we have this panasonic cordless phone (i donno what its model is but its so famous and very good too) which buttons got so low-response to use and you have to push so hard to dial a number or turn it for talking and what.
So I'm decided to open it and fix it but with the knowledge I have about buttons, their plastic inside them and the PCB, I have no clue what I should there or what to clean, What do you think, do you think PCB is got filthy? its rare since there is no opening on the phone itself to gather that much dust.
strange thing is that all its buttons (atleast the most frequently used ones with some rarely used ones) got just into this problem but its flash key or redial is fine, maybe a design fault since those two buttons are different in design and are smaller.
