Korg USA Customer Service Versus Product Support
Customer Service
Korg USA Customer Service provides nontechnical assistance involving:
- Current promotions
- Authorized dealers
- Service-center locations

- Explaining normal product operation
Korg USA says Product Support cannot act as a general training service for personal sound design, composition, custom tones or other individual creative instruction.
Korg Authorized Service Centers
Korg USA directs hardware repairs to authorized Korg service centers. The service-center locator can identify nearby facilities that handle warranty and non-warranty repairs.
Before taking or shipping an instrument:
- Contact the service center.
- Confirm that it services the exact Korg product.
- Ask whether an appointment is required.
- Ask about diagnostic or estimate fees.
- Confirm warranty-document requirements.
- Ask who pays shipping or transportation.
- Ask whether accessories should be included.
- Back up all user-created data.
- Keep the repair order and tracking information.
Do not send an instrument directly to the Korg USA corporate office for repair. The current warranty instructs customers to use the seller or an authorized warranty service center.

The current warranty sheet and the documentation supplied with the exact product control. Product categories, promotional extensions and warranty terms can change.
How to Qualify for the Extended Korg Warranty
For an eligible keyboard, digital piano or rack module:
- Purchase it from an authorized Korg USA dealer.
- Register it online within 90 days after purchase.
- Save the registration-confirmation email.
- Keep the original itemized sales receipt.
Both the registration confirmation and original itemized receipt are required for extended-warranty service.
The following generally do not replace the original itemized receipt:
- Credit-card statement
- Bank statement
- Packing list
- Registration email by itself
- Photograph of the product without purchase documentation
Korg Warranty Eligibility
Korg USA’s warranty generally applies to the first consumer purchaser when the product was purchased from an authorized Korg USA dealer in:
- The continental United States
- Alaska
- Hawaii
- Puerto Rico
The product must be delivered prepaid to the original seller or an authorized Korg USA warranty service center with valid proof of purchase.
Common Korg Warranty Exclusions
The current Korg USA warranty generally excludes problems caused by:
- Misuse
- Improper maintenance
- Repair by an unauthorized person
- Shipping or transit damage
- Battery leakage
- Accident
- Fire
- Use outside the product’s intended purpose
- Loan or rental use
Damage to keys, screens, controls, connectors, cases or other parts from impact, liquids, improper voltage or unauthorized modification may not qualify as a manufacturing defect.
Imported, Used and Gray-Market Korg Products
Warranty coverage is administered by the Korg distributor in the country where the product was purchased.
A Korg product purchased from:
- An overseas dealer
- An unauthorized marketplace seller
- A seller outside Korg USA’s distribution territory
- A private individual
- A used-equipment store
may not qualify for Korg USA warranty coverage.
A customer who needs warranty service outside the country of purchase may have to arrange service through the original seller and pay international transportation costs.
Before Buying an Imported or Used Korg Product
- Verify the seller’s authorization.
- Confirm the voltage and power requirements.
- Confirm the language and regional software.
- Ask whether the warranty is valid in the United States.
- Check whether parts and service are available.
- Confirm that registration and software licenses can be transferred.
- Obtain the original receipt when possible.
Korg Product Registration Problems
Registration may require the model, serial number, purchase date and dealer. Certain products, including Kronos workstations, may require an additional public ID displayed by the instrument.
If registration fails:
- Confirm the model and serial number.
- Check for letters and numbers that look similar.
- Confirm the purchase date.
- Confirm the authorized dealer.
- Check whether the product has already been registered.
- Contact Korg USA Customer Service.
Registration does not transfer warranty coverage from an unauthorized seller and does not replace proof of purchase.
Korg Keyboard or Synthesizer Will Not Power On
A Korg instrument that will not power on may have a power-supply, outlet, switch, battery, cable, connector or internal hardware problem.
Basic Power Troubleshooting
- Use the power supply specified for the exact model.
- Inspect the cable and adapter for damage.
- Connect directly to a working electrical outlet.
- Remove unnecessary USB devices and accessories.
- Check the battery compartment when the model supports battery power.
- Confirm that batteries are new and installed correctly.
- Follow the startup instructions in the manual.
Do not use a power adapter merely because the connector fits. Incorrect voltage, amperage or polarity can damage the instrument.
Stop using a product that emits smoke, sparks, unusual heat, electrical noise or a burning odor.
Korg Keys Do Not Play Correctly
Key problems can involve:
- No sound from one or more keys
- Uneven velocity
- Sticking or physically damaged keys
- Aftertouch problems
- Incorrect transpose or split settings
- MIDI filtering
- Local Control settings
- Damaged key contacts
- Liquid or debris intrusion
Test another sound or program and review transpose, split, MIDI and Local Control settings. A physical keybed or contact problem generally requires an authorized service center.
Do not spray cleaner into the keybed or disassemble the instrument.
Korg Has No Sound
Check:
- Master volume
- Headphone connection
- Audio-output routing
- Connected amplifier or mixer
- Local Control
- MIDI settings
- Mute and solo status
- Program or combination levels
- Damper or expression-pedal assignment
- Audio-interface settings
Test headphones and another output when safe. If the instrument’s internal speakers, headphone output and line outputs all fail, contact Product Support or an authorized repair center.
Korg Display Is Blank, Frozen or Unresponsive
A display problem can involve:
- Power-supply failure
- Startup software problem
- Failed display or backlight
- Touchscreen calibration
- Corrupted data
- Interrupted firmware update
- Internal hardware failure
Do not repeatedly interrupt power while the instrument is updating or writing data. Record the startup screen, error message and firmware version before contacting support.
Back Up Korg Workstation and Arranger Data
Before repair, firmware installation, factory reset or operating-system update, back up important user data when the instrument permits it.
Data may include:
- Programs and combinations
- Set lists
- Sequences
- Samples
- Styles
- SongBook entries
- Global settings
- User scales
- Custom sounds
- Performance and registration memories
Tell the service center that the instrument contains user-created data, but do not assume that data can be preserved during repair.
Korg USB-MIDI Driver Problems
USB-MIDI problems can involve:
- Unsupported operating system
- Outdated Korg driver
- Incorrect USB cable
- USB hub compatibility
- MIDI-port configuration
- Driver conflicts
- Digital-audio workstation settings
- Device permissions
- Operating-system security changes
Before Installing a Korg Driver
- Confirm the exact Korg product.
- Confirm the Windows or macOS version.
- Read the compatibility chart.
- Remove an older driver when the instructions require it.
- Download only from Korg’s official site.
- Disconnect or connect the product only when instructed.
- Restart the computer when required.
Do not install an unofficial driver package or a driver intended for another product merely because it has a similar name.
Korg Firmware and System Updates
Firmware and operating-system files are model-specific.
Before updating:
- Confirm the complete product name.
- Confirm the existing version.
- Read the complete update instructions.
- Back up user data.
- Use reliable electrical power.
- Use the required USB drive, cable or computer utility.

- Unsupported operating system
- Purchase through a different app store
- Network or security-software interference
Do not publish a license key, activation code, Korg ID email, receipt or screenshot of the complete software account.

- Exchange eligibility
- Damaged delivery
- Missing accessory
- Wrong item
- Refund method
