KORG N364 Problem

Описание: In this video I show how to fix the “Low Battery” warning on a Korg N364 workstation by replacing the internal backup battery and restoring the lost data (if possible). I go step by step, from opening up the keyboard to soldering and testing.
This is especially helpful if your N364 keeps losing patches, shows a blank display, or gives error messages after powering on.

The official N364 manual mentions: “If the display shows ‘Battery Low’, the battery should be replaced.”

In forums, users report that after the low battery state, memory contents can be lost unless backups were made

Some earlier users note that the battery in N364 is often soldered directly to the board, so desoldering skill is required
