Roku TV Black Screen

You turn on your Roku TV, and you’re greeted with a black screen. You try to power it on and off and mash different buttons on your remote, hoping to bring it back to life. Is it time to send your Roku TV to the nearest e-waste collection center, or is there a way to resolve this problem?

Roku TV Black Screen

Roku TVs can show black screens due to backlight damage, faulty or loose power cable, or operating software (OS) bugs. Power cycling the device, checking the cables for connectivity and damage, and performing a factory reset may help fix this issue. 

Understanding why your Roku TV is facing this problem is a great place to start. This article will explain why your Roku TV has a black screen and methods you can use to correct it. 

What’s Causing the Black Screen on My Roku TV?

As alarming as looking at a black screen on your Roku TV may be, the first step is to identify the issue. Read on to understand the different reasons for your Roku TV’s black screen.  

Damaged or Loose Power Cable

Check the power cable attached to your Roku TV. Sometimes, when you were moving your device around, it became loose. Or, if you have a pet (especially a cat), its shenanigans might have dislodged the cable or damaged it. 

You can try fixing it if the cable is simply loose. However, if the power cable is damaged, you might have to replace it entirely. 

Unexpected Errors in Operating Software (OS)

Sometimes, errors in the OS can go unnoticed, and they may get pushed to your Roku TV, causing your screen to go black. 

Issues with the OS leading to black screen are common across smart TVs and their accessories like the Fire TV stick. If you want to learn more about that, you can read our article about fixing Fire TV Stick Black Screen

As you can’t see anything on the screen, it’s impossible to check whether an update can address this issue. Check your power cables to eliminate any issues from that end before you consider any potential software issues. 

Backlight Failure

Liquid Crystal Displays (LCDs) don’t produce light on their own, unlike Organic Light-Emitting Diodes (OLED) and Active-Matrix Organic Light-Emitting Diodes (AMOLED) screens. This is why LCD TVs require a backlight, which helps illuminate the image on the screen.

Backlights fail because the diode (light emitting device) burns up, the internal wiring gets damaged, or because of defective parts. 

Here’s how you can check if the backlight on your TV is no longer working.

  1. Turn on your Roku TV using a remote. 
  2. Turn the flashlight on any device, such as a smartphone, tablet, or torch.
  3. Place the flashlight as close as possible to the TV.
  4. Get close to the TV screen and see whether you can see a faint image. It will look as though the brightness of the TV is extremely low.

If you can see an image, your Roku TV’s backlight is no longer working. In the case of backlight failure, the best option is to reach out to your TV manufacturer. If your device is under warranty and meets the requirements for free repair, they will replace it. You may have to pay for out-of-warranty repairs.
