This is a Game Boy Color console. The reason for the issue is: It powers on, but there is no sound. Sound can be heard through headphones. The start button's response is not the best. This is an old product, so it may sometimes not work properly. However, I have confirmed that it works with a game cartridge inserted. The click feel of each button is good, and there is no degradation. The LCD screen is also in good condition for its age. Please understand the above before purchasing. Batteries and a game cartridge for operation check are not included. Please check the photos for scratches, etc., and purchase accordingly.
