Found it.
I have a few questions though. I have a syscon A0801002 on my CECHC that according to db260179's ps3syscon project on Github is
"A0801002 = RSX Power on VRAM failure (Potential NEC tokins issue and VCC)"
I take I should just try starting to replace the NEC/Tokins caps near the RSX...
Sorry if this was asked before and is lost in the middle of the thread. Can someone tell me what case codes (either in or mm) or sizes of caps I should look for for tantalum caps replacements?
