Yesterday, I got a Gameboy SP at a church sale for $8. I just got around to testing it out today and I found out that it doesn't work! When I plug in the adapter to charge it, the charging light comes on but when I switch the gameboy on nothing happens. I left it charging for about an hour and when I came back the light was no longer on, I then tried to power it up but again, nothing happened. The gameboy is in good shape with no damage or anything that would lead me to guess the problem. At first I though it might be the battery, but it would've powered on while it was charging. Does anybody have a good guess of what might be wrong with it?
