Nintendo Switch is no longer working, can anyone

I have a question. Ever since I own my Nintendo Switch, it hasn't loaded properly. The battery indicator is on the top left but otherwise I have a black picture. Reset did not work, loud and quieter button then pressed power button, everything does not work. Directly via the electricity, via the power bank, on the PC. Everything does not work.

I saw a key combination on the Internet a long time ago with which I got it once. Maybe someone knows?

If you haven't been charging right from the start, why didn't you complain? Doesn't it load at all, or only very slowly?

Hold down the power button for 12 seconds.

I got it as a gift, so I couldn't complain. But have already found a solution, thanks.

If someone has the same problem:

Switch off the switch completely, do not go into standby mode

Press and hold the volume down button, then press and hold the power button

While you continue to hold down the power button, release the volume down button and hold the volume up button (continue together with the power button)

Release the power button while continuing to hold the volume up button until safe mode starts

I found it on another page.
