Philips HF3520/01 Wake-Up Light - suddenly starts making never-ending quick “clicking“ sounds, speeding up.. This is normally sound of proximity (touch) sensor.. but there is nothing close to device, and it is clean…. It is unstoppable, only it stops if disconnected from power… After connecting it can work for hours correctly, but problem appears later again…
