Hi, Im fixing a Xenon with a very strange problem in the switch matrix:
The only switch with problem is the outhole, in test mode works fine until I closed the drop target #1 switch in combination with another sw of that column. If I do that, the sw outhole shows tilt or spinner or 1 ball release.
For example, if i hold outhole, and drop target 1 and drop target 2, the display show tilt as closed. Then if I release the dt2, and hold #1 button, I get "lower side target" sw on the display. This only happens having drop target 1 down. If i realease drop target 1, outhole switch works ok.
I changed the mpu and driver and I have the same, so is no the board. Also I checked all of the diodes on columns and rows involved. I also cut all the capacitors.
I dont know where look now. thanks
