Re: Imac model 2017 is complely dead No light-12v is ok-ps is changed




Thank you very much for your answer. I did some basic checks before opening the motherboard, such as checking the battery or USB socket and other connections. And any chemicals, etc. have been checked on the board. Unfortunately, my schematic is only 87 pages and I do not know what you are using. Please upload that schematic for me here ... I am also a schematic of iMac. I uploaded myself in the previous post .... Thanks anyway...

Hello everyone

IMac model 2017 intel i5 Completely died after updating the operating system , no lights are on the board. I changed the power supply before just to gain experience, but again the problem has not been solved .. I have done a lot of research about it ...
I checked the SMC U5000 and pp3v3 pp5v. If you look at the schematic, the first light is called le0301 with the abbreviation in pp3v3 S5 circuit. before this I get 12 volts, 5 volts and 3 volts in U7600 well. but after U7600 and before reaching LED1_S5 everything is cut off . I reflowed the u5000 with a temperature...

I have the same problem. The Mac is completely dead. No lights on the board are on. I used to think it was from the power supply. I changed the power but still the same problem. I have a 12 volt input.
