In this episode of Chris Edwards Restoration, the spotlight is on another Dead Amiga 4000. The system arrives in poor condition, with corrosion, missing capacitors, and signs of instability. Chris sets out to see if this board can be restored. The process is long, but the outcome is worth watching.
The package includes more than just the faulty Dead Amiga 4000. Inside are a RAM expansion and a rare PCMCIA CD-ROM controller. These pieces are interesting, yet the real challenge lies in saving the 4000 itself. Early checks reveal trouble: black screens, a failed CPU test, and a machine refusing to boot.
Repairing an Amiga 4000 takes both patience and skill. Chris begins by testing the RAM sockets, reflowing the power connector, and replacing damaged capacitors. He explains each step clearly, noting how capacitor leaks often destroy delicate copper traces. In this case, the audio system suffers the most damage. To repair it, Chris rebuilds the area with new resistors, wire links, and precise soldering.
Progress comes slowly, but each test brings the board closer to life. Diagnostic ROMs confirm memory issues are solved. However, the audio remains silent. Chris traces the problem to a dead op amp, which he replaces carefully. On top of that, he uncovers broken traces, damaged resistor networks, and a bad CIA chip. Each discovery adds more work, but he handles them one by one.
After hours of focused effort, the project pays off. The Dead Amiga 4000 boots, shows a stable screen, and plays audio again. Testing proves the machine is now reliable. Even games run smoothly, a clear sign of success. Chris explains that years of neglect caused the failures, but careful work has given the board another chance.
This repair stands as another successful save for Chris Edwards Restoration. By taking viewers step by step, Chris shows how even a badly damaged Amiga can be revived. Fans of vintage hardware restoration will find this episode engaging and informative.
