Trying to fix my old Game Boy Color and the screen went completely black
I was in my garage in Phoenix last weekend, finally getting around to replacing the screen on my childhood Game Boy Color. I bought a new backlit LCD kit online for about 35 bucks. Everything was going smooth until I plugged the new screen's ribbon cable into the motherboard. I turned it on and got nothing, just a solid black screen with a faint hum from the speaker. My heart sank. I spent the next two hours checking my solder points with a magnifying glass, reflowing a couple that looked cold, and triple-checking the cable was seated right. I was ready to give up, but then I noticed the tiny contrast wheel on the side was turned all the way down. I gave it a tiny nudge with a small screwdriver and the picture popped right up, bright and clear. I felt so dumb but also relieved. Has anyone else had a simple fix like that completely stump them on an old console repair?
