nsa 320 start very hard

[cipnas]

Hello,
I have an nsa 320, aprox. 3 years old. After power failure it restart automatically and all the leds are lit(not blinking). sistem led is orange, hdd leds are red, usb led green and copy led is red. I disconnected from power and connected again, press the power button and the same thing it happens. Only after many (more then 10) repetitions of this procedure it starts.
I tried the usb recovery method, connect the serial cable dont see anything( or i do not make the correct procedure). it appears to be a power supply problem, or an component from the board responsible whit power supply the components.
please give me an idea. thank you.
