Hi, I made a blunder while trying to save my NS3 after a water-spill and managed to rip off the soldering on a connector on a tiny circuit board. I have handed the part over to my local electronics repairer, but he didn't have much hope in being able to solder it due to it being so tiny, so I was hoping I could order a new part. However I have no idea what anything is called or where to even start looking. Any help would be greatly appreciated!
Apologies for my lack of precise terms, English is not my first language and I know next to nothing about electronics. I have previously fixed a dead key on this same keyboard with the help of a Youtube video so I was confident opening it up again and having a look this time.
This is the part in question, it is located on the rightmost long circuit board underneath the keybed and connects to the main board with the ribbon cable also shown.
I don't think you'll find that board by itself, it's probably part of the main board assembly. Where does the ribbon cable go? I would cut off the connector on the cable and solder the wires directly to the board.

For the quickest and most efficient technical support for your product, please get in touch with the distributor in your country or contact your point of purchase. They will assist you in resolving any technical issues that you may have.
That board is where keyboard calibration data are stored, but if you broke only the connectors you don't need to replace it as a whole probably, see also this recent similar thread viewtopic.php?t=26907

The circuit board does not appear to be damaged, so, if true, this ought to be an easy repair.
I used Google Lens to identify the damaged connector.
It appears to be this connector: Molex PicoFlex 6 pin 908140506
The linked page includes links to a datasheet and drawing. If you want to get it repaired, check the dimensions of the pads on the PCB and compare the measurements of the damaged connector to the drawings.
If you are satisfied with your assessment consider ordering a replacement: Distributors of 908140506
Let me know if you need any help if you decide to proceed with this.
Also:
The damage to your connector might not be too bad: It might be possible to salvage the damaged connector by straightening the metal leads.

Thank you for all your helpful replies so far! This piece seem to be solved, but I have run into another problem putting everything back together: The piano is not powering on. I would greatly appreciate your input on this as well.
Here is all relevant information I can think of:
Got the part back soldered and tested, should be working fine. As I can understand from the replies here, this part should have no bearing on whether the piano turns on.
Piano was left on for a couple of minutes after water spill. Testing the affected keys at this time gave results as: key playing the wrong note, key playing at max or min volume, key playing two or more notes, key being out of key. Then the power chord was unplugged without turning piano off first.
Water only got in the keybed and in the highest octave of a 88 key NS3, no water got in the main board area. Keyboard was partially disassembled and left to dry with a fan overnight, then fully disassembled the next day getting all the way under the rubber pads on the circuitboard under the keys. Cleaning those up and have been left to dry for a couple of days.
Everything was put back together the way it was. I connected the power cable to the outlet without realizing the power was switched to on, but nothing happened. Unplugged, turned power off, plugged back in and turned back on: nothing. Opened the top to make sure all ribbon-cables were securely connected, back together, back on: nothing.
Can I have blown a fuse (Are there even fuses?) or is there something else I'm overlooking or have forgotten?
