Known Issues
Three electrolytic capacitors are leaking, try to replace
Causes
- Produced in 1987, electrolytic capacitors are prone to leakage
Solutions
- Recapping
Disassembly Notes
The leaked electrolyte corrodes and causes solder oxidation, which makes it difficult to desolder. Be careful to avoid high temperature damage to the pad
