Samsung TV only shows a red LED light and does not turn on.

Hello, Diogo how are you?

Restore the product settings and observe, follow the instructions below on how to restore:

Press the SOURCE button on the remote control and select TV Mode.
Then, press the EXIT key for at least 15 seconds and select Restore > OK.
The television will be turned off automatically, turn on the product and perform the requested settings on the screen.
observe if it will be normalized.

Also check if the power cable is firmly connected to the back of the television.

Hugs!

Hello Diogo,

All good?

The problem may be occurring due to the power source; in this case, I recommend that you perform the test on
other outlets without using a power strip. After, reset the device as follows:

1- Press and hold the EXIT button on your remote control until a message appears asking if
do you want to restore everything to default values;

2- Select the ok option;

The television will turn off;
4- Unplug the television and plug it back in after 2 minutes;
5- Make the settings that it will request (Plug and Play).

Hugs!
