This is an odd one. I bench tested the boards, and they are testing good. I noticed some odd switch behavior. So, I ran the switch test. All switches work great, but the switches on row 1 exhibit something odd. These are switches 9,17,25,33,41. On the chart is says row 1, but it is actually row 2 on the matric, as row 1 is the tilt ad other things connected to the door region.
If I press any switch, it will show closure, but it will then show the one below it is also closed. For example. If I close switch 33, it will flash switch 33 and then switch25. It is very odd. It only does this with this row. What is more interesting is that when switch 9 is closed, it will flash switch 9 then switch 1.
Ive tested and replaced all diodes on this row and also switch #1. Any ideas? Im stumped. Im starting to wonder if the chip reading the rows is lagging or shorted. Odd!
