A3000 Boot issues

[alex]

Anyone have any ideas what a rainbow boot screen means?  My A3000 won't boot any longer despite swapping the CIA chips, daughter card, CPU card, and power supply.

The battery is clean and no signs of corrosion.  I've removed all the cards, etc.

Thoughts.

The videos say that is private so we can not see it.

Rainbow boot, I never seen it like that, looks like a test picture.
Can you hold both mouse buttons before power up and turn it ON. Then try to boot w/o startup-sequence.

Sorry.  fixed the youtube from private.

The hard drive was disconnected.

That looks like a monitor test pattern. Are you sure your monitor is good? Can you test with another?

I tried two monitors.  The video is available now, it just keeps cycling through the dark grey, light grey, rainbow, blue, black, then back to grey
