3 Green Leds Tone Restart Black Screen Imac Intel 24 Emc 2134 And 2211
Chosen Solution I have a 24" Mid 2007 A1225 EMC 2134 that gives me a POST tone, 3 LED lights then shuts down and restarts. It then hangs on restart at the 3rd LED. Completely black screen. No signal to external monitor. The hard drive checks out on another machine and has 10.9.1 installed. I am finally just going to pay Apple support to see if I can get a correct answer before buying any parts....
