Dead A3000D - not even the LEDs are turning on!

Its common to have a cracked trace/solder on the led board. check with a meter for power at the motherboard led pins.
Start at the psu connector and trace 5v to the respective chips to see if its making it around the board.
You only need chip ram installed for testing.
some good info on Castellans site(Anthony) http://amiga.serveftp.net/
good luck!

you could use a A520 modulator on the 23pin port to get composite out and maybe run that to a tv or capture card? if u had one with a rca composite jack.  prob not a option either i guess?.
Seen alot of cracked led boards like that.
