- Mistakes in Connection
- Momentary Issues on Hisense TV
- Damaged Wires
- Problems With the HDMI Port
- CEC Device Issue
- Remote Control is Impaired
- Software Errors
For the above-mentioned factors, I have mentioned appropriate troubleshooting methods after elaborating on how they have made an impact on this issue.
Mistakes in Connection
The first thing you have to check when your Hisense TV’s CEC function doesn’t work is the connection. Because if there is a loose connection, then the HDMI CEC device will be non functioning and the TV also can’t detect it when trying for a connection. Moreover, you can utilize the CEC feature only if the connection is made with the appropriate input source. If not, then problems as such will happen for sure.
Solution: Ensure Firm Connection, Change the Source
Make Connection Properly:
Go near to the HDMI port of your Hisense TV. Check whether the HDMI cable of the CEC device is completely into it. Suppose it is halfway out, then remove the cable completely once and reinsert it well. After this, you can go to Settings and initiate the HDMI CEC connection, which will turn out successful now.
Change Input Source:
Suppose the connection is fine yet you can’t establish the HDMI CEC connection, then check which input port of the Hisense TV you have affixed the CEC device’s HDMI cable. If you want to avail the CEC feature, you have to make a connection in the input port named eARC. This would be mostly the HDMI 3 or HDMI 4 port. Suppose the CEC device is not connected to this specific port, then rewamp it and try again.
Momentary Issues on Hisense TV
In most scenarios, the HDMI CEC feature is not working because some unexplainable issues have occurred with your Hisense TV. This is due to the activity of bugs or the occurrence of glitches. But you can take a breather as it is just a temporary problem. You can get rid of it with some basic troubleshooting practices.
Solution: Restart Your Hisense Smart TV
When you assume the HDMI CEC function is not working, the issue is at the basic level, then there is no better troubleshooting to try than restarting Hisense TV to fix it. Find the Power button of your Hisense TV in the unit. Long press it for about 5 seconds, and the TV will start rebooting. Otherwise, go to the Settings menu and select the Restart option. When the TV boots up after restarting, the HDMI CEC function will probably work fine.
Damaged Wires
If the HDMI cables on the connection are damaged, then the HDMI device is actually not working, or it is on & off. So, obviously, the HDMI device isn’t active now on your Hisense TV, and that’s why the CEC function is greyed out or not working. Even such a small factor can make you think of big scenarios if unnoticed. So, pay attention to this, too, without fail.
Solution: Repair/Replace the HDMI Cable
Unplug the participating HDMI cable of the HDMI device connected to your Hisense TV. Inspect it thoroughly, top to bottom, and look for any cracks, insulation damage, and any kind of damage like this. Most importantly, inspect the pins and shake them to check to see if it is impaired. If you notice any such damages, then repair it either with a professional’s help or by yourself if you have the knowledge and necessary tools.
Mostly, damage to the wires can’t be repaired. So, better get a new HDMI cable from the Amazon website and use it for connection. With a good condition wire, the HDMI device will function normally with the Hisense Smart TV, as does the CEC function.
Problems With the HDMI Port
Sometimes, the HDMI port involved in the HDMI CEC connection of your Hisense TV might probably get corrupted. Due to this, you are unable to access the function. Moreover, it may be that the HDMI device connected to itself isn’t active on the Hisense TV. This happens when the TV gets shut down unexpectedly or after performing a software update.
Otherwise, the eARC port itself might have been damaged and be unable to allow access to the CEC feature. So, you have to troubleshoot the HDMI ports of your Hisense TV, in particular, to eradicate issues in it.

Reset HDMI Port:
You can reset the HDMI port and get rid of the CEC not working problem on your Hisense TV. To do so, first, turn off your Hisense TV. Then, reach its back or side and go near the connected HDMI cables. Start removing them one by one completely. After that, turn on the Hisense TV and use it for a while. Then, shut it down again and make the HDMI connection back. The problematic HDMI ports on the Hisense TV are now reset, and you can boot them up and proceed to CEC function usage without errors.

CEC Device Issue

If there is no such issue, then proceed to consider the upcoming factor.
Remote Control is Impaired
If you have already set up the CEC function and are using it on your Hisense TV but suddenly can’t access it with the usual remote all of a sudden, then the remote control must be the one that has gone faulty. If this is the case, then you are a bit lucky and easily sort out the issue.
Solution: Change Batteries, Reset Remote Control
Change Remote Batteries:
Turn the remote control to its backside and open the battery compartment. Check whether the batteries are fresh. If they are old, then get a new set of remote batteries from the Amazon website and insert them into the remote. After that, you can access the CEC feature as always.
Reset Remote Control:
Suppose the batteries are in good condition, then the remote should be having a problem. To clear this up, reset your Hisense TV remote in an OS-specific way. You should also make sure the remote control is damage-free. If it is impaired, then you have no other option than repairing it for further access. Otherwise, you can get a new remote control for Hisense TV from Amazon and pair it to use the CEC function without hurdles.
Software Errors
If you have reached this heading, then you might have tried all the troubleshooting methods you have gone through so far, unfortunately, to no avail. So, there should be problems in the software aspect of Hisense TV. Or else, it should be running old software fire that is potent enough to bring up such an issue.
Likewise, you can’t always blame your Hisense Smart TV if the CEC function is malfunctioning. The participating external device is also equally responsible for this. It can also have similar problems to those that your Hisense TV undergoes. So, you should have that too in mind.
