The Ultimate Original Game Boy (DMG-01) Troubleshooting and Repair Guide


Nobody wants to spend the whole day troubleshooting. Do you have a problem with your hand held?
Nintendo doesn’t offer official support anymore, so we’re stepping up with our own official Gameboy troubleshooting guide! In this guide, we’re taking a look at some of the most common issues to arise from the Nintendo Game Boy.


How it happens
Shell damage is often caused by natural wear and tear. Game Boys were made to be mobile, so it’s common to find scrapes, scratches, dents, and much more on the outer shell.
How to fix it
The Game Boy shell can be removed to be cleaned with warm water and dish soap. If the damage is beyond something you can fix yourself, it might be necessary to replace the shell completely.

How it happens
Another common problem with mobile devices is the inevitable build up of grime. This can cause some serious issues with moving parts and is the leading cause of sticky buttons.
How to fix it
You’ll need to open the Game Boy and thoroughly clean the internal components. There are several pieces that need to be addressed, including buttons, contacts, and silicone pads. You can find more information on fixing sticky buttons on your Game Boy here.


How it happens
It doesn’t take much for something important to wiggle loose and completely out of sight. Some of the most common components to go missing on a Game Boy are link port covers, screws, and battery covers.
How to fix it
Official support for the Game Boy from Nintendo is no longer available. Parts must be replaced from used Game Boys or using third party reproductions. The Game Boy community is alive and well. It’s not hard to find several online retailers with custom parts, components, and shells.


How it happens
Game Boys were released with plastic bezels (the front plate covering the actual screen). This plastic is very sensitive to scuffs and scratches—especially after almost 30 years of gaming.
How to fix it
Scuffed screens can be easily replaced with aftermarket bezels. Vendors offer custom colors, designs, and even tougher materials like glass.


How it happens
Game Boy screens are already hard enough to see. Anything that makes it harder isn’t doing us any favors. But if you’re struggling to make out those pixels, it’s not the end of the world!
How to fix it
Make sure of the obvious stuff is out of the way and find yourself a good lamp. It’s impossible to make out a Game Boy display without an appropriate light source. But if lighting isn’t your issue, you may have to look a little deeper.
The Game Boy features a component not found on modern hardware. The contrast can be adjusted with a small wheel found on the side of the device. Use this to adjust the display until you find the perfect resolution.


How it happens
This issue is caused by micro-tears and general breakdown of the display cable wires. This ribbon cable is very delicate. As a result, it’s common to find vertical lines on the display as it breaks down.
How to fix it
The wires can be reheated using a soldering iron. This rebuilds the broken connections and allows display information to pass through again. You can find more information on how to fix Game Boy vertical screen lines here.


How it happens
The most common reason that your Game Boy won’t turn on is due to battery corrosion damage.
This is a common issue for Game Boys that have recently been dug out of storage. Many Game Boys end up in storage with a full pack of batteries. Battery corrosion can cause a multitude of problems if it reaches the internal components.
How to fix it
Battery acid damage does not mean the end of the world for your Game Boy. Most of the time, all you need is a little patience to get the hardware restored. Follow our guide here to learn how to clean the battery contacts on your Game Boy.


How it happens
If your Game Boy has no audio, the cause is likely due to one of these three components—the speaker, the speaker wires, or the headphone jack. Damage to any of these pieces can cause a complete lack in audio.
How to fix it
It can be tricky to identify the problem component, but each can be resolved by soldering a replacement into the Game Boy.


This is actually an issue with the game, not the Game Boy, but it’s easy to fix by replacing the battery in the game. Learn how to fix your Game Boy games that won’t save.


How it happens
Backlit Game Boys draw a lot of power. This draw can cause a serious strain on the components inside. If you find your backlit Game Boy extra whiny, it’s time to do something about it.
How to fix it
The Game Boy can be upgraded with a specific capacitor to let more power through, reducing whine from the speaker. I wrote an entire guide on how to fix Game Boy speaker whine!
