Have a coffee damaged 2936. Got green light, fan spin after replacing components. Still boots, then pauses and shuts down. Components near the edge, r4510, u5410, c5411 and the ISNS_HS_OTHER_N circuit, seemed to have most of the corrosion. Further, the resistors smc_kbc_mde, smc_tdo, smc_tck and smc_tdi were all replaced due to corrosion. All the resistors in the area check out, and no shirt to ground. Any idea? Anyone?

Also, one of the RAM cards was wrecked.

Try SMC bypass, does it power on???? Also check continuity between the parts you've changed, maybe broken trace...
