Remotes need replacement if they have been lost, chewed by the dog,
have a corroded battery compartment, or was not included in the tree you
just bought from the thrift store. Though they do sometimes
malfunction, if your tree is not responding, or showing odd colors and
sections, it is more likely the green receiver is malfunctioning and
your remote is fine. Again, ASK if you need advice and assistance
ordering the correct item, whether it's a remote or receiver.
