How to Fix a Roku TV Black Screen (STEPS)

Why does my Roku TV have a black screen?

The main reason why a Roku TV is showing a black screen is because a connected cables is loose, the power supply is faulty, or the TV backlight is damaged.

 

Causes

• Loosely connected cables
• Insufficient/ unstable power supply
• Damaged TV backlight

 

Loosely connected cables

Loosely connected HDMI cables send unstable and interrupted signals to your TV’s main board. This causes the screen to put up a black display since it can’t figure out what to show.

 

Insufficient/ unstable power supply

Insufficient/ unstable power supplies are usually because of loosely connected power cables. When this is the case, your TV doesn’t get enough electricity to operate normally, and so your screen doesn’t work.

 

Damaged TV backlight

Lastly, a damaged piece of internal hardware – especially the backlight – can cause your TV’s screen to appear black. When the backlight is damaged, your TV can’t display its images normally.

 

How do I fix my Roku TV’s black screen problem?

You can fix a Roku TV black screen problem by conducting a soft reset, a factory reset, ensuring your TV has the correct input source, checking your cables, or calling customer support for a replacement/ repair.

 

Soft Reset

Here are the steps:

1. Turn off your TV using the remote.
2. Now, remove the power cable from the socket.
3. Now, press down on the power button of your TV (not on the remote; on the device itself) and hold it down for at least 30 seconds.
4. This step ensures that all residual power from within your device gets drained out.
5. Now, release the power button and let your TV rest for at least 10 minutes.
6. After this, plug your TV back into the socket and use the remote to turn it on.

 

Ensure that your TV has the correct input source

Roku devices attach to one of the video ports on your TV. When you face a black screen issue, immediately check whether you’re using the correct input source. You can check this by clicking on the “input/ source” button on your TV’s remote.

 

Check all connected cables.

Sometimes, loosely connected data cables, i.e., HDMI cables, can cause your TV to blink a black screen. This issue can be resolved by disconnecting all connected wires from your device and then reconnecting them securely back into your TV.

 

Factory Reset

Factory resets wipe out any saved apps/ personal data from your TV, so only do it if you’ve exhausted all other options.

 

Here are the steps:

1. Use the remote and navigate to settings.
2. Then, find system settings.
3. Click on Advanced system settings.
4. Now, find the factory reset option.
5. Press “ok” on the confirmation prompt.
6. Your TV will reset to factory default.

 

Call customer support

If none of these methods work, the issue is probably a hardware issue. In such cases, you can’t fix your TV on your own. Call an expert technician to take a look at your TV. See whether your TV needs to be repaired or replaced.

 

 

How do I reset a Roku TV with a black screen?

There are 5 different ways you can reset your Roku TV to fix your black screen issue. They are, namely, simple restart, power cycle (soft reset), connection reset, remote reset, and factory reset.

 

If none of these solutions work, your TV has a hardware issue.

 

Here is how you can conduct each of these resets to fix your TV’s black screen issue:

7. Turn off your TV using the remote.
8. Now, remove the power cable from the socket.
9. Now, press down on the power button of your TV (not on the remote; on the device itself) and hold it down for at least 30 seconds.

12. After this, plug your TV back into the socket and use the remote to turn it on.

 

Connection reset

If neither of the two methods above does the trick, you should consider a connection reset. This method essentially involves removing all cables connected to your TV, cleaning their ports, and then firmly plugging them back in.

8. Then, find system settings.
9. Click on Advanced system settings.
10. Now, find the factory reset option.

Why does my Roku TV’s screen go black, but the sound still works?

The reason why a Roku TV screen has gone black (but the sound still works) could be because the TV’s internal display backlighting has failed, the TV software is not up to date,  or because of a corrupted motherboard.

 

Causes

• Internal hardware issue, i.e. the display backlighting has failed
• Software not up to date.
• A glitch.
• A corrupted motherboard.
• A damaged screen

 

Internal hardware issue

If your screen’s backlight panel is damaged, your screen will not display anything, but the audio system will still work. This could be the reason behind your TV acting up this way.

 

Software problem

Bugs can sometimes cause your screen to stay blank while the audio plays in the background. Software updates come to fix bugs, so if you haven’t updated your device to the latest version, your issue may be due to bugs.

 

Glitch

Sometimes, these problems are caused by random glitches that temporarily leave your screen blank while your audio still works.

 

Corrupted motherboard

If your TV’s motherboard is corrupted, it can’t send signals to your display panel and tell it what to show on the screen. The result is a black light constantly blinking on the screen.

Sometimes, the motherboard is still able to send signals to your TV’s speakers telling them what audio to produce. This way, your TV’s display remains black while the audio plays just fine.

 

Damaged Screen

A damaged screen could be another reason why you’re seeing a black display but hearing the audio correctly. TVs are fragile devices.

You can easily damage their screens by dropping them or applying force to the screen. This way, even though the motherboard sends the correct signals to the display. The screen shows nothing.
