One Connect Box: Power Issue
The One Connect box that comes with the 2018 Q7, Q9 and The Frame model TVs are designed to power the TV panel through the One Connect box. Older One Connect boxes required one power cable for the One Connect box, and another power cable for the TV.
With less cables, and the improved design of the 2018 One Connect box, there is a safety limitation built in to ensure that you do not overload the TV when connecting it to power. The One Connect box should be connected to the TV panel before connected to the power.
If you find that your TV will not power on, or shows an abnormal display on setting up, follow the step-by-step guide below to ensure that no damage occurs when connecting the TV to power.
Make sure you hear a 'Tak' sound when connecting the One Connect cable into the back of the TV
To check whether the One Connect box is receiving power, you can take a look at the Optical cable port. There's a red LED behind the port that will light up when the One Connect box is powered. If you have plugged the One Connect box into the power supply but there is no LED lit up, please contact us by Live Chat or call 1800 726786 4 (Toll Free in India) to speak to our Samsung Care experts who can further troubleshoot the power issue.
