So my Game boy had the problem where some of the lines in the screen wouldn’t show up, so I tried fixing it. After a while though the screen stopped turning on and I can’t find out the problem. When the switch isn’t all the way on it shows some lines lit up so I know the screen works somewhat. Also, the noise plays when I turn it on so I know that it is working. I tested the contrast wheel and it appears to be working. Please help me with my problem.

Sean 29 start off by replacing the screen to rule it out (or in) as the cause of this. Game Boy Screen Replacement
