Thanks very much for your help.

I'm going to remove the hashboard and try to turn the machine on.

I'll keep you all posted.

Thanks again

Here you go!

I'm pointing with the pen the damaged component.

Hello All,

I bought a new S9 machine from bitmain. It worked fine for three months but then the machine shut down.

Checking the motherboard, we found that one transistor was damaged.

Does anyone know what the transistor model is in order to replace it?

The transistor is located next to the three capacitors blue and grey?

Thank in advance for your help.
