Samsung TV error 116 can appear in two related contexts: prompting a required software update, or flagging an HDMI connection problem, depending on the specific model and firmware version. Both scenarios point to compatibility issues that need addressing.
What Causes Error 116
Outdated firmware unable to properly recognise connected HDMI devices, such as a new soundbar or streaming stick, is the most common cause of the HDMI variant of this error. On the update side, the TV may detect that its current firmware version is incompatible with a newly connected device or app, prompting a mandatory update before continuing. Damaged or low-quality HDMI cables that cannot maintain a stable handshake with connected devices can also trigger this error. In some cases, an HDMI port itself has failed, particularly on TVs with heavy multi-device usage.
How to Fix Error 116
Update your TV's firmware immediately through Settings > Support > Software Update, as this resolves the majority of compatibility-related Samsung TV error 116 cases. If the error is HDMI-specific, try a different HDMI cable, preferably a high-speed certified cable, and test the connected device on a different HDMI port. Restarting both the TV and the connected HDMI device, such as a games console or streaming stick, resets the connection handshake. If the error persists on one specific port only, that port likely has a hardware fault requiring professional inspection.

Frequently Asked Questions
- Do I have to update my firmware to fix this error? In most cases, yes, as this error is often specifically triggered by outdated firmware failing to recognise connected devices.
- Can a cheap HDMI cable cause this error? Yes, low-quality or damaged cables can fail to maintain the stable connection needed for proper device recognition.
- Why does this error only happen on one HDMI port? This usually points to a hardware fault specific to that port, rather than a general firmware issue.
- Is it safe to update firmware while a device is connected? Yes, though it is good practice to complete the update first before reconnecting external devices.
- Will unplugging the connected device help? Yes, unplugging and reconnecting the HDMI device often resets the handshake and resolves temporary errors.
