⚖️ Seller Warranty & Marketplace Dispute Conciliation
If the unit exhibits failures that cannot be resolved with basic self-troubleshooting steps, such as not powering on after checking the fuse, persistent distortion even at low volumes, or display issues not caused by misuse, there may be a manufacturing defect. In these cases, contact the seller or manufacturer to initiate a warranty claim under the seller's warranty and marketplace return policy.
