Now just scapped my second set of these scales. Both failed after 12-24 months. Thanks for the teardown. I managed to get in, but no loose wires or clear problem area to fix. I took photos along the way. See google docs. https://goo.gl/photos/gmzFWdz769qiL42f6 The center disc came off very easily, but the 4 corner adhesive pads too quite a bit of leverage. Also I had to cut the wire to the centre disc to remove the glass plate. The plan was to solder this back together if I got it working. The display ribbon cable came out by releasing the catch, but the circuit board was glued to the back plate. Unless it is a loose wire, you would need to be an electronic engineer to fix it.
