Quick checks

1. Restart the device: unplug power for 30 seconds, then reconnect.
2. Reconnect the cables, using the ones that came in the box.
3. Update the firmware. How

No signal or wrong input

• Select the input the video bar or PC is connected to.
• Reseat the HDMI cable at both ends and try a certified high-speed cable; long runs may need an active cable or extender.
• Make sure the source is awake and outputting a resolution the display supports.
• Disable HDMI-CEC on one end if the display keeps switching inputs or turning off.

Touch not working

• Connect the touch USB cable from the display to the same computer that sends the HDMI signal.
• Recalibrate touch from the display's settings menu.
• Update the display firmware.

Won't turn on or status light is red/blinking

• Check the power adapter is the original one and firmly connected, and try another outlet.
• Unplug for 30 seconds and power it back on.
• Check the status light meaning in the user guide; a blinking light during startup or updates is often normal.
• If it never finishes starting, contact the manufacturer's support for a recovery.

When to contact Samsung
