I meant the connectors before the flat ribbon cable. There are these tiny small bridges just before the cable and they have this tiny black thing that connects the two soldering points. One of these are broken.
Thanks for the tip with the cable though!

I'll try to make a sharp photo like the other one without the grid later.
What I just discovered, while removing the grid its seems that I broke one of the connections to the ribbon cable.
The very last on the bottom. You can even see on the blurry picutre. What is this black pin that most connections have and is it some sort of resistor or could I just remove it and repair the connection with some normal solder?

Thanks! That actually helps

Interesting to know! Thanks!
I removed that grid thing and it actually looks more like those buttons are just photoresistors. The grid holds all the buttons which are nothing more than transparent plastic bits.
I couldn't explain it myself any diffrent than that the buttons react to light as I somehow doubt these things measure heat?

I guess you are right about the keyboad thing but I'm still not sure how that would be connected to an arduino :/

Its hard to see if there is any seperation or not, atleast for me :/
The user interface on the other side has 9 buttons which corrspond to the Tx marks on the back.
The white frame you can see has some sort of sikicon blobs that are "connected" to small bumps on the PCB, I guess its measures the temperature to detect if the button is touched?

Also interesting to know that this is/could be considered a keyboard. Where exactly is the diffrence in the defintion of a keyboard and a touchpad? Does a "real" touchpad has to send x,y values instead of something like "button x" pressed?

I dissambled an old LG Media Player and would like to reuse its 3x3 touchpad.
As I'm still quite new to Arduino and interfacing with electronics in general, I'm not really sure how I can approach this.

The touchpad has a 10 pin ribbon cable with Ground and VCC marks (even though I'm not sure which of those tiny lines is what now).
I would be glad about any hint on how and if I can connect this without any extra hardware to my Arduino UNO.
