820-2915 short on 3.3V rails.

Hi. I have this board that was liquid damaged. U7201 was damage and replaced. ISL area was damage and replaced. Q7260 was welded to the board. All my 3.3V S5, S3 and S0 rails are beeping to ground. I am asking for the best way to troubleshoot this issue before i try on my own and fuck this thing up more. Sometimes I tend to that. LOL.
Thanks in advance.

Yeah this board is trash, PPBUS got to 3V rails, the end.
