Control Board woes

Building my programmer…

No LEDs lighting on control board. When I first gave it power I got nothing, then when I tried again, I got LED1 and LED7(briefly). 7 turned off and 1 stayed on. I unplugged and plugged in again, now get nothing. The filter board is good, as i plugged in the control board from my other shruthi and all worked. I plugged the new control board into the old Shruthis filter board and got nothing. I compared parts and orientation to the control board I know works, and can’t find any differences…

Scratch that, schoolboy error, which I am too embarrassed to disclose…

Strange one though, when I press button 5, it cycles between different LEDs. Seems it will cycle between the last selection and the current one. That’s not normal, right?

Incedentally, pressing button 5 will not lights LED7

Found the problem. All working as it should…

great thread!

Obviously another proof that some problems solve for itself if you just wait a bit. Must be german Postal Services Service Strategy…

Or maybe it solves if you post it here?

Yeah, this place is kind of Magic :wink:
