Roku Flashing Blue (Causes and How to Fix)

If your Roku device is blinking blue, it can be one of several possible reasons. Moving from the simplest causes to more profound ones is your most logical plan to sort out the problem.

Here are some possibilities of what can be causing a flashing blue LED.

Weak Internet Connection

Roku’s flashing blue can be an indicator of an internet issue.

Roku devices use the internet to connect to their servers and interchange data. A poor internet connection can result in a punctuated or disrupted display.

You can identify your internet strength and speed by running a connection test.

Broken Power Cord

A Roku charger won’t stay healthy forever. It’ll eventually need to get replaced with a new one. Chances are if you have an inefficient power cord, your Roku unit will flash in blue to warn you.

Poor HDMI Cables

Trying a different HDMI cord can be the ultimate solution for blue flashes. An HDMI cable is responsible for transmitting video and audio data from Roku to your TV.

Investing in a high-quality HDMI that’s durable and heat-resistant can be the best way for you to go.

Plugging RCA Cables

Unless you’re using Roku Express Plus, RCA cables will require a converter to connect to Roku. Converters add an extra layer between Roku and the TV, slowing down data transmission.

Instead, replace RCA cables with an HDMI, which offers faster signals and higher video resolution.

TV Inputs

Defective TV inputs can be the reason behind your Roku’s flashing blue.

I recommend connecting your Roku unit to a different TV set to check if the issue is from Roku or the television itself.

How to Stop Roku from Flashing Blue

If you have doubts about what’s exactly causing the blue flashing on your Roku, here are some solutions you can implement to resolve any potential causes.

Let’s check them out!

Restart Wireless Connection

Reboot your internet router or modem by unplugging it from the outlet.

Let it rest for a minute before plugging it back. You may also want to reduce the distance between your router and Roku device for a better signal. Also, make sure to remove any large obstacles standing between the two of them.

Now try again to see If the issue persists.

Replace Power Cord

Let’s walk you through the process of carefully replacing your power cord with a different one.

Unplug Roku off of electricity.
Detach the other end from the Roku device.

If the cord is connected to an adapter, take it off.
Pick the new power cable, and connect the bigger end to the charger head.
Attach the charger head to the adapter if applicable.

Insert the smaller end of the cable to the Roku unit.
Plug it into a wall socket directly.
Turn on Roku and television to see if the problem is solved.

Replace HDMI Cable

A logical next step is to replace your HDMI wire, which may be faulty and cause such a hassle.

Disconnect both TV and Roku from the power source.
Detach both ends of the HDMI cable off of the devices.

Gently connect one end of the new HDMI wire to the TV; the other end to Roku.
Reconnect both TV and Roku to the power source and turn them on.
Observe to see if the blue flashes have stopped.

Replace RCA with HDMI

If you’re using RCA cables, it’s the right time to shift to HDMI technology to avoid any glitches and bugs.

Here’s how to remove the RCA cables and connect the HDMI to one.

Unplug both TV and Roku from the power outlet.

Disconnect all ends of the RCA three cables.
Now securely connect Roku with your TV using an HDMI cord.
Plug both TV and Roku back into the power source.

Switch them on and check if the issue is resolved.

Try a Different TV

As a final resort, connecting your Roku to a different TV can bring about the desired results.

Here’s how to plug Roku into a different TV.

Separate Roku from the original television.
Plug it into the new screen and turn them all on.
Follow the guided prompts to set up Roku.

Whether the issue stops or not, re-plug Roku to the old TV to see if it works fine now.
Observe to decide if the problem is from Roku or the screen itself.
Accordingly, contact either manufacturer’s customer service.

To Conclude

If your Roku is flashing blue, the causes can vary between poor internet connection, faulty power or HDMI cable, or a defective TV.

To fix such an issue, you may want to check your internet, replace your power and HDMI cords, or use a different TV.
