Black screen. no fans.
iMac Intel 20 inch EMC 2133 and 2210
Hey guys.
So i just got an old Imac 20" from 2007 and i just put in a new PSU and the 1 Led is ON. But i cant get light into the 3 others. I can hear the HDD go and the PSU humming very low. If i put a USB mouse in there is light in it. but my fans dont start. i got no picture ( just black ) i can hear the Cd case starts. Can someone help me ? do i really have to get a new Logic board :/ ?
Is this a good question?

Any luck with it? I have an A1224 that turns on LED 1,2,3 are on but no fan or display. The disk and turns on but keyboard does work. Seems it is failing to POST but since LED 1,2,3 are on; not sure what is the problem. I have checked the following using parts from a working iMac of the same kind:
1. LCD fine.
2. Graphic card fine.
3. Wifi/Bluetooth fine.
4. Power supply fine.
5. internal wiring fine.
6. Inverter is fine.
7. Fans are fine.
Any ideas?
