… or it wasn’t that extreme after all

Intro

Today I came up with another #short, slightly extreme. It wasn’t as extreme as previous examples, but it was still quite fun to fix.

If you are a long-time reader of my blog then you probably know about my previous posts covering extreme repairs.

I made a list of those posts for the fresh blog readers:

The Sony PlayStation 1

Błażej/Lamers^BooM asked me to have a look inside this console. I am not a PlayStation expert but apparently, this is one of the early releases – SCPH-1002
It was quite dirty and covered with rust so I assumed it was partially submerged in some sort of liquid for a decent amount of time.

After opening it, it was clear that the PSU and shielding were completely covered in rust.

I’ve managed to unscrew internal parts with the use of Black Magic lol

Most of the caps and some resistors were destroyed and required replacing.

The repair

I’ve removed all destroyed parts and cleaned the bloated solder mask on the other side of the PCB.

After that was done, I put the PSU PCB along with the logic board into ultrasonic cleaners.

I also had to address an issue with a non-conducting power switch. I’ve disassembled it and removed the oxide layer with a droplet of hydrochloric acid.

Meanwhile, I’ve prepared a phosphoric acid bath for the plastic case. This removed all the rust stains from it.

I’ve also cleaned and spray-painted all the shields with a zinc coating and assembly followed shortly.

It works!!! Yay! :>
