f4v only outputting 21 pixels

[thewinks]

I have a new to me f4v and I am trying to get it tested.  I have updated to the latest firmware and now when I try to test the pixels with just a single string of 100 pixels attach only 21 pixels will light.

Port Config is attached.

I don't see anything wrong with your config page.  Are you sure that the pixel string is fully operational?  Pixels can and do fail.  One of the common failure modes will result in all pixels after the failed string not working.

That would be my first guess.

yes it was a bad string.  This was a never used string so I had thought the problem was with the controller.

No one like a bad string, but at least you identified the problem...
