Connection Issues

If restarting and power cycling didn’t work out, then there could be a chance of a loose connection if the external device does not show up on the connected input port.

Turn to the rear side, which is the Hisense TV HDMI port location. See if the HDMI cable of your streaming device is fully affixed to the HDMI port. If the cable is halfway out, insert it fully into the HDMI port and tighten the connection. You can also remove the HDMI cable completely and insert it back into the HDMI port freshly to ensure a stable connection.

Damages in HDMI Port/Cable

It is time for you to dive into some deep analysis hereafter if all the above-mentioned guidances failed to fix the HDMI not working issue on Hisense TV. To begin with, you have to check the condition of the HDMI cable you are using to connect the external device to the Hisense TV. The same applies to your Hisense TV HDMI ports. If they are damaged, you can’t expect anything but an HDMI not working problem.

Solution: Repair Damages and Clean HDMI Ports/Cable

Check for Damages on HDMI Port & Cable:

First, remove the HDMI cable of the connected device from the respective HDMI port on Hisense TV. Then, thoroughly inspect the cable first. Make sure there is no insulation damage, bird caging, or heat damage present. Shake the connectors and see whether it is jolting. If any such damages exist, you have to repair them. However, it is better to purchase a new HDMI cable from the Amazon website and make a connection using it. This will ensure that no connection-wise error happens for quite a while for the Hisense TV HDMI function.

If the HDMI cable is in the correct shape, then you have to shift your attention towards the HDMI port. Like the former, your Hisense TV’s HDMI port is also prone to damage. The different types of damage that can occur include connector socket area breakage, pins getting bent/melted, or total disintegration of the port.

So, look for any of these damages. If you notice anything, then you have to repair it with the help of professional repairmen. Until then, you can access the external device by connecting it to any other HDMI port if it works on your Hisense TV.

Clean Hisense TV HDMI Port & Cable:

Likewise, clean the interior of your HDMI cable connectors gently with cotton earbuds. There is a chance that your Hisense TV HDMI function will work fine after cleaning.

Problems with the HDMI Device

You can’t always suspect your Hisense TV alone if HDMI is not working since an external device is also involved in this case. Because if no ports of your Hisense TV does not recognize the device, then it may be problematic.

Solution: Check the HDMI Device’s Normalcy

If you have any other HDMI-based device, connect it to your Hisense TV and try to access it. Suppose it works, then link the former device to the same port and see what happens. If this one doesn’t work, then this particular external device is going through some issues. Maybe it could have a hardware impairment. So, you’d better take it to a nearby service center and repair it. After the service, you can affix it with Hisense TV and access its holdings.

Incompatible HDMI Format

Hisense TVs have specifications for compatibility with HDMI connections. Any particular model can’t accommodate an HDMI device whose specification is beyond its maximum compatibility.

Solution: Check the HDMI Specification of Device

First, check the HDMI specifications of your external device. Then, connect it to the HDMI port on Hisense TV that has the exact or higher specification. To say in short, if a Hiense TV HDMI port supports HDMI 2.0, it can’t accommodate HDMI 2.1 specified devices but can access HDMI 1.4 devices.

This issue mainly occurs for users opting for 4K streaming. So, pay attention to this and make a connection appropriately on the HDMI 2.1 port on the Hisense TV. In the same manner, if the Hisense TV HDMI ARC is not working, check whether you are using a cable with a minimum of HDMI 1.4 specification. Make sure you connect it to the ARC or eARC port and change the audio output on Hisense TV to ARC on-screen later.

HDMI Function is Corrupted

There is a chance that the HDMI function will be fully corrupted if none of the Hisense TV inputs work. So, you should target it and implement some troubleshooting measures to fix it.

Resetting the HDMI ports of Hisense TV is a simple process. Turn off the TV and remove all the connected cords from the HDMI port one by one. Later, boot up the TV and use it without HDMI connections for a while. After 15 minutes, turn off and make an HDMI connection again, and it’s all done.

Old Firmware on Hisense TV

If you have cross-checked the possibility of the above factors and none of them are responsible for the HDMI not working problem on your Hisense TV, then maybe the real influencer is not very threatening. You should be using the TV for a long without updating. Due to this, the firmware has turned buggy and corrupted its cache. This has resulted in HDMI failure on your Hisense TV.

You have to update your Hisense TV to eradicate the problematic bugs and glut cache that are causing the HDMI function not to work. Press the Cogwheel button on the remote and launch the Quick Settings menu on-screen. Navigate to the System Update option and check the firmware version.

Software Error

Software errors on your Hisense TV are a probable factor for the HDMI not working issue and the extreme scenario that you can fix. So, after trying all the above troubleshooting methods, land on this as a last resort.
