I've got a weird situation happening with part of my display. F16v3 with expansion board. Driven by 4 - 30 amp PS's, 1 to each side of main board and expansion. All 4 running right at 12v. This just started in the last couple of days. I noticed when out taking a pic or two of my display lit up, I noticed that a couple of props were acting eraticly. When I run a test from the controller, all pixels light up. When I run a sequence test from XL, everything works fine. But - after dark as it cools down, and I start up my display, 1 prop does not light up at all, and 1 has only 30% of pixels lit. I checked and retightened the cables. Anyone else experience anything like this?

I have one output that seems to get worse when its colder. Its always run great for several years but this year its getting flaky like a data integrity issue. It will stop working and freeze and then a few minutes later starts working again without me touching anything.

So, I switched ports on the two props that were acting up and they worked fine all night. These controllers are 4 years old, have been bulletproof, and up until this season have not been pushed hard at all. I moved props from Port 4 to 5, and 7 to 8 and all is well. Why would 2 ports out of 32 act up?
Hey David, if you see this, your thoughts???
-
Where did you switch ports? Was it at the circuit board or the pig tail connection.
Did you attach anything else to port 4 and 5 to see if the problem continues? Or waiting until after Christmas to troubleshoot.
Could be just a bad connection or a cold solder joint causing you problem.

I changed to a different pigtail. Gonna leave well enough alone until after the season. This is a Falcon board, so no DIY soldering, but I suppose that there could be an iffy joint on the board.

Understand on after the season
I did have some solder joint on boards I didn?t like and went back and reflow them.
