An Amiga that boots to a black or flickering screen has often been hit by leaking capacitors or a leaking clock battery. Surface-mount capacitors on the A600 and A1200 and the clock battery on the A500+ are common culprits, so many repairers inspect the board for residue before testing anything else.
Chris Edwards recaps an eBay A600 and finds a damaged wire under a socketed crystal. GadgetUK looks at corrosion on an A500+. When the machine will not run test software, RavenWolf Retro Tech uses DiagROM on a dead A500, which needs a serial cable and a second computer. Floppy faults are on the floppy drive page.
Battery residue and capacitor electrolyte are corrosive. An old NiCd cell is better out of the machine before it leaks, and a bulging or leaking one must not go back on charge. Recapping is soldering work, with burns and fumes, and the old solder holds lead.
