iMac Blackscreen

Hi everyone,


I got in struggle with my iMac (late 2015). Software = Big Sur. After an Update the iMac turned off and didn't get alive so far. Blackscreen all the way.


After pressing the start button the fans start to blow, after about 5 seconds it turns off and turns on again.

Now its running endlessly in this state.


I tried to get the RAM in and out, boot with no RAM to try if there is any error screen. No surprise there was nothing.

It would be nice if you have any ideas


Thank you for your help.

Fabian
