How can I fix my black screen of death?

Hello Eric, this is Manuela!. I'm an Independent Advisor and community user like you ready to assist with this.

May I know if this happens even after using a different power cable or a socket/connecting the console in another room?

Have you tried some of these fixes here instead, some people have had luck with them.
