Nintendo GAME BOY Console (Defective)

This is a Nintendo GAME BOY.
Power has been confirmed.
However, operation has not been confirmed as there is no cartridge.
Also, when the power is turned on, the Nintendo logo descends from the top, and there are black lines in that area.
The contrast adjustment changes the display as shown in some of the images.
The volume adjustment changes the sound.
