How to fix the light buttons that not always work properly?
I have a philips wake up light HF3470 and there are 3 buttons to control the light. (brigther, turn it on/off, dimm). Now 50% of the times these work properly. But sometimes when the on/off button is pressed, the light will dimm (as if the button below was pressed), and when the dimm button is pressed, the volume goes up (which is the button below it).
At first I suspected it to be a physical problem that the plastic of one button presses the other a little bit. But I dissassembled the light, and even when pressing the buttons without the white protectors, it still has the same behaviour.
