Hello masters I got a board with a short to ground on 3.4v I inject 3.4v and find out u7000 was getting hot , I replace it and short gone , I got back green light and after a few fixes PPBUS_G3H works also , after several diferent replacement of parts I got the machine to power on fan spins I test the board and I find out no chime or display then I when to check resistors R7403 and and R7402 and I have good voltage on pin 2 of booth =PPVIN_S0_CPUIMVP is ok but on the other side of resistors I have .5v on each they match ohms on schematic , and I desolder one side to separate the resistors from pin 1 of the board , and now I find out voltage go just fine on each side of resistors when they have no link to U7400.
What should be my next step?
