To preface it's been a great day and a horrible day. Got my 15" non retina MBP i7 in today. w00t w00t. Now onto the bad. Apparently I overloaded the electrical in the "office" room and blew a fuse. So I go to reset the breaker and come back into the room to fire up the iMac (Mid 2010 EMC 2389). Won't power on. Hmm...start trouble shooting. Reset SMC, PRAM, leave unplugged for copious amounts of time, plug back in, nothing. No sound, no beeps, nothing. Tried using your run of the mill (known to be a good one) PSU cord and still nothing. Removed the two 4GB Cruicial sticks and left the stock 4GB of RAM in, nothing. The one thing I haven't done is check the diagnostic LED's. I'm thinking I don't need to at this point. I don't mind being hands on, so I'm going to probably be buying a PSU from iFixit and taking the gamble hoping that's the issue. I'm guessing when I went to reset the breaker, a power surge happened and fried it. It was plugged into a surge protector but I see that didn't help any. What do you guys think?
