Many people have experiences a flickering screen when using the Fire TV, particularly with the Fire TV 4K. There may be a few reasons for this, which I will outline below.

Incorrect Resolution and Refresh Rate

A common issue relates to the resolution or refresh rate of the display signal. First, you need to find the video resolution settings on the Fire TV. You can find these following the pathway below.

Settings > Display and Sounds > Display > Video Resolution.

First you should make due the resolution matches your TV. Some people have found changing from 1080p to 720p has solved the issue.

You can also cycle through multiple resolution options by holding down the ‘up’ and ‘rewind’ buttons at the same time. The TV will cycle through the resolution options and pause on each one, giving you time to select which one works better for you.

However, the refresh rate, or frame rate, seems to be the main issue. Try setting this to a lower value. Most people find changing the refresh rate from 60Hz to 50Hz fixes the problem.

If the refresh rate of the Fire TV is more than the refresh rate of the signal coming through the HDMI connection, or from the source, the TV will insert a blank screen in place of the missing frames to maintain that refresh frequency.

HDMI Issues

The issue may also be related to the HDMI connection. If it is not inserted correctly into the TV, the loose connection will cause your screen to flicker. Note that for the Fire TV Stick, the stick itself may not be inserted correctly into the HDMI port.

Some HDMI ports are also not compatible with certain audio-visual signals. This is mainly an issue for larger or more complex video signals, such as the 4K signal in the Fire TV Stick 4K.

For this video signal, you will need a port that supports a high-speed transfer, such as 18Gbps. It should also support 4K resolution at 60 frames per second.

As long as your HDMI port has these features, it should not have issues with the signal. If you have a HDMI port labelled ‘4K’, they generally have all of the above, but you can check your TV’s operating manual to check which HDMI port is the best.

Some people will use the HDMI extender to boost their Wi-Fi signal with their Firestick. This also keeps the bulk of the Firestick away from the other ports. However, this can degrade the video signal and cause flickering.

If you can, try plugging the Firestick directly into the TV instead. This will reduce the distance the video signal has to travel.

Fire TV Keeps Blinking

If the blinking you are referring to is the LED light on the Fire TV, it is trying to indicate that something needs your attention. If this is the case, the color of the light also makes a difference.

Blinking Amber Light

The Fire TV Stick will blink an amber color if it is trying to pair with the remote or the remote is in discovery mode. This may occur if the remote batteries are low or if you have just purchased a new remote.

To fix this, replace the batteries if necessary and re-pair the remote. You should be automatically prompted to pair the remote, in which case you just need to hold down the ‘Home’ button for 10 seconds. However, you can also manually pair it by following the steps below.

Step 1: Download the Fire TV remote app on your phone to use as a temporary remote control.

Step 2: Go to the Home screen and select ‘Settings’.

Step 3: Select Controllers > Fire TV Remotes > Add New Remote.

Step 4: Hold down the ‘Home’ button for five seconds on the remote you are trying to pair.

Step 5: Once the remote can be seen on the list, use your phone to select it, completing the pairing process.

If your remote is still working while the Fire TV is blinking a yellow light, it could also mean you have no internet connection. First, make sure you have enabled Wi-Fi connections on your Fire TV by following the pathway below.

Home > Settings > System > Wi-Fi

Your home internet connection could also be down. You will need to restart you modem/router to fix this. You also need to make sure both your modem and Fire TV are not within a cabinet. This will disrupt the Wi-Fi signal.

Pulsing White Light

If the light is a pulsing white light, it is likely that your Fire TV is in setup mode. Every time the Fire TV starts up the white light will pulse until the start-up is complete. If the start-up has failed, you might find the Fire TV is stuck on the logo screen, or functions may not work correctly.

If this is the case, you may need to do a hard restart of the Fire TV. This is done by unplugging the power for three seconds, and then plugging it back in.

Alternatively, this may occur if there are issues with the HDMI connection. First, check that the connection is secure, or you can try plugging it into a different HDMI port.

Sometimes using a HDMI extender can also affect the connection, so try plugging the Firestick directly into the TV’s HDMI port. Ensuring you are plugged into a high-speed HDMI port will also help the Fire TV start up quicker.
