CM5 doesnt boot anymore - dead?

#1

Hello!
I use the CM5 with an RPi4 IO Board as Desktop computer. Today I tried to power it on - but it stays powered off. Voltages on the IO Board are correct.
I tried a different IO Board and different SD cards. But sadly nothing. The CM5 is dead.

I tried to measure some of the voltages on different points on the CM5, it seems like the RK806 is not producing any of the needed voltages …

Can someone assist?

Regards
Stefan

Hello!
Yes it was properly working for a few weeks now - was very happy with it (superb for compiling arm64 packages).
Sadly no LED comes on …
I used the Radxa Bookworm CLI image with my own XFCE setup.
