I received a GameGear without sound and the contrast of the handheld was terrible.

So I used a searchmachine and found the following sites:

AudioFix

For Display troube

If you don’t want to make it yourself, we can take care of your gamegear

Part  #1 Audio Fix

In most cases it it this capacitor 47uF 6.3V (C7)
Please change 47uF 6.3V (C5) too, because if you make use of a headphone.

If you can’t find it with 6.3V you can make use of one with higher voltage.

C1 C2 C3 C5 C7	100μ 6.3V 100μ 6.3V 100μ 6.3V 47μ 4V 47μ 4V

Part# 2 Display Fix

The display was dark, the contrast wheel didn’t help, so I changed every elko on the mainboard.  After this the picture was brighter and the contrast wheel works good again.

The original capacitors have some clue under it.  Desolder one side of a capacitor and move it a litte bit. Then you can desolder the other site.

when soldering make space at the marked areas. It is needed when closing the gamegear.

Update: Bad Contrast Fix for other GameGear Revision

Here you can see all capacitors to be replaced.

Responseable for the bac contrast are: C54,C55,C48,C49 (blue marked Area). But its better to replace all to be sure.
