Service & Preventative Maintenance

• Capacitor Replaced: The SMD electrolytic capacitor in the upper right-hand corner of the board has been professionally replaced with a brand-new, high-quality component.
  

Why Capacitor Replacement Matters on SR-JV80 BoardsThe original surface-mount (SMD) electrolytic capacitors installed on 1990s Roland SR-JV80 series expansion boards are notorious for aging and leaking corrosive electrolyte over time. Left unaddressed, a leaking capacitor can eat away at adjacent circuit traces, cause audio dropouts, severe noise, or permanently render the expansion board unusable. Replacing this capacitor proactively protects the board from trace damage, stabilizes power delivery to the onboard ROM chips, and ensures reliable, noise-free operation for years to come.
