What you'll notice
One specific HDMI port shows "no signal" while other ports work fine with the same or a different device.
Why it happens
A failed or damaged HDMI port, a broken solder joint on the mainboard, or corrosion inside the port.
How we fix it
We test the port with a known-good source and cable to confirm the fault sits with the TV, then re-solder or replace the port.
Still not working?
If the checks above haven't restored your hdmi ports & connectors, this usually needs a technician. Our HDMI Port Repair service covers exactly this fault.
