If you experience difficulties powering on Samsung Smart TV, the problem might lie with the outlet, cable, remote, or the TV itself. Pay close attention to the red standby light as it indicates important information. Typically, the red standby light remains illuminated when the TV is off and turns off when the TV is in use.
Although it is normal for the red standby light to be on when the TV is off, if the TV still fails to turn on after attempting to do so, there may be an issue with the remote control. To troubleshoot, start by powering on the TV using the power button located on the TV itself, rather than using the remote control.
If the TV turns on without using the remote control, it indicates that the remote control is the problem. You can try replacing the batteries or reach out to our Samsung Care Australia experts at 1300 362 603 for further assistance.
Note: The power button on the TV is typically located underneath the Samsung TV logo, but its exact position may vary depending on your TV model. If you are unsure about its location, refer to your user manual.
To troubleshoot this issue, start by checking functionality of your cable and outlet. First, ensure that all the cables are securely connected. Next, unplug the TV from the power source for 30 seconds. Disconnect any power boards or surge protectors that the TV may be connected to, and when plugging it back in, directly connect it to a working outlet. If the issue persists, try using another outlet.
If the red standby light appears following these steps it indicates that the TV is receiving power and is likely to turn on without any problems. This suggests that there may be an issue with the initial outlet you tried.
If the TV standby light is flashing, it is important to check if you are using surge protectors. Over time, these protectors can wear out and fail to provide sufficient voltage for your TV. If this is the case, consider replacing the surge protectors. A flashing light typically indicates a power-related problem an issue with an internal component of your TV.
