Liquid damaged board, replaced U7200 and surrounding components. All measurements as they should be. Checked unwire circuit and PP3V42, SMC_BC_AOK are present. Power draw on PSU 0.019 - 0.025.
PPBUS_G3H = 12.6V
PPBUS_S5_HS_COMPUTING_ISNS = 12.6V
PPBUS_S5_HS_OTHER_ISNS = 12.6V
PPDCIN_G3H = 16.09 - 16.13 fluctuating (0L to ground at C7031)
PP3V42_G3H = 3.4V
PPVRTC_G3H = 3.39 - 3.44V fluctuating
PP5V_S5 = 3.80 - 4.65, occasionally 5V, fluctuating constantly.
200K-ohm to ground on PP5V_S5. Before I start injecting I feel like I'm missing something... Any feedback appreciated
