Following on from previous repair. This board had a new U7100, Q7130, DC In Board and DC Flex Cable to bring back green/orange light. It still wont turn on and I have the following:
PPBUS_G3H = 8.5v
PPBUS_S5_HS_COMPUTING_ISNS = 8.5v
PPBUS_S5_HS_OTHER_ISNS = 8.5v
PPDCIN_G3H_ISOL = 14.9v
PPDCIN_G3H = 14.9v
PP3V42_G3H = 3.42v
PPVRTC_G3H = 3.32v
PP5V_S5 = 5v
PP3V3_S5 = 3.32v
PP3V3_S4 = 3.32v
PP5V_S4RS3 = Dead / Pulsing
PP5V_S4RS3_EN = Dead / Pulsing
PP5V_S0 = Dead / Pulsing
PPVCC_S0_CPU = Dead / Pulsing
(The pulsing is so quick that the multi meter has trouble recording the values.)
No fan spin at all.
Nothing looks corroded here but I have checked all resistors, traces and continuity around Y1905, U6100 and U1900 and everything checks out.
Any help much appreciated.
