Hi! 
Following a big sound problem
then comes the worst. the Neo Geo - Pro Bo dead chip cracked
So Pixel Porridge on the screen
I decided to startDesoldering at the hot air station 



Installation of the new Neo Geo - Pro Bo chip

Changing the Zilog Z80 to a faster Z80A
It was supposed to be installed at the base but not for a question of budget SNK
did not install it.in addition it is marked in white on the PCB

Installation support IC
Here it is black

Full Capkit Nichicon Audio & Standard and change of Mono / Stereo Switch

PCB Fryer Cleaning: lol: (Ultrasonic Cleaner)
Wow it shines!

Even the resistor shine


PCB port cartridge Ultrasound also and capacitor change

New rechargeable button cell ML2032 & battery holder

Wooden board to install the PCB with central foot to straighten the PCB flat

And there you have everything is beautiful, clean, brand new and functional



The components that I have avoided leaving on the PCB for the Bath are the Dipswitches to prevent the water from entering.the battery holder & Mono / Stereo Switch all 2 are new so no need
