UP Button doesn't work

I have a problem with my MintyPi and need help.

My UP Button don't work. Everything else works fine just the UP Button don't work.

I test the connections an soldered also the Testpad directly to the GPIO from the Pi and still dead.

Is there a way I can connect the UP-Testpad from the PCB to another GPIO from the Pi? If yes wich one?

Or is there another way I can make work the UP Button?

Thank you for your help!

Easiest way to test the up is to take that wire soldered to the GPIO and remove it from the UP pad and touch any gnd pad to see if it works, it does then there is likely a broken trace on the UP. We can trouble shoot it once you verify that touching GND with that wire makes UP work.

I tried, but still doesn't work.

No you don't solder it to the GND you just touch a GND point while the system is running to see if the Up direction works, the GPIO buttons only register a button when it touches GND for a second. The way you have it now the UP is constantly being pressed in.

ah ok, now i understand.

when i touch a gnd point an press the UP Button it jumps straight up to AUDIO in the Menu.

Ok so now we know the GPIO code is working on the Pi now let's test continuity from the UP test pad to the UP button pad on the face of the PCB. Basically these 2 points below:

I checked it and there is a connection between these points.

So if there is continuity (arrow symbol with a +) between the 2 points I indicated then soldering a wire to that test pad from the GPIO that is up should be working. Double check you're checking continuity as I had someone tell me continuity was good but was using a different setting on the meter.

Wich setting on the meter is the right one?

Still doesn't work
