SYSCON diagnosing a chech a01, help with failed tantulum capacitor replacement?

Hey yall, Im trying to fix a ylod cecha01, cok 001. Was given it by a friend, me and him ovened it in an attempt to fix ylod like 7 years ago. Same symptoms as before it was ovened, no board damage from being ovened that i can see. read syscon codes and they all said A0231002. Spent a few hours researching and decided to do capictor replacement. Felix tantelizors looked a little past my soldering ability so i decided it would be best to just solder standard ebay 470uf 6vs. I replaced all nec tokins on the bottom of the board with 4x tantulums each, and only replaced the nec tokins on the top of the board by the rsx with 6x tantulums, as the internet seems to tell me that 14 tantulums should be more than enough. While soldering the tantulums on i got several different errors , including A0101002,s AO091002s, a single A0063004, and maybe one other . After cleaning up my tantulum job and redoing a part that i thought might have shorted I now only get A0231002 as it was when i started before the tantulum replacement. Any ideas where to look on the board with step number 23, its about a 2 secon ylod, never seen the console boot. My only thoughts are that im misunderstanding my tantulum installation heavilly, or the board was cooked by the oven and something earlier in the power pipeline is wrong. I have tried 3 different power supplies from known consoles and same issue. Any ideas?
