has any one had problems with pairing a controller to the main board. These items were both new from the factory and worked on and off during the installation of the main board used to check different sounds as being installed but stopped working 5 am fuse on main board is good and the 2 AAAA batteries in the controller are also good, another older controller tried also and works fine. Have try twice to reach Del at factory but as of yet no reply, and help would be appreciated, Bill
