Recently, I came across a Gameboy at Goodwill for $6.99. While inspecting it I noticed the battery contacts where very corroded but the Gameboy was complete albeit very dirty likely from years of use and the lack of the previous owner taking good care of it. I couldn’t test the Gameboy before I bought it but I thought I could use a low budget trick to clean up the battery contacts to look nearly new.

When I got home I tried to turn on the Gameboy with new, fresh batteries but it wouldn’t power on. I wasn’t very surprised though because the battery contacts where nasty. Here’s some before pictures.

What you need:

  • Small flat blade screw driver
  • Needle nose pliers
  • White distilled vinegar

How to remove the battery contacts

I used a small flat blade screw driver to get underneath the battery contacts and then used needle nose pliers to pull out the battery contacts.

White Distilled Vinegar does a great job of eating through the corrosion on the battery contacts. All you need to do is soak the battery contacts in the vinegar for a few minutes. You can see the corrosion bubble right off. You can also use a flat blade screw driver to scrape off any corrosion that doesn’t bubble off on it’s own while it’s soaking.

After 5 minutes of soaking I removed the battery contacts and cleaned them up with water. Next I soaked them in some Rubbing Alcohol and then dried them using a paper towel before reinstalling them into the Gameboy.

Here’s a close up of the battery contacts installed:

Does it work now?

I reinstalled the batteries and tried to power on the Gameboy and to my delight it turned right on! This is proof of a cheap DIY fix for a non working Gameboy. There was a catch though…

I did notice that once the Gameboy turned on that some of the lines on the lcd were not being displayed. Luckily there’s a DIY fix for this too.

A common problem with Gameboy LCD screens is missing lines in the screen. This is usually caused by a bad connection in the LCD cable. When you heat up the cable and apply pressure on it the lines will disappear.

All you need is a hair drier or a heat gun. You want to heat the cable where it’s missing lines. Take a look at the picture I added for a better description:

After heating up the cable and applying pressure it looked perfect! Hopefully this information helps somebody with similar problems with their Gameboy.
