Korg, like Yamaha and Roland, treats service manuals as intellectual property and liability shields. They do not want a hobbyist electrocuting themselves on the 15V DC supply or destroying the main CPU with static discharge.

Officially, Korg only distributes this manual to paid, certified repair centers. If you call Korg USA or Korg Italy and ask for a PDF, they will direct you to a local dealer. Furthermore, third-party aggregators like ManualsLib or ElektroTanya frequently have these manuals taken down due to DMCA copyright claims.

However, because the Pa700 was discontinued (succeeded by the Pa700 Genos competitor, the Pa900, and later the Pa1000/Pa4X), "leaked" copies exist in the wild, usually scanned at low resolution.

If you describe a specific problem with your Pa700 (e.g., “no sound from left speaker,” “touch screen not calibrating,” “faulty aftertouch”), I can provide:
