No boot, LED1 on with LED2 flash

crwdns2934249:0crwdne2934249:0:

My 20" imac won't boot up. I started to swap the power supply, but noticed that the logic board LED1 is on. Every 4 seconds it will flash with LED2 and then both off. So the pattern below.

LED 1 for 3 seconds

LED 1&2 Flash

off

Any ideas? I have looked for LED codes for this model, but not finding anything.

Thanks
