CCARMINATI

Hi, I have issues with 5 diferent XTI amps. Before someone asks, amps have been tested outside the rack without any contact with the other amps. The issues I will describe are intermitent and present on some of the amps from time to time or sometimes at all amps at the same time:
1)Amps starts up just fine, but a second before the green light should turn green it turns off (relay clicks before going off).

2)After pressing the power button, the amps screens and input signal leds blink a couple of times like the amp was 'trying to start'; sometimes they do start, other times they shutdown.

As mentioned, it has happened with all, some or none of the amps at any given day.
