Are you using the latest Stern GB code? Press the right menu button. Is the line still there?
I never seen a LCD display with a single line stuck on before.
Thanks for the help. It’s a single blue thin vertical line. The other stuff in the pic is just reflection. I figured it was the LCD display. The game is a month old out of box. Ribbon cable is new but I tried with a spare. Same thing. Unreal.
