820-00165 U3210 Burnt

[WiFiComputers]

Hi
I got a 820-00165 Motherboard for No Power
U3210 was burnt badly from top So I replaced it also C3285 and C3286 had Liquid Damage, Both replaced.
Still board is not powering up
Missing PP5V_S4rS3
PP3v3_S5 is 3.32V

Don't know where to start now

Check for any short on power rails of Thunderbolt area.

Trigger SMC_ONOFF_L and check for drop pulse at PM_PWRBTN_L at same time.

I did trigger R5115 by Shorting both points
I checked all Pins on C3210 nothing is low on resistance rest of the board in Mint condition, didn't find any short on power rails in thunderbold area

Can I bypass thunderbolt Area since originally it was burnt, definitely something is short in that area but I couldn't figure out
