Good day! After it turned out that the tablet does not turn on from the battery without a connected USB cable, diagnostics began according to the block diagram. As soon as we got there and found out that according to the block diagram, there is 1.8 Volts on capacitors C427 and C428, and 1.2 Volts on C430, it was decided to replace the power controller. Why it is unclear to replace the power controller? After all, it was not checked whether the power controller raises the main voltages or not. What led to paying attention to this transistor, which should pull a certain line to ground?
