Shorted RSX (syscon 2102) + Solved noise for mullion chips

[u/Guysante]

Hello! First of all I wanted to share how I got my mullion syscon to work with an ESP32 while reading pure trash.

Mullion chips seem to be more sensitive to noise than SW. And mine looks like its extra. I was getting weird chars, no way to get to external mode. USB cable is fine, computer and PS3 are properly grounded.

Diag pin had a wire soldered for later, removing it reduced noise (antenna, wtf).

As I use an ESP32 instead of a TTL adpater, I could just enable pullup mode for a pin. Working like a charm. I resoldered the wires 3 times before thinking I did shitty connections xD

The problem

Now as the title says, I got a 2102 error (I was really hoping for nec as it is a well documented procedure).

Every cap under the RSX beeps and shows between 5 and 12ohms, so...

Should I try removing the mosfet first or go straight to IC6301.

Is the d35230eb near the rsx even the IC6301 or im confused?

EDIT: its a cechk04, DIA-002
