PS3 Issues with syscon connection

Forum Noob
Hi all! I'm new to the forum, I'm trying to fix a PS3 for a friend that have a YLOD but I'm having issues

PS3 it's a CECHL04 i'm using a FT232 but I'm always getting "auth1 response invalid"

swapped TX and RX same error

tested with Putty if I set port to:

Baud 57600
Data bits → 8
Stop bits →1
Parity → None
Flow control → None

I get this message OK 00000000:3A

What could be wrong in Python ? what can I do now? I've checked also Python code and Buad Rate for SW it's set to 57600 so why it' failing auth? there is other way to download errlog ?

Is it connected to a GND reference, on the board? The syscon can be picky and really needs ti share same GND with the adapter. Also check continuity between a pad and the end of the wire
 
Yes, It's gnd connected.

ok, I managew to connect using Python script, probably GUI have sone issue.
I'm in here the log:

any suggestion? nec tokin replacement or it's RSX damaged?

The CECHLxx models have a 65nm RSX so the chances of a dead GPU are very low.

The 1002 errors are the NEC/TOKIN Proadlizers on the RSX side. You will need to replace them.
The 2124 errors are most likely a symptom of the dead NEC/TOKIN Proadlizers rather than something actually wrong and will probably stop getting generated after NEC/TOKIN Proadlizers replacement.

MattKC on YT had the same error codes in his 3 PS3s for 50$ video actually. I wouldn't follow it as a repair guide though.

Ok thanks! I will proceed by replacing the NEC/Tokin capacitor.
just one doubt, on the MB there are 8 NEC/Tokin installed, 4 on the Chip side and 4 on the back, I guess the capacitor are all connected in parallel, 4 close to the RSX and 4 close to the CELL chip. How do you understand which one needs to be replaced without disconnecting?
it's impossible to measure capacity or ESR till they are connected.
I will try by replacing the 2 on the RSX side and see what happen, but the 2 on the opposite side are connected with them in parallel right?

There isn't a way to easily test for individual failure as far as I know. I think the original advice is to replace one, try the console to see if it works, repeat until success.
Here are some pictures on how they are connected: (Research/Experimental) - NEC/TOKIN Capacitors Replacement - YLOD The more modern (and long term) solution nowadays is to use RIP-Felix PS3 Tantalizers instead of just tantalum caps because they connect V_IN and V_OUT (removing the need for you use wire if you remove all NEC/Tokins) and provide a smoother power filtering. He made a video on them too:
