How to Fix Xfinity HD Channels Not Working?

In this comprehensive step-by-step tutorial, we’ll be sweeping every possible cause.

We’ll try to solve it from each of their strands, so you’re not left with any problem.

Step #1: Ensure That You’re Subscription Includes the Channel/s You’re Accessing

The first thing you want to check is your subscription. It’s possible that the reason you can’t access HD channels is because you’re not subscribed to it properly in the first place.

So, what you want to do is to ensure that your subscription includes the channels you’re trying to access.

You can do this by checking your online billing statement or by accessing manage my subscription.

Checking the Bill

Whether you have physical or online billing, you’ll be able to see the level of subscription you have with Xfinity. You simply have to get your latest bill and go to the Services part.

Check what subscription you’re under and cross-reference it with what’s included in the package via the Xfinity website.

Selecting “Manage My Subscription”

You can also check if by checking your subscription.

1. On your TV, go to Your Network > On Demand.
2. From there, select Networks > Subscription Add-Ons.
3. Then, select Manage My Subscription.
4. Search for the channel in question and check if it’s part of the package.

Step #2: Check If You’re on the Correct TV Input

When you’re certain that the problem isn’t with your subscription or how it’s set up, the next thing to check is the input of your TV.

Sometimes, we often forget that our televisions have many different inputs, causing confusion.

Here’s how you can check if you’re on the correct Input/Source of your TV.

1. Grab your TV’s original remote.
2. Then, select Input or Source.
3. Check if you’re on the correct HDMI port where the box is connected to.

QUICK TIP: If you’re seeing the Xfinity user interface (UI) on your TV screen, then you’re most likely on the correct input.

Step #3: Check If There’s An Xfinity Outage or Maintenance Issue

Before we go on any further, check if there’s maintenance or an outage going on with Xfinity’s servers.

You can do this in a few different ways, but the fastest and most reliable method would be to check Comcast’s Status Center.

Follow these steps to do this properly:

1. Log into your Xfinity account.
2. Scroll down to Services > Overview > Status Center.
3. Then, select the Devices tab.
4. From there, the system will tell you if there’s an outage or maintenance going on.
5. The service will be in the red color if there’s a problem; otherwise, it wouldn’t have any color.

Checking the Comcast Outage Map

Alternatively, you can also use Comcast’s Outage Map to track and trace an outage.

In the Status Center, tap on View Outage Map and wait for the map to appear.

Type your address and wait for the system to load the information up to know if your area is currently under a service outage or a system update. 

Step #4: Power Cycle the Box

What you want to do next is power cycle your Xfinity box.

Some of you may argue that power cycling is as simple as restarting it via the remote or the panel, but that does not drain all the power inside the box.

To perform a more thorough and comprehensive power cycling, power the Xfinity box off completely. Then, unplug it from power.

Wait for up to three (3) minutes, and plug it back in again, and turn its power back on.

Detach and Reattach All Wires and Cables

Before turning it on again, though, you want to ensure that all wires and cables are inserted and connected properly.

Improperly connected and plugged-in cables can cause problems like distortion, blurred picture quality, inability to access, etc.

So, while turned off, detach or disconnect all cables and connect them back into their respective ports securely and properly.

Connect to a Different HDMI Port

It can also help to reroute the HDMI port to another port on the back of your TV. This is to test out the HDMI port where it’s currently connected to.

QUICK NOTE: When you do this, just make sure that you’ll switch the input to the correct HDMI port. 

Step #5: Update Your Xfinity Box’s Firmware

Last, but most definitely not least is to force an update of your Xfinity box’s firmware.

Although these boxes update automatically, mishaps could happen; they might not push through with the update on their own.

To do the update manually, here’s what you need to do:

1. Ensure that the remote has batteries.
2. While pointing at the box, press [UP], [UP], 2, 3, 4, 7, 6.
3. Then, wait for the system to recognize this action.
4. Go through the guided setup or the on-screen commands.

That’s it! That’s the comprehensive take of how you can troubleshoot the problem if your Xfinity HD channels aren’t working.
