If you use a Mediacom cable box, you know the frustration when you get back home, turn on your TV, and see ‘No Signal’.
You try turning the cable box off and back on, but nothing.
And you’re evening’s probably ruined since you were looking forward to watching a movie or TV show that you follow regularly.
The good news is that it’s most likely a simple fix, and I’m here to help.
Why Is My Mediacom Cable Box Not Working?
Short Answer: Your Mediacom Cable box isn’t working because the coaxial cable is loose, the power supply isn’t working properly, the cable box isn’t connected to the internet, transmission issues, or damaged HDMI cables or ports.
It can also be due to bad weather or maintenance issues. In some cases, you might also have a damaged cable box.
Fix: Mediacom Cable Box Not Working (No Signal)
Let’s work our way through the more simple fixes and then go into replacing failed components.
Method 1- Check The Coaxial Cable
If you are watching cable TV via your Mediacom cable box, make sure the coaxial cable is inserted properly into the back of the cable box.
Sometimes it might not have been seated properly in the first place, and over time it might have disconnected.
Pop it back in and you should be golden.
However, if you still don’t get a signal, the coaxial cable might be damaged and needs to be replaced.
But I’d recommend checking out the other fixes before jumping in and buying a new one, since it could be another issue.
Method 2- Ensure Your Power Cable and Outler Work Properly
Check that the power cable is connected properly to your cable box and to the power outlet.
If the power cable is damaged, you’ll have to replace it. Even if it works, it’s not reliable and can cause further damage down the road.
Additionally, if it’s an issue with the power outlet, get it replaced and use another power outlet temporarily.
You can also use a power strip to connect multiple devices to a single power outlet, but make sure you use a good-quality device.
Method 3- Make Sure You’re Connected To The Internet
If you use the cable box primarily to stream content, then you won’t be able to do that if your internet connection is out.
You need internet to access streaming apps, and without it your cable box is pretty much just a box.
Fix it by restarting your router.
Turn off the router and unplug the power cable. If you use a LAN cable to connect to the cable box, disconnect that as well.
Wait for 30 seconds, plug the cables back in, and power it on.
Once it boots up, you should have access to the internet and the cable box will now be able to stream content.
However, if you still don’t have access to the internet, then you might need to troubleshoot your router or get in touch with support to find out what’s going on with it.
Method 4- Check The HDMI Cables And Ports
After the power cable, this is probably the most important cable, since you won’t get an image on your TV without an HDMI cable.
So make sure it’s connected properly to both your Mediacom cable box and TV.
While you’re at it, check if there’s any damage or fraying on the connectors, as this can prevent the display from working on your TV.
Also, check if there are any bent pins on the HDMI ports of the TV and cable box.
Even if one end is damaged, the display signal won’t pass through.
Replace the cable if necessary, but make sure you pick up a high-speed HDMI cable rather than anything you find off the shelf.
A good HDMI cable will be more robust, provide better image quality, and transmit data at higher speeds.
So if you’re watching live sports which is usually broadcast at 50 fps (frames per second), or gaming at 120 fps, you won’t notice any stutters.
If the HDMI ports are damaged, that’s a different story.
Damage to the HDMI port on the TV is usually fine, since you’ll have at least one or two more HDMI ports. To repair the damaged port, you’ll have to contact an authorized repair shop.
But if the HDMI port on the cable box is damaged, you’ll have to get the cable box replaced by reaching out to Mediacom Support.
And this also brings me back to the coaxial cable I mentioned at the beginning.
If your HDMI is fine, it’s probably the coaxial, and if it’s the coaxial is fine, you need to get a new HDMI.
Method 5- Use The App During Transmission Issues
Transmission issues will either prevent you from watching content altogether or give you a mess of an image that keeps skipping and stuttering.
There’s really no way to fix it by yourself, since it might be due to maintenance work being done in your area.
These outages don’t happen often, and it’s mostly done to make sure that all the transmission equipment is working as is.
And if it’s due to bad weather such as a storm or heavy winds, you can forget about anyone being able to do anything.
However, as long as you have access to the internet, you can still download the Mediacom Xtream app on iOS or Android and watch your content on the go.
It’s available on a multitude of devices, and if your TV supports casting, you can load up the content on your phone or tablet and still watch it on the big screen.
