iMac Not Powering On; all 3 LEDs are unlit

crwdns2934249:0crwdne2934249:0:

Hi!

I have a late 2006 iMac "Core 2 Duo" 2.16 20-Inch (A1207; last of white plastic models). It's been fine until today, but is suddenly powered off and won't turn on--no noise, lights, fans…nada.

I've:

- reset the SMC

- tried different power cords and outlets

- removed and reseated RAM

- opened it: none of 3 diagnostic LED lights are lit

At this point I'm assuming it's the power supply, but wanted to make sure before I buy another. Thanks!
