1 My iMac doesnt start - Black screen
iMac 27" EMC2546
Hello!
I have a big problem with my iMac.
I can´t start the iMac - there is no gong, fan or something else. Always black screen.
These things i have already done:
- SMC reset
- cleaning the fan
- change the power supply
- change the battery on the logic board
Now i dont have any ideas, what i can do.
I don´t hav a garranty for the iMac - it is from 2013.
If anybody have a idea, please let me know!
kindest regards
Klaus
Did you solve your problem? I have the same problem except that I can hear the gong.
