Proceed HPA2 blinking.

In need of help.

I have a Proceed HPA2 amplifier.
The power indicator light (yellow color) is
blinking.
The standby light (red color) is completely off.
There is no power going to the speakers
I had the amplifier directly connected to the wall.

I connected the amplifier to another outlet and I
have the same problem.

What could be and what to do?

I would appreciate any help.

Thanks
