It is not surprising to find modern Smart TVs, like Insignia Fire TVs, not working once in a while. But channel issues on TVs are always a cause for concern.
Just recently, my Insignia Fire TV had trouble finding cable channels and I had to find a solution for it. I read through several user forums and support pages and found a handful of solutions.
I compiled all the fixes into this troubleshooting guide so that you can fix your Insignia Fire TV if it cannot find cable channels.
If your Insignia Fire TV cannot find cable channels, check whether the cables and ports are working fine. Next, power cycle and update the TV to the latest firmware. You can also deregister and re-register the Fire TV on Amazon. If none of these work, factory reset the Fire TV.
Check the Cables and the Ports on Insignia Fire TV
It is necessary that you use the right cables with the right specifications for your Insignia Fire TV so as to get the best performance from it.
Using faulty cables will increase the chance of risk and damage to your Fire TV. It is necessary to ensure the cables and ports are in proper working condition.
Some of the problems associated with using a faulty cable are Toshiba Fire TV being stuck on loading screen or the Toshiba Fire TV screen flickering.
One of the most important cables for the Insignia Fire TV is the coaxial cable which enables cable transmission.
If you are experiencing fuzzy or pixelated images, then it's most likely time to change this cable.
Also, make sure that your Fire TV is properly powered. Ensure that the power cable is not bent or broken and is in proper working condition.
In addition to these cables, make sure that the TV HDMI cable, USB cable, and ethernet cable are not worn out or broken.
Damage to the HDMI cable, USB cable, or Ethernet cable can result in poor video/audio quality, intermittent connectivity issues, and a slow internet connection among various other problems.
If the connectors or port leads of any of these cables are broken, we suggest you replace them with new ones. Check if the Insignia Fire TV finds cable channels again.
It is also important to ensure that you use the right port for connecting devices to the Insignia Fire TV. Each port has its own set of features and capabilities.
Make sure you are plugging the right cable into the right port. Also, keep the port free from dust and debris.
A broken or damaged port will result in fuzzy or no picture, slow internet speed, and connectivity issues. Check for the cable signal after ensuring all the ports are working.
Recommended cable specifications:
|HDMI CABLE||At least HDMI 1.4 with a bandwidth of 10.2Gbps||To connect a gaming console, soundbar, or Blu-ray player|
|Coaxial cable||RG6 or RG11 cables with a minimum bandwidth of 3GHz||For cable/antenna reception|
|Ethernet cable||Category 5e with at least 100 Mbps bandwidth||To connect the TV to the internet|
|USB cable||At least USB 2.0||To connect external peripherals like a keyboard or mouse|
|Power cable||Select according to the manufacturer's specification based on the TV model||To power up the Fire TV|
Note: Even though these are the recommended cable specifications, the individual cable requirement may vary based on specific TV models. Check your manufacturer guide to know the correct specifications.
Ensure you are using cables from trusted manufacturers that are specifically designed for the Insignia Fire TV. Using generic or third-party cables can potentially damage the TV.
Use Proper HDMI Cables
Using the right HDMI cable is necessary to ensure optimum performance and smooth picture quality.
It is important to make sure that the HDMI cable that you are using does not have any wear and tear. Also, check the cable for any broken leads.
We suggest you use at least an HDMI 1.4 supported cable with bandwidth transmission support of 10.2 Gbps for smooth operation.
HDMI 2.0 or higher is required if you intend to stream 4K ultra HD content.
Some modern cable boxes demand a higher standard HDMI cable, preferably HDMI 2.0 and later. Failing to satisfy this requirement will lead to issues such as Toshiba Fire TV not finding cable channels.
The Insignia Fire TV supports High-bandwidth Digital content protection (HDCP) which is used to prevent unauthorized copying of content.
Make sure that the HDMI cable you are choosing also supports HDCP.
A cable length of 6 to 10 feet is recommended for most setups. Having a longer cable will degrade signal strength and lower the picture quality.
Make sure to use high-quality cables made specifically for the Insignia Fire TV to ensure optimum performance and quality.
