K8095 starts automatically

Hello !

I have bought the K8095. It is a great product, it is exactly that what I was looking for.
The only problem I have at the moment is that it starts automatically.
It powers up and without pressing any key it starts playing. When I press the Stop
button or the sleep button it stops playing and then after some minutes it starts again
playing - without having pushed a button. Any idea ?

Thanks

It seems that for some reason the microcontroller IC3 detects that the play/pause button SW1 is pressed.
If you have a multimeter, you can check the voltage on pin 2 of IC3.
When no button is pressed, the voltage should be 0V.
When button SW1 is pressed the voltage should be 0.3V.

If there on pin 2 is some residual voltage when no button is pressed, this may cause the problem.
