To achieve the most efficiency and success in the upcoming troubleshooting guide, follow the chronological order of our methods and do not skip solutions.
In addition, test your cable box after each fix attempt to determine if the STBH-3804 error code is still there!
Here’s how to fix the STBH-3804 error code in easy solutions:
Solution #1 Power Reset the Cable Box
The very first solution involves performing a power circulation of your Spectrum setup, therefore we are going to discharge your cable box.
The point of this method is to allow the cable box to cool down and refresh all services, which in most cases turns out to be helpful.
Here’s how to power-reset your Spectrum cable box:
- Press the Power Button on the Spectrum cable box to shut it down.
- Disconnect the power cable from the device.
- Wait for 4-5 minutes while the adapter is disconnected.
- Plug the power cable back into the device.
- Turn on the cable box.
- Determine if the STBH-3804 error code is still going to occur.
Note: The longer you keep the receiver unplugged, the more it will cool down!
Solution #2 Turn on Different Broadcast
Chances are that the broadcast you’re attempting to watch on your cable box is corrupted or has lost signal.
Your next step is to switch multiple different broadcasts on your device and determine if the error is still going to occur!
- Simply press the channel buttons to switch broadcasts!
Don’t test on different episodes from the same show, instead test several different titles to determine where the problem is coming from.
The average time it takes for the STBH error to appear is about 20-30 seconds.
To verify that the error code is enveloping only certain channels, go through broadcasts that aren’t linked to each other.
Solution #3 Reconnect the Receiver’s Coax
One of the reasons that your Spectrum cable box is displaying an STBH error is due to a bad or missing signal.
The best way to resolve this problem is to reconnect your cable box’s Coaxial cable, which will refresh the signal that is reaching the device.
- Disconnect the Coax cable for the Spectrum receiver for 60 seconds!
This is the average time taken for the cable box to re-acquire the signal, but for best effects, keep it unplugged for longer.
Some say that unplugging their cable for 10-15 minutes boosted the signal enough for the STBH-3804 error to disappear! It’s up to you.
Note: When reconnecting the Coax cable, make sure to secure it properly on both sides!
Solution #4 Fix Cable Box Power Issues
If your Spectrum cable box is running into some power issues, it would only be reasonable for a variety of errors to occur.
The power struggle is something that greatly impacts devices (especially ones that work with signals) and the problems must be taken care of ASAP.
Here’s how to fix cable box power issues!
- Reconnect the Power cable into the source tightly
- Plug the cable box into an alternative wall outlet
- Unplug the cable box from the power strip/divider devices
- Get a new power adapter for your Spectrum cable box
Tip: Wait for at least an hour, in case there was a recent power outage!
Solution #5 Use a Different TV HDMI Port
As you probably know, your Spectrum cable box connects with the TV via HDMI cable.
Although it is unlikely, some STBH errors could occur due to a faulty connection with the TV.
What you should do next, is plug the cable box into a different HDMI port on your TV.
Here’s how to reconfigure your cable box’s HDMI setup:
- Head to the back of your TV.
- Locate the cable box’s HDMI.
- Unplug the HDMI cable.
- Find another suitable HDMI port to connect the cable in.
- Secure the cable into the new port.
- Get your TV’s remote and change the sources to the new HDMI port.
- Check if the error would still occur.
Note: You will have to browse several broadcasts in order to check if the error is still there.
Solution #6 Replace the Coax Cable
If nothing worked so far, then probably the Coax cable in your setup has already reached its end-life.
Walking out from that, it is time to get the coaxial cable replaced with a brand new unit to solve the STBH-3804 error code for good.
- You can simply order a new Coaxial cable from Amazon.com!
Once you have the new cable, here’s how to replace it:
- Unplug the current Coaxial cable from both ends.
- Get rid of the old Coaxial cable.
- Plug the new Coax into the wall port first.
- Secure the other end of the coaxial cable into your cable box’s port.
- Attempt to stream Spectrum content.
Alert: It may take a few minutes for your cable box to start acquiring a signal from the cable!
Solution #7 Reset the Cable Box
If nothing worked so far, then we strongly suggest performing a Factory Reset on your cable box.
This is our most powerful method so far and but it comes with a cost.
The factory reset is going to erase all contents from your cable box, including settings and configurations.
To factory reset your cable box, press and hold the reset button for 10 seconds!
You can find the factory reset button on the back panel of the cable box. Give it a press for around 10-15 seconds and wait for the cable box to reboot.
It should take the device an average of 3-5 minutes to undergo the reset process and to come back online!
Notice: Do not turn off or unplug the cable box while the reset is ongoing!
Thus, to fix the STBH-3804 error code on Spectrum, perform a power reset on the cable box and turn on a different channel. Next up, fix power issues with the device and use a different HDMI port on the TV. Finally, reset the cable box and replace the coax cable.
