How to Backlight Your Game Boy Color

In this step-by-step guide, I will be showing you the best way to install a backlight into your Game Boy Color. There are a few different manufactures that produce these replacement screens and kits. However, most of them are not full-size screens, leaving an unsightly border within the lens of your Game Boy Color. Luckily, the one we shall be installing today is the Funnyplaying IPS kit. This is the best backlight for your Game Boy Color. The screen offers integer scaling, so each pixel looks sharp and it’s the same type of screen we installed in the GBA SP IPS mod here.

So, why should you use the Funnyplaying Screen to backlight your Game Boy Color? The backlight kit provided by Funnyplaying will backlight your Game Boy Color giving you a full-size screen unlike others, you won’t need to buy a specialist lens, do any soldering & as the screen is IPS you will get a fantastic viewing angle with no screen tearing

Here I have this old transparent Game Boy Color, it’s a little beat up but nothing we can’t fix. I’ve gone ahead and ordered a replacement teal shell to rehouse our backlit Game Boy Color. The screen is also a little scuffed so we will also be installing a replacement glass lens which will provide a higher level of scratch resistance.

Inside the GBC screen kit from FunnyPlaying, we have the IPS screen, Ribbon cable adapter and some foam doubled sized adhesive.

Game Boy Color Disassembly Steps

So, the first thing we need to do is take apart the Game Boy Color. This is pretty simple to do, first, make sure there is no game inserted and remove any batteries. Turn over your Game Boy Color and remove the battery cover, you then want to remove the 6 tri-wing screws on the back of the Game Boy Color with a tri-wing screwdriver. There are 4 screws on the outside and 2 screws inside the battery compartment. Put these screws aside somewhere safe.

With the screws removed the shell should separate, put the bottom half of the shell aside. You now need to remove the 3 x screws from the motherboard I will mark out below:

Now, these 3 screws are a little squarer than a standard phillips head screw, but you should be just fine using a normal phillips screwdriver. With the screws out of the way, we can get to the Game Boy Color’s motherboard. First, Remove the IR cover and volume slider and put them aside somewhere safe.

From here, pull up on the two tabs on each side of the ribbon cable connector at the top of the motherboard, this will allow you to remove the ribbon cable from the board. Lift out the Game Boy Color motherboard and put this aside. As this is an original Game Boy Color I want to take out the original screen, buttons and silicon membranes. The buttons and membranes just lift out of the Game Boy Color’s shell, however, the screen can prove to be a little more tricky. Gently and carefully twisting the plastic around the screen should help loosen it. It is held in with a strip of adhesive, if you are using your stock shell, you will want to take out this adhesive layer like below.


Now would be a good time to check if our screen is working properly before we begin to the install. The easiest way to do this is to connect your ribbon cable to the IPS screen. To make the connection, you push down the tiny connector on the screen into the ribbon cable. We can then connect the other end of the ribbon cable to the Game Boy Color’s motherboard. Gently place the motherboard into the back half of the case as shown below being careful not to break the ribbon cable and put some batteries in to see if your screen is functioning:


As you can see, our Game Boy Color backlight screen and ribbon cable work as they should. Disconnect your ribbon and screen and put them aside somewhere safe.

Now, this is optional, but it may be worth cleaning up the motherboard a little. After all, some of these consoles are 22 years old now! To clean the motherboard, use some high percentage IPA with a cotton swab or a toothbrush, you don’t need a lot of IPA and remember to be a little gentle with your scrubbing. If you are going to be reusing the original buttons and membranes and want to clean them, simply throw them into some hot soapy water and them to soak. This will have the added benefit of restoring some of the elasticity to the membranes which will make your buttons feel a lot better, just remember to dry them off fully before reusing them.

Next, we need to trim the inside of our shell. The trimming of the inside of the shell is necessary to fit the backlit screen into the Game Boy Color. If you are uncomfortable doing this yourself you can get a replacement shell pre-trimmed from Retromodding here (at checkout, use code ‘cheapergamer’ to get a small discount on your order).

Below I’ve marked out where we need to make our cuts. For this shell I am going to be using some flush cutters and a craft knife to finish everything off, alternatively, you could use a rotary tool like a Dremel if you have one. You can line up your screen and you’ll see exactly what areas need to be cut.


I find the best way to do this is to score the are to be cut with your craft knife then make two cuts either side with your flush cutters, this should allow you to fold back the excess plastic which should just snap off. My advice is to have a little patience and take your time after you finish you can ‘smooth’ out rough areas using your flush cutters or some fine sandpaper.

Now that your shell is cut, we can drop in our screen into our trimmed Game Boy Color shell and see if everything lines up.


Back to your motherboard, you will want to trim down the pins that stick out on the front side of the motherboard. These are the pins from the cartridge slot and can add extra pressure and damage the screens. To trim them down take your flush cutters and cut them down close to the board. There is also a tiny mound of solder we want to trim down using our flush cutters just below labelled ‘BT+’.
