The HDMI error on your Hisense Tv means the television is not receiving a video signal from the device connected to its HDMI port. Fix hint: this is almost always a cable, input selection, or source device issue rather than a fault with the TV itself.

What the HDMI error means

When your Hisense TV shows “No Signal” on an HDMI input, it means the screen is on and working, but it cannot detect a valid data stream from whatever is plugged into that port — a cable box, games console, laptop, or streaming stick. The TV itself hasn’t broken; it’s simply waiting for a signal that isn’t arriving. This is one of the most common issues reported alongside other Hisense Tv ERROR Error Code: Causes and Fixes.

The cause is usually external: a loose cable, the wrong input selected, or the connected device being switched off or in standby. In rarer cases it points to a faulty HDMI port or cable.

Common causes

  • HDMI cable is loose, damaged, or not fully pushed into the port
  • Wrong HDMI input selected on the TV’s source menu
  • Connected device (console, box, laptop) is powered off or in sleep mode
  • Faulty or low-quality HDMI cable that can’t carry a stable signal
  • HDMI port on the TV or source device is damaged or worn
  • Source device output resolution isn’t supported by the TV

How to fix the HDMI error

  1. Check the source device is on: Make sure the console, box, or player connected to the HDMI port is powered on and not in standby.
  2. Reseat the HDMI cable: Unplug the cable from both the TV and the device, check for bent pins, then push it back in firmly on both ends.
  3. Confirm the correct input: Use the Source or Input button on your remote to cycle through HDMI 1, 2, 3, etc., and select the one matching your device.
  4. Try a different HDMI port and cable: Swap to another HDMI input on the TV, and test with a different cable to rule out a faulty lead or port.
  5. Restart both devices: Unplug the TV and the source device from the mains for 30 seconds, then plug back in and power up again.
  6. Check resolution settings: If the source device allows manual output settings, lower the resolution or refresh rate to a standard setting like 1080p 60Hz and see if the signal appears.

FAQ

Why does my Hisense TV say No Signal even though everything is plugged in?
A. The cable may look connected but not be seated properly, the wrong HDMI input may be selected, or the source device could be off or asleep. Working through each connection point usually finds the fault.

Can a bad HDMI cable really cause this error?
A. Yes. Damaged, bent, or cheap cables often fail to carry a stable signal, especially with high-resolution content, and are one of the most common causes of this error.

Should I worry this means my TV is broken?
A. Not usually. The HDMI no signal error is almost always caused by something outside the TV — the cable, input selection, or connected device — rather than an internal fault.
