Right.

I've seen the flashing LED before - I had an A2000 board that
was stripped (Zorro sockets, DRAM, etc.) by the local dealer
after it was brought in by a customer who said it was hit by
lightning. I threw it on $25K of diagnostic equipment we used
to build/repair COMBOARDs and went to town. Tracing bus cycles
through the ROM code, it failed a RAM test (yes, I put the RAM
back first ;-) Turns out, the fault in this particular board
(after I ran wires to replace vaporized traces) was a TTL chip
next to the main Xtal. The *input* was pulling down the clock
enough to mess with Agnus. A new 7404 (or whatever it was) and
that problem went away.
A "Green Screen" is the classic Agnus symptom. Problems with
Agnus herself, CHIP RAM or anything that affects the clock
getting to Agnus could be causing the flashing LED error. I
do not know the criteria that differentiate a Green Screen
from an LED flash.

The caps lock LED is only for keyboard errors.
