Diode mode on sda line was different than scleras, ultrasonic again was able to get me 8.4 on PPBUS, now an all_sys_pwrgd issue i think all_sys_pwrgd measures 0v. Q7950 has all 4 voltages present, and the 6 parent lines of the pgood signals supplied by 3v3_s0 are present, how would i go about checking if these lines are making the pgood signals for example if i have 1v8_s0 how would i know if 1v8_s0_pgood is present since all the pgood signals measure 0v,
so replaced u7100 and connected c7103 and r7147 since the test point was corroded, board does boot now but takes 300ma (20watts) that seems a bit high, it should be fine as long as it boots?
