Quit working, replaced the power supply and still no luck. What next?
2007 iMac 24" EMC 2134
One day computer failed to start, no lights, no response.
I followed the troubleshooting steps.
I've reset the SMC, the SO DIMM and replaced the power supply.
After replacement when I initially plug it in the #1 LED lights, then briefly 2 and 3 will.
No response to the power button, no lights after 5 seconds.
