Hi,
I have an NVA-001 Ps4 Pro with long blue light of death, visual inspection looks fine apart from dust and the very dried thermal paste which I cleaned and replaced, I scoped the board around for any shorts on capacitors and there were none, no blown fuses either. Looking under a thermal camera, southbridge gets warm along with APU and phases for the APU. I cannot tell if RAM is too cold? maybe not powered? but RAM chips are all the same temperatures. At this point I removed NOR and enabled UART to diagnose further. The only thing I get from UART is this following message:
at which point it hangs indefinately.
the only details I found about this was on a russian youtube video and some forums stating that most likely a possible fix would be to reball the RAM chips. I'd like to verify that this is indeed the issue and that the RAM is receiving power as to me it looks like it's slightly too cold. Please see the attached thermal images below.
I'm basing my comparison agains The Cod3r's video on diagnosing a ps4 pro with long BLOD, although it seems the fault occured for different reasons the ram chips in his video seem to be getting quite hot compared to mine. see his video here

Had I somehow corrupted or incorrectly resoldered the NOR IC the Serial data wouldn't be visible correct? Just want to confirm that I did not create this issue.
Appreciate your time and help.
Thank you!
