    Good afternoon, this mac was not working HDMI, I performed U2800 and it worked again. Now the customer returns with the defect of not reading data from SSD/HD 2.0/3.0. I performed the replacement of the two cd3215 but did not solve it.

    820-00928 No Power

    Suddenly the mac turned on using another charger. I left it in tests and out of nowhere it turned off and won't turn on anymore. It is intermittent, out of nowhere it turns on. I would like to know if the components I already replaced are U4200, U3906, U4401, U5850 and U3100 ? PPBUS 12,6V
