"Do you want this old thing?" My uncle asked, pulling the old Game Boy from an end table drawer. "Your cousin didn't want it anymore so I've kept it. Your aunt and I played Tetris on it for years, but now the screen's all messed up and the buttons hardly work."
Memories flooded back to me of begging my cousin for a turn at Metroid 2 in the back seat of my aunt's Chevrolet Corsica on the way home from the zoo. Passing it around playing Kirby and Super Mario while at a birthday sleepover with a dozen other 3rd graders. Pleading with my Dad for one for my own birthday.
As I flipped the switch, Tetris music filled my ears. It was dirty, and the screen had vertical lines, but I couldn't say no. It was FINALLY mine!
I got to work right away. I was able to resolve the vertical lines by reflowing the solder on the screen, and then I cleaned up the motherboard with alcohol while I soaked the shell in an Oxyclean solution. Now she's running in tip-top shape! A friend called me a glutton for punishment for not replacing the screen, but I want it just like it is. Every scratch tells a story!
Super excited! Had to share with y'all!
Hey! So I had to clean the contacts on the motherboard fairly vigorously with rubbing alcohol and a microfiber cloth in order to get the buttons to register again. In my case it appears that something sugary had been spilled on the Gameboy and seeped down to the motherboard. I didn't have to replace the buttons, just clean the button membranes of residue.
And the Oxyclean solution I used on the housing was about 1/4 cup liquid concentrated Oxyclean to 32 oz of warm water. I soaked all plastics for 2 hours and then I brushed with a soft bristle toothbrush. It won't damage the color of your plastics at all, but may lighten them to the degree that you can see in my pics. Lots of people use the Oxyclean solution for colored Gameboys. There are suggestions out there for stronger solution recipes but I didn't want to take any risks. More than anything, it seems like Oxyclean helps with the yellowing that occurs over time, but beyond that, the soak helps make the grime loosen up so it can be brushed out of the crevasses.
Edit: you will need a precision screwdriver set that includes triwing bits to disassemble the Gameboy. I got a budget set on Amazon by a company called "Jorest" for $9 USD. It included all the right bits and spudgers and picks to get it cleaned up no problem. I'm not sure if links to products are allowed here so I'm not comfortable providing a direct link. Part number was AJJOJM0101ORDCAR1 if that helps.
Thanks for all of the advice! I'll have to try and get my gbc working again too. I knew I needed some specialty bits to disassemble but wasn't completely sure what.
You can do it! Dive in, and provide us with an update when you get it up and running!
I've got the tools, I just need to get some oxyclean so that I can avoid disassembling the device multiple times, lol. I'm kinda busy and I'm hoping to get to it next week during my weekend.
