Technical Support DAG7BFMB8D0 No Video

[lazaro089]

I have this board. It does turn on but no video output (power led turns on). After a short while (10 seconds or so) it restarts.
The processor is a Ryzen. No datasheet or boardview available.

I measured with Digital multimeter what I think are cpu coils (close to cpu) There are 2 big coils with 6ohm to ground and a tiny one with 7.8 Ohms.

I'll post a picture with some voltage and resistance readings. I hope you can help me with this repair.

I haven't programmed BIOS yet, I was troubleshooting voltages first. Some voltages seem odd doesn't they?

Voltages are normal. The problem can be in the BIOS or RAM or LCD or image flat or CPU which should be checked.
