In this guide i will list all the capacitors that need replaced in your Sega Game Gear. Also I will highlight in red the capasitors that don't need replaced if you are replacing the screen with a new screen as they won't be used anymore.

Note the 3 main versions of game gear in the photo below

VA 1 = revisions 837-9130 / 837-9024 / 837- 8560

VA0 = revisions 837-7996 / 837-7719-01

VA4 and 5 are not compatible with new LCDs
