Yamaha PSR-18 Keys Not Sounding
Some keys on my PSR-18 do not sound. I can get a sound from them when I press hard or press at about the middle of the key. I suspect that there is a problem with the contacts. I have tried an air spray but that does not make a difference.
If I were to take the keyboard apart would I be able to access the contacts to clean them or would they require additional work e.g. new coating or replacement. Has anyone had experience of this model and problem, and can give my some tips?
