Question
I have had my controller for about 10 years.  Last week it stopped working.  I punch all the buttons and nothing happens.  The read-out says "80" and there is the # 1112 in the upper right hand corner.  I tried changing the battery, but no change. Please help!

Answer
My experience with these controllers is that they have a fairly short lifespan.  You can try to reset it by removing the power supply and the battery for several minutes, then reconnect and reprogram.  If this doesn't help, you probably need a new controller.
