Hello, is there a way to fix this ?

 

What is the model name, please give us the full name and model number.

 

I will also go with Maybe, but probably not by you. it also looks like a lot of corrosion/oxidation

 

Simple Yes

https://de.wikipedia.org/wiki/Leitlack
(Da die Beschreibung auf dem Bild Deutsch ist schreib ich hier auch mal deutsch
Wie fiction schon angedeutet hat, kann man mit etwas Geschick und einem sehr feinen Pinsel neue Verbindungen mit einem Leitlack aufmalen
die Kunst darin ist
1. Den passenden Lack (hab hier mal einen Verlinkt) oder Lackstift zu finden , zu viel Konduktivität gibt es eigentlich nicht .... nur zu viel Lack an der Stellt was zu Anschlagslosen Tasten Aktivierungen führen würde
2. Genug darauf zu pinseln
3 Logischerweise eine Kostennutzungsrechnung aufzumachen, da die Lacke schon teilweise so viel Kosten wie ein neues/gebrauchtes Keyboard)

Ein weiteres Problem was ich da aber spontan sehe ist das auch oberhalb einiges Korrodiert aussieht daher mein Baugefühl sagt mir, dass das ein Liebhaber Projekt würde, bei dem sich die Kosten nicht rechnen würden für die Reparatur

DeepL Translation :

(Since the description on the picture is German I write here also times German
As fiction has already indicated, with a little skill and a very fine brush you can paint on new joints with a conductive varnish
the art in it is
1. to find the right varnish (linked here), there is not too much conductivity .... only too much varnish at the point which would lead to stopless key activations
2 Enough to brush on it
3 Logically to make a cost-utilization calculation, the varnish already partly as much costs as a new keyboard)

Another problem I see spontaneously is that also above some corroded looks so my building feeling tells me that this would be a lover's project, where the cost would not be worth it for the repair.

That looks suspiciously similar to the low circuit board from yamaha electric pianos, such as this:

If that's the case, it'll be more cost effective just to replace the board.

German:

Das sieht der Low-Platine von Yamaha-E-Pianos verdächtig ähnlich aus:

https://beckettsmusic.co.uk/collections/keyboard-spares/products/wf21250r

Wenn dies der Fall ist, ist es kostengünstiger, nur die Platine zu ersetzen.

 

It's a Thomann DP 26

 

I think so too, this piano is new and has never been used, I do not know which product caused this, but when I opened, there was like a corrosive product.
Impossible to clean (despite all precautions) without tearing off the conductive rubber

 

Thank you very much for the advices and the link.

You can also send an e-mail to thomann support about what you can do there, they sometimes have good tips.

I fix a loud key on my Yamaha DGX-520 digital piano. Thrilled!!
