Hello
I received 27" iMac, Late 2015 model that's broken. I don't know what exactly happened but it appears to be unopened and there are no marks indicating prior repair attempts.
Initially it didn't display anything on the screen and backlight didn't work. Only 2 diagnostic LEDs would light up and 3rd was very faint. I opened it and found F4400 fuse near eDP connector to be blown. Replaced it with a suitable part and backlight came back to life. Unfortunately it still doesn't display anything on the screen. Now I get 4 green diagnostic LEDs.
I can hear the chime... -

When I removed the screen from the iMac to check the status of the LEDs, I noticed that none of them were lit. I had a perfectly compatible and working power supply, so I tried it right away, but the problem remained the same (no LEDs). With the thermal camera, I noticed only a slight warming (32 degrees) of the NCP1605BG chip on the power supply. The rest was completely... -
Hi there
An iMac A1418 late 2013 (but same problem on an A1419 too).
It works but very slow. Fan start to run after few second you turn on the iMac.
I've spoke with a friend in Apple, and he tell me about a sensor defective, but they usually replace the motherboard to fix the problem.
This iMac have no sensor (only one on the display), so I presume he means about a sensor on the motherboard.
Anyone have same problem? any idea about to solve?
Thanks and best regards.
