In a nutshell, if your Xfinity Box says PST, it could be as a result of a signal outage issue or physical damage on your device. We will explain these in detail in the latter part of this post.

Why Is My Xfinity Box Showing PST Error?

There are several reasons why you are seeing the PST error message on your TV when you try to access your cable box. Below are some of the possible reasons:

a. General Signal Outage

One common reason why you may be seeing the PST on your Xfinity could be that there is a signal outage. The signal outage can be a general one affecting your area, or just a signal outage of your device. For instance, if the weather is bad, stormy, or very windy, these could affect the signal.

b. Damaged Cables

Another reason could be damage to the cables connected to your Xfinity box. It could be that the cables are loose, worn out, or outrightly damaged.

c. Using Splitter

A splitter is used to split the signal between more than one device. The thing about using a splitter is that it tends to weaken network signals. It can also cause an outright network failure in rare instances.

5 Ways To Fix My Xfinity Box Showing PST Error?

These are some ways to fix the PST error in your Xfinity box and get it working in no time.

a. Reboot Xfinity Box

It may be tempting to start checking for a technical solution when you experience an issue with your cable box. But a basic step like resetting your Xfinity box can fix the issue.

To reboot your XFINITY cable box, simply remove the power cord from the power source. Wait for at least 30 seconds to 1 minute. Plug back the power cord to the power source and allow your cable box to reboot.

This simple process will fix minor bugs on your device causing the error. If after resetting your device, you still see the PST error, try any of the steps below.

b. Check For Signal Outage

The next step is to check for a general signal outage. First, how is the weather outside? If the weather outside is fine and clear, that rules out the weather-related outage issue. Visit the Xfinity site or social media handles. If there is a general signal outage as a result of technicalities, Xfinity will always update subscribers on their site.

c. Check For Damaged Cables

Check the cable connected to and from your cable box for worn-out and damaged cables. If you discover a damaged cable, the only option available is to replace the cable with a new cable. Cables are usually not expensive and can be gotten for $10 or less on Amazon.

d. Remove Splitter Connection

If you have a Splitter device or cable connected, remove it and try again.
