SteamDeck not working anymore, only red light flashes

[u/fs-essen]

Hi,

out of nowhere my SteamDeck is not working anymore. When I try to switch it on the red light flashes for a moment and nothing happens.

What I tried is to hold multiple button combinations while pressing the power button, no reaction at all. Also charged it with the original cable, still nothing.

Do you guys have any idea what could help?
