Need some help diagnosing PS3 super slim PQX-001 CECH-4206C

[Andrew222]

So I got a PS3 Super Slim a while back, and found that it doesn't power on. I decided I wanted to try debugging it using the syscon to see what the issue might be.
Problem 1:
[Power light won't stay on]
The power light isn't typically on when plugged in. It doesn't seem to respond to me plugging in the system.
Occasionally, at random, I will get a beep, see a green flash on the power light, and see the fan spin a bit before the light dies. There seems to be no rhyme or reason to when this happens.
Earlier, not sure if I did anything to trigger it (don't think so. I think it just happened), I managed to get a blinking red light.
I'll just get a random beep while I wait on standby next to the PS3. Not sure what I need to do to get the standby light to just remain on.
I'm wondering if this might be a power supply issue.

Problem 2:
[Keep getting Auth1 response invalid error message]
So the syscon on this board is the SW3-304. Don't think it's relevant, but I think worth pointing out.
So I made absolutely sure that I soldered the Tx of the mobo to the Rx pin and vice versa on my Raspberry Pi Pico. Also checked continuity to make sure I didn't bridge anything. I'm using the debugprobe on Pico firmware provided by Raspberry Pi which lets me use my Pico as a UART USB adapter.
Every time I try to AUTH or auth, I get the Auth1 response invalid error.
I'm guessing I need to do the authentication while the standby light is still on but I haven't been able to get that to happen.
If there's something else I could do to see why I'm getting this error or to work around this, I'd appreciate the input greatly.


# UPDATE 1
Just decided to try again, with nothing different, and managed to get an Auth successful message ONCE until it went back to Auth1 response invalid
Attached a screenshot of it here

# UPDATE 2
Managed to get a syscon output!! However, I get an error code that doesn't seem to be known A0012040
The other errors I get are rather unhelpful

A0A02130
A0502130
A0A02131
A0802131
A0003001

According to psdevwiki, A0A02130 means that this is immediately after syscon reset, and corresponds to Thermal Sensor Error (IC1101)
3001 corresponds to POWER FAIL

So... not so helpful

here's the full log output
