Hi Bill, Do you mean the trimmer plate on the front? Or the blue rubber button on the side? The 5614 is easy to repair once we know the exact faults. Could you have a 5416? This had an on/off switch problem? I am a main service agent for Braun based in Hove and willing to help where I can, I always try and answer peoples questions on this site. Contact me for further info if needed. Thanks Jay
