SEGA Master System - It's DEAD - But can I fix it? Quick Fix it Friday
335In this episode of Fix It Friday, I take on a Sega Master System 1 that I picked up as “faulty, no power” for around £20. We’ll open it up, investigate the possible causes, carry out the repair, and then put it to the test with a game.
Along the way, I’ll share my approach to console diagnostics, testing with a multimeter, safe soldering tips, and reassembly techniques. The aim is to make this the kind of repair you can try at home with basic tools and inexpensive parts.
Topics covered in this video:
• Testing a Sega Master System for power faults
• Possible reasons for a console not powering on
• How to methodically diagnose an issue
• Safe soldering practices for retro electronics
• Testing a repaired console with an Everdrive
