Won't Turn On: How To Fix Comcast Box After Power Outage?

Comcast is one of the most well-known companies that offers a variety of networking and entertainment options for your home. Since it is a well-known brand in North America, its services are mainly used in the United States.

If you're dealing with a similar issue, this article will be extremely beneficial to you. We will provide you with a range of troubleshooting measures in this post. These steps should assist you in resolving the issue.

The following is a list of all of them:


Switch it off for a few minutes and see what happens.

If the box suddenly stops working after a recent power failure, you can try to turn it off in the hopes of solving the problem. We suggest that you switch the box off fully and remove the batteries (if it has any).

Make sure the box is turned off for at least 30 minutes before turning it back on. Try reconnecting it once it's turned back on, and it should start working again.


It's possible that the power supply has been affected.

The power supply of the box could have taken some damage as a result of the power outage, which may be the cause of your problem. While it is extremely unlikely, a sudden voltage spike may be the cause of the power supply's failure.

It's also possible that a fuse blew or that the circuit breaker tripped. We recommend double-checking them just to be sure.

Contact Comcast Cable

If none of the procedures seem to work for you, you can try contacting the cable company for additional assistance. If the equipment is truly defective, they should be able to assist you in getting it replaced.

They should also be able to figure out why you're having problems with your Comcast box.


How do I check if there is an Xfinity outage in my area?

Here are a few steps you can take:


  1. Check the Xfinity Status Page: Visit the Xfinity status page or their official social media accounts to see if they have posted any updates about outages in your area.

  2. Contact Customer Support: You can call Xfinity's customer support to report the outage and get an estimated time for when the service will be restored. They might also be able to provide more information about the cause of the outage.

  3. Reset Equipment: Sometimes, resetting your modem and router can help resolve connectivity issues. Unplug both devices, wait for a minute, and then plug them back in.

  4. Check Nearby Devices: If your neighbors are experiencing the same issue, it's likely a widespread outage. If it's only you, the problem might be with your individual connection or equipment.

  5. Use the Xfinity App: You can also use the Xfinity app on your smartphone to troubleshoot and check for outage information specific to your location.

  6. Wait for Updates: If the outage is due to a network issue, the best thing you can do is wait for Xfinity to fix it. They are usually quite responsive to restoring service.
