HP 8920A BOOT problem

 

Hello everyone.
?
No beeps after boot (Manual says bad Host DCU Controller Board), just some white noise on speaker.
No led lighting on DCU (left corner 4 leds all dark) at all (Manual says DCU or Memory Bd).
The FAN work.
?
Have you ever encountered the same problem?
 

It happens to me too, same problem.
I've never investigated.
Maurizio?
 

Hi Maurizio
How did you solve this problem.
 

Hi.
unfortunately I haven't tried to solve the problem yet due to lack of time.
I hope for some response to your appeal :-)
Maurizio
 

Now I can confirm that the problem is on the A7DCU motherboard. I used 8922 motherboard installed on it and was able to boot up.
