Liquids on digital piano keyboard — Pianoconcerto Forum

Hello everyone, a question

Aside from the fact that I probably don't understand much about these things, I would like to try to understand if it is possible to do something about it, if it is possible to intervene to solve the problem or, unfortunately, there is little to be done...

Alas, last night I was preparing to practice a bit on my digital piano and I had the brilliant idea of placing a glass of water (full) on it; accidentally, this cursed glass spilled completely on the piano and the liquid went "inside" the piano, passing through the "spaces" provided between the keys of the keyboard itself...

I promptly tried to eliminate everything, the liquid part let's say, using paper and even a hairdryer, to try to dry everything; I spent about 10-20 minutes trying to resolve the situation or limit the damage as much as possible, but I did not get the hoped-for result...

The keyboard of the instrument does not properly respond to what is pressed or played; things are simply like that

I am asking you, in your opinion, "opening" the instrument, unscrewing everything and trying to change the damaged electrical parts inside, can the problem be solved? I am simply asking, in your opinion, is this feasible? Has anyone among you had experience in this regard or found themselves in a similar situation and through the replacement of some parts or other interventions managed to resolve everything?
Obviously, all of this would be carried out by personnel capable of replacing the defective parts; the piano is out of warranty...

Thank you very much for any kind of response regarding this

If it's just water... I suggest you wait for everything to dry... seriously. Unless something has "short-circuited", the instrument should return to playing normally. I would wait at least a week in a dry place.

I do not agree at all. I am sorry to be reading this only now because there is probably nothing left to do to solve the problem.

When water falls on any electronic component, the most sensible thing to do is certainly to immediately disconnect the power and absolutely NOT wait for the water to dry on its own, but rather to promptly open the device and dry it with paper, rubbing appropriately on the electronic components and eventually blowing even the smallest particles of water with compressed air. The risks of water are not solely related to the possibility of short-circuiting the electronic components, but are mainly due to the fact that as it dries, it produces oxide. Oxide is a very acidic substance that corrodes the tracks of the electronic board and the electronic components themselves. If oxide has already formed, it is necessary to immerse the electronic board in an ultrasonic bath with a specific anti-oxidant liquid for electronic parts, then reinstall the board and try to power the circuits again. Clearly, the longer the exposure of the electronic board to oxides, the lower the chances that once cleaned it will return to working correctly.

It also happened to me that water got inside my digital piano and I also had major problems. Some keys on the keyboard no longer worked. To solve this, I had to bridge all the broken electronic tracks, a job that took up a lot of my time. Somewhere here on the forum, I had also posted some photos of the operation. Now it is perfectly functional again, but the reason is that, in my misfortune, I was lucky that the liquid did not end up on the eeprom and multiplexer which I would not have been able to replace, since they are programmed in the factory for that specific keyboard model.

So, never sleep on it!

Thank you; unfortunately, some time has passed and I have had a lot of work to do, so I haven't been able to find a solution; the situation, however, as one might imagine, has not changed.

I would like to search for shops in town that can help me solve the problem, otherwise, unfortunately, there will be little to be done.

Very kind of you anyway for your detailed response, I will try to draw some ideas from it to speak with a "technician" in order to approach everything in a more specific way, for example as you wrote

Thanks again.
