Why does none of the listed manufacturer codes work to control a component?
None of the listed manufacturer codes work to control a component.
You can try programming the remote control using the codes listed for the component type of other manufacturers. If the remote still does not control the component, you can try using the code listed in the manual for other component types. Also, some remote controls have a search feature that will allow you to test each code on the component. Refer to the instruction manual specific to the remote control for further information.
If none of the supplied codes work, the remote control will not be able to communicate with the component. In this case it will be necessary to use the remote control supplied with the component to operate the device or try purchasing a remote control with infrared (IR) learning capabilities.
