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.

For part 2), it may be the bootstrap (KSTART) cap, it may be out of tolerance. You'll have to troubleshoot a little more when the amp is down.
Hope this helps!

You may have to wait until the amp(s) break down before delving further in. Also, get in contact with your local Crown authorized dealer or service center.
(Did you implement the latest firmware updates?)

As for ungrounded equipment: PLEASE PLEASE make sure your [rack] system is properly grounded! If you can get shocks, there is now potential of lethal dosage! I have heard of musicians (guitar players) getting shocked through a faulty PA (mics were grounded to the wrong side of the AC supply) and dying on stage! Just beware!
And yes, it is now possible that the electric circuit may be involved in your faults! The grounding may not be an issue: the electrical wiring may be the issue! Of course, the grounding too. Why is the electrical system not grounded?
A possible problem is current starvation from the AC power supply: the SMPS needs at a minimum perhaps 90 to 100VAC of AC power supply voltage; If the outlet doesn't permit the power requirement for the amps then they will get starved out.
Hope this helps!

Version 184.108.40.206 is availble with SA3.4; It may have been made available for the '02 models, my bad.

Take a look at the first entry, 'Firmware updates for older XTi amps', located as the first FAQ in the Forum lists. It has an executable to load older XTI firmware. Hope this works!
Hey Carminati, Did you get your grounding and electrical issues resolved?
