I seem to have caused an issue with the CPU switch matrix circuit on my DE SW machine. The issue was caused by my stupidity as I was impatiently adjusting my pop bumper switch in diagnostics switch mode and hit the coil line.

With this I now have all of the switches activating that are on column CN8-7 at the same time when any one of these switches are activated. The issue is on the CPU board as I have tested each pin off the CPU in the diagnostics mode with a alligator test lead and 1N4004 diode. When connected to CN8-7 if I touched any of the pins between CN10-1 to CN10-9 all switches would activate at the same time.

I was wondering if anyone know where the cause of the issue may be and which components may be the problem or do I just start replacing components along this line on the board until the issue is fixed. Thanks in advance.
