Migliaccio & Rathod LLP is investigating reports that certain Denon AV receivers may suffer from premature HDMI board or digital board failures that prevent the receivers from properly transmitting video and audio. Consumers report losing multiple HDMI inputs simultaneously, experiencing persistent black screens, or losing ARC/eARC functionality despite replacing cables, updating firmware, and testing multiple televisions and source devices. Many owners allege that the only available repair is replacement of the HDMI board at significant expense, often shortly after the warranty expires.
Consumers report:
- Multiple HDMI inputs suddenly stop working.
- The receiver displays a black screen or “No Signal” despite connected devices functioning properly.
- ARC or eARC audio unexpectedly stops working.
- Video intermittently drops out or disappears entirely.
- Problems persist after firmware updates and factory resets.
- Different HDMI cables and source devices produce the same issue.
- Devices work normally when connected directly to the television.
- Authorized repair centers diagnose a failed HDMI or digital board.
- Repair estimates costing hundreds of dollars.
- Replacement boards or replacement receivers later developing similar problems.
- Warranty coverage being denied because the receiver is no longer covered.
Potential claims may include:
- Violations of state consumer protection statutes.
- Breach of express warranty.
- Breach of the implied warranty of merchantability.
- Fraudulent concealment or omission.
- Magnuson-Moss Warranty Act violations.
- Unjust enrichment.
- Declaratory and injunctive relief.
