                  iMac A1418 - No LED, no power after overvoltage on Ethernet port
                  by ryogadan78
                  Hi guys, I need your help again.
                  I have this iMac from a customer that shut down during a storm along with all the other devices in the house. In particular, the router, connected via Ethernet to the iMac, caught fire.
                  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...

                  iMac M1 DFU restore issue
                  by Stephen
                  iMac turns on no drops no cracks, tried to DFU Restore the iMac, logo turns on great! however iMac turns itself off and then restarts to the (!) icon and won't post the restore. Tried thunderbolt 3 cable, tried regular USB C cable and nothing.

                  this is the message it gives me with the error

                  Unexpected device state 'DFU' expected 'RestoreOS' (Probably forced into DFU mode externally) [com.apple.MobileDevice.MobileRestore – 0xFAE (4014)].


                  Any thoughts what this could be? I will open it up and repair it but I am not 100% sure since this iMac doesn't...

                  iMac 27” 2020 Boot issue
                  by Stephen
                  Customer came in for data recovery, came to find out data is soldered on to this iMac (learn something new everyday) this is a 2020 T2 iMac so I was surprised because the iMac Pro has a T2 chip and it isn’t soldered on. Anyways, the iMac boots to Apple logo and then restarts, before it turns off you hear a quarter fan spin then it repeats itself. I decided to do a DFU revive to restore any hardware firmware issues and it was successful in reviving the device however the issue persists in boot looping. It shows the Apple logo for like 40 seconds then turns off and fan spin rinse repeat. I...

                  APPLE iMac (21.5‐inch, Late 2013) 820-3588-A not turning on, faulty PS?
                  by mexbeb
                  Ciao a tutti! I was given an old late 2013 iMac that doesn't turn on. I have the .brd file and the schematics and I've done a little analysis on the boards. Starting from the PS it appears to have 11.6V instead of 12V and that is a little strange, isn't it? Measured test points for PP12V_G3H and gives me 11.6V as well.

                  The iMac have two different types of behaviour:

                  1) no button pressed when inserting AC cable; inserting AC cable turns LED #1 on, when pressing power button LED #1 turns off for half a second, then turn on again, LED #2 turns on for half a second and...
