How to Fix When Xfinity Flex Setup Not Working?
Tip: Follow the steps in chronological order, thus by priority!
1. Soft-Reset Xfinity Flex Equipment
The very first step is to inspect the power supply of the Xfinity Flex cable box and ensure that the device is working.
This is the fastest and most straightforward way to deal with temporal issues related to the Xfinity Flex bugs and glitches!
- To soft-reset the Xfinity Flex, unplug the box from the power for 60 seconds!
In the meantime, test whether the power outlet is functional by plugging in a phone charger or a lamp only to verify the workability.
In addition, we recommend plugging the Xfinity Flex directly into the power outlet without any power splitters involved in the setup.
2. Select the Correct TV Source!
The next step by priority is to check and verify whether the correct TV source is selected, where the Xfinity Flex cable box is connected to.
For instance, if the Flex TV box is connected to HDMI 1 on your TV, in the TV sources menu you should select the 1st HDMI input for broadcasting.
- On most TVs there is a “Source” or “Inputs” button on the remote control.
In case the remote doesn’t have such a button, press the “Home” button and go to Settings > Inputs or Sources, and cycle through.
In case you’re finding it hard to check or recall where the TV box is connected, simply test all available sources until the image appears on the TV.
3. Reconnect & Test the Video Cable
In case the setup won’t begin and you’re seeing “no signal” on the screen of the TV, it’s due to a fault with the video signal.
The inspection requires a thorough examination of the cable’s ports, the connectors, and the general cable condition.
Follow the steps below to inspect and examine the HDMI cable:
- Turn off your TV and Xfinity Flex cable box.
- Disconnect the power adapter on both units.
- Unplug the HDMI cable on both devices’ ends.
- Inspect the input ports for dust accumulation.
- Remove any obstructions inside the ports.
- Thoroughly check the HDMI cable connectors.
- Plug the HDMI cable tightly on both sides.
Reminder: In case you’re wondering how to set up Xfinity Flex, use the steps provided earlier in the guide for the correct approach.
4. Inspect the Xfinity Flex Internet
If you’re encountering issues completing the Xfinity Flex cable box setup, it’s important to check whether your home internet and WiFi are intact.
During the setup process, you need to connect the Xfinity Flex to the WiFi, which wouldn’t be possible without a reliable internet connection.
Xfinity Flex Connected via WiFi:
If you’re attempting to connect the Xfinity Flex to the WiFi during the setup but the process keeps failing, pull out your smartphone and connect to the same WiFi.
Then open the web browser and test whether the WiFi is stable and you’re able to surf the web.
Xfinity Flex Connected via Ethernet:
If you’re using a wired connection, ensure to specify this during the setup and reboot the network router to ensure that all services are refreshed.
In addition, you can use any computer connected to the router via an Ethernet cable to check whether the internet connection is intact.
Tip: Feel free to test connecting your Xfinity Flex to a shared (mobile hotspot) from your phone!
5. Factory Reset Xfinity Flex Box!
In case the Xfinity Flex box setup not working, don’t worry since performing a reset is always one of the best-working approaches.
In case you didn’t know you are able to perform a reset before setting up the cable box, which is one of the best ways to do so (manually).
- Locate the reset pinhole on the back of the Xfinity Flex!
Inside the pinhole, there is a reset button that will factory reset the Xfinity Flex when held for about 10 seconds.
In case your Xfinity Flex does not have a reset, button try the steps below:
How to Factory Reset Xfinity Flex via Remote?
- First, reset the remote by holding the A and D buttons.
- Wait until the remote light flashes green and releases.
- Then press 9 – 8 – 1 on the remote and the light will flash.
- Next, press the power button for 3 seconds on the remote.
- Next, tap OK, then the Right Arrow, Down Arrow, and Power.
If done correctly, the Xfinity Flex will restart and revert to factory default settings after which you’ll be ready to re-attempt the setup.
Don’t forget to use the steps at the beginning of the guide as a reference to set up the Xfinity Flex 4K box correctly.
6. Test with a Different Monitor!
In case you’re unable to see anything on the TV screen even when the Xfinity Flex is connected and working, perhaps the fault is with the TV.
This is why the best next step before we can draw a conclusion should be to connect the Xfinity Flex via HDMI cable to another TV or a monitor.
In case the visuals now appear, when the TV box is connected to another destination, then perform a factory reset on the TV or check the sources.
However, in case your Xfinity Flex does not appear even when connected to a secondary monitor, replace the video (HDMI) cable.
Tip: You can use any computer monitor that supports HDMI input as well as old (non-smart) TVs, as long as there is HDMI input on the back or on the side.
Xfinity Flex Step Still Not Working…
In case nothing from the guide helped and you’re suspecting the Xfinity Flex cable box might be faulty, it’s best to consult with a qualified professional.
The best way is to contact Xfinity Customer Service to reach out to the local supplier in an attempt to claim your warranty!
Quick Recap:
Here we’ve learned that when the Xfinity Flex setup not working we should soft-reset the entire equipment first and then check the video cable.
