Hi everyone, I have an issue with my imac pro. It doesn't start anymore.
I have no leds light on motherboard. I already changed power supply but same thing. Thank you for your help.

Je me suis rendu compte qu'il y avait un bouton sous les leds sur lequel il faut appuyer pour avoir l'état.
Seul la première led s'allume. J'ai également essayé de me connecter en DFU et j'y arrive par contre j'ai une erreur quand j'essaie de restaurer.
Ist dies eine gute Frage?

I have the same issue. Power supply is good, power does come in to the power supply but the LEDS are out.

Under and to the right of the leds is a push button. The leds will not enable unless this button is pressed.

Yo estoy en la misma situación, si alguien puede facilitarme el esquema de conexionado y de tensiones se lo agradecería.

We have limited information on the iMac Pro system. Here’s a deeper view internally iMac Pro Teardown.
Sadly I never was able to locate schematics and board view drawings for this system. With the logic board number (820-00967) you might google it to see if your luck is any better than I had. I was only able to find this 820-0067 Component Identify thread which offers a link to the schematic but it’s damaged.
I would start off making sure the power cord and power supply are good. As most of the failures are due to power surges or lightning strikes. There are a few onboard diagnostic LED’s you do need to press the small orange button just below the five LED’s.
