For your Furrion FEHD19AOA TV/DVD combo, compatible replacement remotes include the Furrion DV7100 and DV7200 entertainment system remotes. These remotes are designed to work with Furrion combo units similar to yours. The "kontso a51" marking inside your battery cover likely refers to the original remote model, but matching by your TV model is more reliable. We recommend reviewing the remote specifications and button layouts to ensure compatibility with your specific unit. If you provide photos or additional model numbers from your TV, we can assist further in identifying the best remote. Our store offers returns for remote controls if they do with your system, so you can purchase with confidence. Please let us know if you'd like to proceed with one of these remotes or need more help identifying the right one.
