The simplest way to check that a remote is transmitting is to shine it at the lens of a camcorder or digital camera.When you press a button on the remote you should see a light at the front of the remote.If there doesn't seem to be any sign of life,check that the infra- red led on the main board of the remote hasn't come unsolderded from the main board,also check the battery connrections are soldered ok onto the board.Sometimes there's a crystal or resonator that can become loose on the main board..best of luck....Gordon
