My favorite game system when I was younger was this Sega Game Gear. I sat broken for many years. My mom recently was cleaning out the storage and gave me my old gaming systems. I wanted to repair my Game Gear and all those good memories.
The Sega Game Gear has a common problem with bad capacitors. I bought a Game Gear capacitor repair kit. The kit sorts all the capacitors you need and provides a good guide on how to replace them. I was a bit skeptical if I could successful complete the repair, but everything came out surprisingly well. It felt so good to switch on the game system that had been broken for so many years.
Don't accept broken as the final answer. Always try to repair.
