LED 1 goes off when I press the power button
I have an IMAC 20 Isight and am having starting up problems.
I have opened up my mac and uncovered the 4 LED which are hidden behind the right speaker.
When I connect the power cable to the mac. The 1st LED lights up. But when I press the power button, the 1st LED goes out and none of the others light up. I have reset the SMU and that didnt help.
Does anyone have any idea what it could be.
Hi Mayer, it's not the PSU. I got a replacement PSU and still have the same problem. LED 1 lights up when I connect the power cable. But once I press the power button the LED1 goes out and none of the others lit up. Any suggestions?
