Today I have a Game Gear with a dim screen. This occurs because the capacitors on the motherboard need to be replaced. It happens due to the age of the console. As the electrolytic fluid inside of the caps breaks down or leaks out, they lose their ability to hold a charge.
No charge means that the screen is dim, or the volume is too low (or not there at all). It's all caused by the same problem, and for some reason, many consoles of this era have the same issue. Turbo Express handhelds, and even the Lynx in some cases, will exhibit this screen fault. Fortunately, it's a somewhat straightforward fix.
So how do you replace them? It involves opening the console with a phillips screwdriver and a security bit. Then you can simply desolder the old ones and put new ones on there. While it's a bit more difficult to source SMT caps that will work with the board, plain old radials will work fine. Let's get cracking.
Next time, I'll replace the plastic screen lens.
