One of our LB15's just stopped during a cycle. The whole screen was just flashing on and off.(all pixels with jiberish) The CPU shows a cycle error on the status leds. I checked all my voltages going to the main board and everything is fine. Any thoughts?? I'm aiming towards the main board.

This machine has a 5000II main and all we have extra are 5000's. Is there anything I can do to test with one?

We are down with of course a HOT job on the floor... LOL never fails
