My sons gameboy advance sp screen wont show the game you can hear the game playing but cant see it on the screen?”
“How to Troubleshoot the Screen on a Game Boy Advance SP” STEP 1: Turn off the power on the Game Boy Advance SP and make sure the Game Pak is firmly in place with the label facing away. STEP 2: Examine the screen. If the unit’s screen is broken, you should see discoloration. STEP 3: Make sure the power switch can slide into the “On” position. STEP 4: Check the screen again. Make sure the protective plastic film has been removed. If you see bubbles or discolored lines on the screen, the film may be the cause. STEP 5: Adjust the contrast knob on the side of the unit. From here, you can check the screen’s brightness. STEP 6: Use a different game to determine whether the problem is with the Game Pak or with the unit itself. STEP 7: Ensure that the battery is fully charged.
