Problem with shift botton and other issues

edited September 2014 in General
Hello everybody!
We have just build our lxr machine, and at the first look everything seems work fine.
But, in fact there are some issues.
The first is that when i press the Shift botton, it remains hold and the only way to turn off the button is to power off the machine. Or it starts to blink (and also all the led start blinking) for 10 second and it turns off automatically.  Is that normal?
The secod issues it's about the copy/clean led button. When i approach with my hand without touching start to blink everything (also the display)
Do you have some ideas to how to fix this issues?
My english is not very good, i hope you understand.
Thank you in advance for your reply

    Could you check the soldering around RR10 (resitor network next to the encoder)
    Maybe you have a cold solder joint there.
    Without the network the input pin is floating (no defined state)
    so it could explain the flickering/blinking when you approach the button with your hand and would also explain a hanging button.


  • Thank you very much Julian! You are brilliant! Now everyhing works fine!  I love my new lxr. I hope you will continue to develop assembly kit of making sound machine!
    I wish you a nice evening!
