Mac Pro 2019 - not MacBook

[Mortentoft]

Hi guys… I really need your help on this Mac Pro 2019 A1991. I’ve never touched something like this… my first time.
this Mac Pro (Sorry i Can not find the board number) is bootlooping… boot sound and shuts down…. Boot chime and shots down… and and and. I do not know where to start. No signs of damage/liquid. Looks like new. Does anybody know where to start? I have no spareparts at all and data is very important.

No schematic available for any Mac Pro.

Try starting in safe mode.
Also test if stays on in target disk mode.

I will try tomorrow… today I left the building. I will let you know how it went.

Hi’ 2informaticos. It boots into safemode but as soon it starts ssd it breaks down again… Maybe i am loucky to save data through target disk. That is my project tomorrow. Thank you for your good idea

Hi’ 2informaticos. I solved it. Got a “loaner” powersupply and now it boots normal. Why? I do not know. I have ordered a new one from Apple - about 500$. Thank you for your time on this
