Help for Buttons

All electro-mechanical components subject to wear by abrasion of the contact surfaces.

At some point it starts that your instrument dos not react each time when you are pressing a button. Then you start to press harder on the button, or you can press something right, or something from the left. Somehow the button reacts after all. Some time later it is just luck if button react ore not.

It does not help. The buttons are simply worn out. On the contact surfaces no conductive material is no longer present.

The only sensible solution is to exchange for new ones.

My tip:

exchange directly all button. All buttons are the same age and when the first one has unreliable function soon it will be in almost all button. Most time in this work you need for the srew on the device. The soldering itself goes quickly.
