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.
Questa è una buona domanda?

I'm also having this issue. None of the buttons work at all. Anyone found a solution internally?

Had same problem.
After going through each of the PCBs it tured out that one of the button fas not working and disturbed the function of the others.
I just removed VOL DOWN and everything started to work (except vol down). Replaced it with a cheap one from ebay and now it's just as new!
