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 of 405 degrees and I do not think the problem is with the SMC.
first i need voltage in to LE0301 .i dont know how can i do that?
Please help me.Thank you very much
