cable to the power port of the TV.
- Connect the other end of the cable to the power outlet.
- Use the remote control to turn on and test the Toshiba TV.
If the black screen is still there, check if the TV responds to the remote control in any way.
If the device is stuck on the video you were watching and the sound isn’t going out, there’s a consistent chance that the remote control will still be functional.
2. Switch the Toshiba Fire TV Inputs
So, a defect with the input selection may initially lead to the Toshiba Fire TV sound but no picture issue.
This is why the next step is to use the remote control to cycle through all available inputs on the TV and determine if the black screen persists.
- To change the inputs on the Toshiba Fire TV, press the “INPUT/ZOOM” remote button!
If the menu does appear, try switching through multiple sources, whether or not there’s a device connected to the physical input.
Important: Disconnect External Devices!
External wired or wireless devices can potentially contribute to the condition of your Toshiba Fire TV, so now is the time to disconnect them.
Note: Ensure the only cable plugged into the TV during the time of testing is the power adapter!
3. Adjust the Toshiba Fire TV’s Brightness
If you’re uncertain whether or not the TV’s brightness has been set to a minimum, there’s a quick way to adjust the feature’s value in the picture settings.
If the brightness is set to low, you will be able to navigate through the TV menu by eliminating all light sources near the TV.
Consequently, here’s how to adjust the Toshiba Fire TV’s brightness:
- Hold the “Home” or “Settings” button on the TV’s remote.
- Once the menu appears, select “Picture” and scroll down.
- Search for the “Brightness” field within the options menu.
- Highlight the bar using the remote and increase the value.
- Exit the TV’s picture menu and check if the issue is there.
Tip: If able to navigate through the menu clearly, set the brightness to 70%-80%.
4. Test the Backlight of the Toshiba TV
Before proceeding further with any of the solutions, it’s recommended to check if the backlights of your Toshiba TV have defected by chance.
A hardware malfunction with the lightning found behind the display may make it look like a TV input problem, while the screen is very, very dim.
4.1 How Does the TV Backlight Work?
The backlight LED is installed on par with the LCD panel, designed to emit a light beam through the panel in order to create an image.
Using the TV’s picture settings, you’re indirectly operating the lightning effects to create different shades and colors of the LCD panel.
4.2 How to Test Toshiba Fire TV Backlight?
The easiest and proven method for testing the backlights of your TV is to use a flashlight to shine very close to the screen’s surface.
Ensure the flashlight is set to maximum strength and try to check the TV’s broadcast by looking directly through the beam.
If you can see the TV’s menu only through the flashlight’s beam, it means that the backlight is defective.
4.3 How to Inspect or Replace TV Backlights?
Unfortunately, inspecting or replacing the TV’s backlight requires a disassembly of the internal parts.
If you’re inexperienced or prefer not to void your warranty, it’s recommended to deliver the TV for a warranty inspection or have a specialized technician do it for you.
5. Execute the Factory Reset Shortcut
An extremely effective way to address the Toshiba Fire TV sound but no picture issue is to execute the factory reset shortcut.
Pressing and holding a combination of buttons on the remote allows for a full OS cleanup which should almost certainly resolve the black screen.
- Press the “Back” and “Right” direction buttons on the Toshiba Fire TV remote.
Release the buttons after approximately 10–12 seconds and wait for the factory reset to take effect.
Verify the TV is on, and that you can still hear the sound before inserting the combination.
6. Inspect the TV’s Internal Components (Advanced)
There’s a high possibility that the TV could have sustained minor damage to the hardware.
If the TV’s warranty has already expired, or you’re willing to pay for the repairs afterward, it is preferable to conduct the inspection yourself.
The Toshiba Fire TV’s hardware is relatively easy to navigate and does not require much technical knowledge, but follow our instructions closely.
Here’s how to inspect the TV’s internal components in easy steps:
- Unplug all of the TV’s cables and lay the TV flat on the ground.
- Locate the screws that are holding the LCD housing attached.
- Use a Phillips screwdriver to uninstall the screws on the TV.
- Carefully lift the LCD housing to expose the TV motherboard.
- Remove the connector plugging with the main board of the TV.
- Important: Check if there’s any damage to the TV motherboard.
- Proceed with removing the screws holding the LCD assembly.
- Important: Conduct a thorough examination of the TV backlight.
Search for the following types of damage:
- Burnt spots
- Capacitor damage
- Burnt connectors
- Broken segments
- Weird odor
If you notice any of the following, it’s perhaps time to seek professional help with your black Fire TV screen defect.
If you’re confident you can replace the part itself, all segments in your Toshiba Fire TV have their serial number imprinted, so you can find the replacement parts more easily.
