Key dylays sound or not sounds without more pressure

[mmarc]

Hello

On Nord Wave synthesizer (without any previous physical damage or hard playing on keys, just everyday pretty careful using for some years, always soft playing and keeping instrument in dry room) in right higher last octave F note key is suddenly damaged, not quite clear it is electronic or mechanical problem. With soft finger pressure delays beginning of sound with silence gap, which interval is not the same time each time around one-two seconds, then sounds normally with same loudness as on other keys, or not begins at all, key keeps quite, but almost always sounds correctly without delay immediately with pressing if I put more finger pressure. it looks like mechanical problem, but there is no noticeable reason for this and starting with delay also not quite clear, maybe it is some damage of pressure sensor, I'm not sure

Any advice or guide where to look and how to fix would be very helpful

Привет. Нужно разбирать клавиатуру. Я уже разбирал свой Wave и чистил контакты. Помогло на один год. Вчера опять "прострелило" одну клавишу. Буду разбирать опять.
