Check the Power Cords

If your Xfinity Flex is displaying a black screen, then there’s some possibility that your Xfinity Flex or TV is having some fault in cable connections. Earlier, there were cases where users encountered black screen issues due to the frayed, damaged or torn wire. So, try to check all your cables that are connected to your Xfinity Flex and TV. 

If you’ve found any torn, damaged or frayed cable, we suggest you replace that cable with the new one and connect it securely to your devices. After this, turn on your devices and check if this resolves the black screen issue. 

Also, ensure that all the cable connections are tightly connected to your devices. Check all the cables separately.

Try Changing the HDMI Cable

If you’ve found that your HDMI cable is broken or frayed, then try to replace it with another one. Connect your new HDMI to both your devices and check if this works for you.

Try Changing the HDMI port and setting the correct input.

If changing the HDMI cables doesn’t work, try connecting your HDMI cable to another port. There are 2-3 HDMI ports at the back panel of the TV, so try connecting your HDMI cable to a number 2 or 3 port. 

After changing the HDMI port, press the Input button on your TV remote and set it to the right HDMI input. 

Check your Power Outlet

If you’re still experiencing the black screen, then there might be some issue with the power outlet to which your devices are connected. Your devices might not be receiving adequate power to run.

In this case, you need to ensure that the power cables of your TV and Xfinity Flex are plugged into the working power source or outlet. There were some cases where faulty power outlets stopped devices from working properly.

To check this, you can try to connect your other devices to the same power outlet or try connecting your TV and Xfinity Flex to a nearby wall outlet. 

Also, ensure that you aren’t using any power strip or extension board to connect your devices. If you’re using any, then unplug your devices and connect them to the wall outlet.
