Why is Hisense TV HDMI port showing Weak/No Signal?

“Weak or No Signal” error on a Hisense TV’s HDMI port can be caused by various factors, including hardware and software-related faults.

Before you jump to conclusions, try the most obvious solution first – power cycling the TV.

Simply unplug the TV and hold down the physical power button for at least 15 seconds. Then, wait for a few minutes before plugging it back in.

If it doesn’t resolve the issue. check out the following methods:

  1. Check the HDMI connections: Ensure that the HDMI cable is securely connected to both the TV and the external device. Try using a different HDMI cable to rule out a faulty cable.
  2. Adjust the HDMI format: Some users on different forums have reported issues with the TV’s HDMI signal when using the Enhanced Format HDMI mode. So, try switching to Standard Format HDMI mode in the TV settings to see if it resolves the issue.
  3. Update the TV firmware: Ensure that your Hisense TV has the latest firmware installed. Check for any available updates and install them as needed.

Additionally, if you are using HDMI ARC (Audio Return Channel) to connect your TV to a soundbar or receiver, make sure both devices support HDMI ARC and have it enabled in their settings.

And oh, make sure to test with the different HDMI ports.

Hope this helps…
