6 button on keypad intermittent

2016-06-04 by neil.macneil@...

Hey folks,

I'm new to the group, love it so far. I've been modding my 800 mk1 with moog slayer, fm 800, etc. A problem that I am seeing is with my 6 key on the keybed. It intermittently works. I'm reflowed solder over all the components and even replaced the 6 key button with a working one. It seems if I keep pressing the 6 key and put my other hand over the bed of resistors on the edge of the board the 6 key starts to work again, sometimes for long periods.

Any clues as to what might be wrong, i'm pretty new to electronics repair. I have a multimeter but not sure how to use it to check for bad traces or connections. Any help would be awesome.

-Neil
