Nintendo Game Boy Troubleshooting
The Game Boy is an 8-bit hand held video game device developed and manufactured by Nintendo. It is the original Game Boy, characterized by its large gray casing and reflective black and white LCD screen.
Note: This troubleshooting page covers only the original Game Boy. Every other Game Boy after it is covered in another troubleshooting page.
The System Does Not Turn On
Always make sure you have batteries that have a charge installed in the back of the Game Boy in the battery compartment.
No Batteries
You may need to check if batteries exist in the battery compartment. Also make sure that they are correctly inserted and that they are not "dead" batteries.
Faulty LED
The power LED on the left side of the screen does not turn on when the system does. This could be the cause of a broken LED and can be replaced.
Corrosion on Battery Contacts
Check if you have corrosion or other residue on the contact points in the battery compartments. This might prevent the batteries from transferring power to your unit. Use a screwdriver or similar to scrape the residue of the metal.
The Game Does Not Start Playing
Cartridge is not fully inserted
Make sure that when you insert your cartridge it is not blocked by dirt or other debris. Also check that the cartridge is going into the dock completely, allowing for a connection to occur. Also check for damage done to the cartridge itself, water damage and or shock problems can cause a technical failure with the cartridge.
Technical Problems With The Cartridge Reader Have Arisen
If your cartridge is fully functional and the system turns on but still the game does not load a technical problem may have arisen. The connections that run the game to the main CPU may have been broken or faulted.
There Are Bars Across The Screen
The Connections To The Screen Are Faulty
The connections to the screen are the most fragile connections inside the Game Boy, if these connections are crossed or manipulated in any way the screen will exhibit bars. These run length and width wise on the screen usually on the edges. Replacing the screen or Game Boy may be imminent if unable to repair connections.
Technical Reset Required To Clear Screen
Sometimes all the screen needs to do is have a technical reset to clear the connections and allow the screen to go back to working order. This can be done by accessing the screen via guide.
Buttons Do Not Work
Buttons Have Moved From Their Touch Sensitive Placement On The Main Board
If this is the case, you need to follow the repair guide and place the buttons back in their respective places, making sure that they line up with the repair guide instructions.
The Control Board Is Having Technical Problems
This would require an entire board replacement, which costs more than the actual Game Boy, buying a replacement is the only option.
There Is No Sound
Out Of The Main Speaker
There may be a connection problem, or the speaker needs to be replaced. Make sure that the speaker has had no water damage in the past.If the speaker is indeed broken, you can do a replacement, or you may need to do a complete replacement of the system.
Out Of The Headphone Jack
If the headphone jack is not functioning, there is most likely an issue with the connection and the entire piece needs to be replaced. This is an easy fix and follow the repair guide.
There Is Water Damage
If there was ever any water damage to your Game Boy system, there is a major issue. DO NOT TURN ON YOUR GAME BOY you need to let your system dry for a few days to ensure that the circuits will not short and cause the boards inside to fry to a crisp. Also after a few days make sure to go inside and clean the copper plating on the back of the CPU board, this copper plating can "Rust" and will cause shorts over connections. If a turning on of the Game Boy did occur the Game Boy need most likely to be replaced. Follow repair guide.

Hello,
Thanks for the advices, I have read it carefully.
My game boy switch on normally. and sometimes use to com a block instead of nintendo. But now It just doesn´t show nothing at all. It makes the initial clasic sound "cling" but nothing else.
I think it may be dirty the connections to the cartdrige but I have clean it and nothing changes. Maybe it is broken some connection inside?
thanks for helping

I bought a used Gameboy Advanced SP in Germany as well as a game which works well, but when I use the games that I had bought in Portugal the "Nintendo" sign does not appear when I turn on my Gameboy. I tried cleaning in the cartridge and the Gameboy but only the game that I bought in Germany works on the Gameboy that I also bought there.
What is happening?

Try opening the cartridge to see if any traces are damaged.

Last night my DMG was working normally (save for the one vertical line across the screen I didn’t get around to fix). Today I tried turning it on and the GB turns on but there is no sound and no image on the screen. The red LED shines brightly. The same happens if I turn the game boy on even without a cartridge inside. No image and no sound. I opened it up and all the capacitors seem OK and there is no visible corrosion. What could be wrong?

I have a GB that is in this exact state. Led shines brightly, although it takes a minute to come on. No sound, and no picture. Ever figure out what was wrong with yours?

Ips mod just solder new speakers not getting any sound and the screen crashes. After I pretest the screen before assembly is it a capacitor or did I do a bad job soldering
