My A4000T is out to lunch

[Xand]

For me that meant my 4000D died and I put all the cards back in my 3000UXD which is still working.

There is a site somewhere that tells what all the colors mean. Maybe its was AU?

Here are some of them:
RED   : If an error was found in ROMS.
GREEN : Error found in the CHIP RAM.
BLUE  : Error was found in the custom chips.
YELLOW: If 68000 found an error before the error trapping software
        (GURU) was running.
