Will not boot. No fan noise, screen does not light up.
iMac 12,2 A1312 EMS 2429
Hey guys,
I've got a 2011 iMac. A few years ago I installed a SSD as the main drive and it's been running great with 16GB or Crucial RAM. A few days ago it started with the beach ball while in Photos.app. I left it alone without force closing Photos and the next time I checked in (18+ hours) it was turned off and would not power on. No power. No fan noise, no back light on the screen nothing. So far I have:
- Reset the SMC
- Tried a different outlet
- Tried a different cord
- Unplugged all devices connected to it
- Pulled the RAM and installed Apple RAM
- Opened it up and examined for any gross problems, nothing noted
- Bought a new PSU and replaced it
I examined the troubling shooting LED's and the only that comes on is #1. Currently I have the LCD panel off (the only way to see the LED's) and RAM out.
The only time I can get it to do anything is if I hold the power button for 10 seconds while plugging the power cord in. Then I can get the fans to turn on full blast, but I still only get the #1 LED to light up. Is it the logic board? I don't know what else it could be at this point. I sure hope it's not, but after replacing the PSU I've lost all hope.
Any ideas?

Have you tried powering it up without a hard drive you should get a white screen if nothing else is the problem

The screen or fans don't come on period. And I have two drives connected. The original HDD and a SSD.

So I replaced the CMOS battery, (2032), the PSU and put everything back together, still nothing. No power. With everything connect still only get LED #1 to come on. %#*@.

Did you get this figured out? I'm having the same exact issue.
