1. The first step that you may want to take is to make sure that your Samsung QN85B or Samsung QN90B is securely plugged into the power outlet as a loose connection may not be enough to power your Neo QLED.

2. You should also check for any potential damage on the power cable.

3. Furthermore, there is a possibility that the power outlet you are using may be damaged. In this case, you can try using a different power outlet.

4. If your TV still isn’t turning on after you make sure that it is connected properly to the power outlet, then the next step you can take is to try to press the power button that is located directly on the screen.

If the TV turns on, then you issue may be related to the TV remote. In this case, make sure that the remote has power and is able to communicate with your QN85B or QN90B. We recommend that you remove any physical objects that may be blocking the line of sight between the remote and television screen.

5. If you are trying to watch something or play a videogame from a connected device, then you should make sure that the device is turned on.

6. If you are using the One Connect Box, then make sure that it is properly connected to your QN85B or QN90B.

7. You can also try disconnecting any HDMI cables and then try to turn on your TV.

8. If none of the aforementioned potential solutions helped with powering on your QN85B or QN90B, then we recommend contacting Samsung for additional support.

If your TV is not powering on due to a hardware issue, then you may need to send it in to get repaired or replaced.
