I knew since the day I got my GameGear that something was wrong with it. Whenever I used the AC adapter, the system got hot enough to make my hands sweat horribly. I somehow thought this was normal.
Then one day it made a popping sound and the image went out. I thought it was the whole screen, but I found out that if you shine a flashlight through the back you can see the picture.
How can I replace the backlight on this? It seems to be fine otherwise.
