Button failing
 

Hi everyone.

One of the button on my out-of-warranty Virus C is not working properly. The Value / Program + doesn't respond all times I push it. All otehr buttons work like new, Value / Program - included. The sound when I push it is exactly the same as other buttons. Seems like some dust in the button or stuff like that. Sure there's a simple solution for this.

What can I do? Any suggestions?
