Game Boy Game Boots Up And Goes Black Game Boy Cartridge

Chosen Solution

I recently bought a Game Boy game on EBay. I put it in my Game Boy and turn it on. It turns on like normal, then goes black. Anyone know anything about how to fix it?

Try cleaning the contacts with windex and drying with a cotton swab or paper towel. The game may be damaged internally.

Try to resolder all the pins, mine had a broken solder near a capacitor, only visible trough a microscope
