Game Boy: conflicto con los botones en gameboy

Mon, 03 Jun 2024 08:30:36 -0700

Hola, buenas tardes, vengo a exponer un problema que sufro en mi gameboy y no se a que se debe. La gameboy funciona bien pero hay un conflicto entre los botones y el conflicto es el siguiente: Cuando presiono la cruceta todo va bien y sin ningun problema. el problema empieza cuando presiono los demás botones. Al presionar el boton a se activa el cursor a la derecha, lo mismo pasa con b pero el cursor a la izquierda. Y con select y start pasa lo mismo pero arriba y abajo respectivamente. He estado buscando soluciones por todos lados y no he encontrado nada que me sea de utilidad. Tengo que resaltar que esto es problema de la placa principal y no de la placa con la pantalla. Ya que conectas la placa con pantalla a otra placa principal y fuinciona perfectamente.

Game Boy: ¿Por que mi contraste no se estabiliza?

Tue, 14 May 2024 14:48:36 -0700

Buenas;

Me compre una Game Boy de segunda mano a la cual le arregle las barras de pixeles muertos, pero el problema que tengo con ella ahora es que el contraste cuando lo subo o bajo, este cambia drásticamente o no llega a funcionar directamente.

¿Alguien sabe cual es la solucion a este problema?, y si es de la rueda ¿Como la reemplazo?

Game Boy: When I turn it on, the Nintendo logo is a black bar, can this be fixed

Mon, 10 Aug 2026 19:56:36 -0700

So I don't have any games for it, but I've been wanting to sell this game boy and I was wondering if there were a way to fix it. When I put batteries in it, and turn it on a black bar falls from the top of the screen (I'm assuming it says gameboy, or Nintendo.) Also the battery light is red. I'm not sure if that's good or not, but I'm just wondering if you could help me. Thank you for your time!!

Game Boy: red light, sound but White/Black screen | led ok, son mais pas d'image

Fri, 17 Apr 2026 10:47:55 -0700

Hello,

I tried to fix my GB DMG but I could not. The problem is pretty simple, I have red light, sound, game starting (I can hear the music of the games) but nothing on the screen.
I know it's not coming from the screen board because I tried with two other screen board from two working gameboys and I have nothing on the screen when I try on this particular one.

My guess is that something is wrong on the other board (the one olding CPU, cardridge reader, power) but I could not find what.

I cleaned up everything with IPA and contact cleaner with no success.

I am running out of ideas so I'm posting here in case someone can help me.

Bonjour,

J'ai essayé de réparer ma Game Boy DMG, mais sans succès. Le problème est assez simple : le voyant rouge est allumé, le son fonctionne, le jeu se lance (j'entends la musique), mais rien ne s'affiche à l'écran.

Je sais que le problème ne vient pas de la carte écran, car j'ai essayé avec deux autres cartes écran provenant de deux Game Boy fonctionnelles et le même problème se produit.

Je suppose qu'il y a un problème sur l'autre carte (celle qui gère le processeur, le lecteur de cartouches et l'alimentation), mais je n'arrive pas à trouver laquelle.

J'ai tout nettoyé avec de l'alcool isopropylique et un nettoyant pour contacts, sans résultat.

Je suis à court d'idées, alors je poste ici au cas où quelqu'un pourrait m'aider.

Game Boy: Light spot stuck on the screen after backlight mod

Fri, 16 Jan 2026 01:14:20 -0700

After doing the bivert and backlight mod on my dmg It looked fine for a while, but recently this light spot appeared. I tried disassembling and cleaning the screen, but it seems to be within the actual screen. My thought is it might be dead pixels, but the shape itself looks very much like something trapped under the screen. What do you think it could be?

Game Boy: Does anyone know where I can find an LCD for this?

Wed, 24 Dec 2025 16:16:54 -0700

Hello! I took apart my original model Game Boy because the screen was showing vertical lines on the edges, and I've heard that it's usually a problem with the LCD ribbon wire. I tried gluing it down again, which didn't work, so now I think I'm better off getting a new LCD with a pre-attached ribbon wire. I've searched around the internet a little, but all of the LCDs for sale require you to attach the ribbon wire yourself, which I haven't had much success with, as aforementioned. Does anyone know if I can get one with the ribbon wire attached?

Game Boy: Screen not displaying correctly

Sat, 08 Nov 2025 18:33:07 -0700

When I turn my gameboy on the screen has a big black box on it. If I put a game in it makes the Nintendo ding but nothing happens. I’ve attached pictures of the screen. I’m assuming it’s a gameboy issue and not a game issue or is it a both issue? Is it fixable !?

Game Boy: DMG-01 works only when motherboard is hot

Sun, 03 Aug 2025 14:34:30 -0700

I have a strange issue with my Gameboy Classic (DMG-01) that I am trying to fix. Bootup sequence is good, with logo and sound but everyting dissapear after a second and no game is loaded.

I cleaned everything, replaced cartridge socket, resoldered CPU and memory but no luck so far. What is interesting that everything works perfectly IF motherboard is heated with a hotair.

Also what is worth to mention Tetris works fine regardless temperature but no luck with Super Mario Land 1 and 2 at 'normal' working temps.

Could you please advise or tell me what else to check? Thanks a lot!

Game Boy: Only the “Up” button of the directional pad does not work

Fri, 27 Jun 2025 01:37:22 -0700

Hello everyone,

After installing an IPS screen in my Gameboy Classic, the top button of the directional pad no longer works. All other buttons work perfectly fine. Since switching to an IPS screen also changes the circuit board with the button contacts, these are new. Cleaning the contacts, as is always suggested for such button problems, does not help here. I now suspect the fault could be somewhere on the old circuit board, as I have already successfully measured the signal from the button to the ribbon cable with a multimeter. So the button contact is obviously transmitting signals, but they are being lost somewhere on the old main board.

Hello! I have a Game Boy DMG01 that has moving vertical black lines on the display while playing games. I have tried recapping the display board and main board with no change. I also tried a soldering iron to heat the ribbon connector which fixes non-moving black lines for most people, but this did nothing for me. Has anyone else ran into this issue?

Game Boy: Faint "scan" lines moving across screen

Tue, 30 Jul 2024 10:17:58 -0700

I have a fully original gameboy that up to this point has operated perfectly and has never been abused. Today I noticed what looks like faint darker contrast lines moving slowly upward across the screen. Like the effect you see when shooting video of an old crt screen with a video camera (but not so extreme). Here's a link showing it. I am adjusting the contrast to show how it becomes more noticeable the darker the contrast goes.
