Hi all,
Got a 27 2011 iMac that wont boot. In the beginning, when connected to power, the LED #1 was lit and it went off after pressing the power button. I removed the MoBo battery, did SMC reset and now, when plugging the power cable LED #1 lits for a second and then goes off.
Checked with two other different PSUs - same thing.
Checked the MoBo with everything disconnected except PSU - same thing.
Till now have checked PP12V_G3H, PP3V42_G3H in a couple of TPs and adequate voltage is there. Any thoughts what shall I check next?
Edit1: SCM_RESET_L is 3.55V so the SMC is not in the Reset mode...
Thanks in advance,
Tom
