Every source — decoder, streaming box, games console, soundbar — connects through an HDMI port, and with cables plugged and unplugged repeatedly over the TV's life, these ports take real mechanical wear. A port can fail electrically (no signal at all), mechanically (loose, only works at an angle) or partially (signal but no audio, or intermittent dropouts) — and diagnosing which is which decides whether the fix is a re-solder, a full port replacement, or simply a different cable.
Before any repair, we always rule out the cheapest possible causes: a worn cable, HDMI-CEC/ARC settings interfering, or a source device fault rather than the TV itself.

When the hdmi ports & connectors goes wrong
These are the failures we're called to most often — each with its symptoms, causes and our fix on the dedicated problems page:
- No signal on one HDMI input — One specific HDMI port shows "no signal" while other ports work fine with the same or a different device.
- HDMI port loose or only works at an angle — The picture drops out unless the cable is held at a specific angle, or the port visibly wobbles.
- Picture but no sound over HDMI — The image displays correctly but there is no audio from that specific HDMI source.
- Intermittent HDMI dropouts — The picture flickers, drops to black, or shows "no signal" briefly and recovers — worse when the cable is touched.
