WS2811 strand won't come on

[ttwiss]

I'm hoping someone will have some insight for me.  I have one wreath that I have 100 ws2811 pixels on that won't light up.  I am running it off of a sandevices e682.  All of the rest of the show is working except this one wreath.

- Tested the output with another wreath- works fine.
- Checked the fuse- OK
- Tested straight from the sandevices interface- does not come on (all other outputs come on)
- When I first connect it- all the lights flicker so I know it is getting power.

Any chance the pixel data chip is bad on the first pixel??  Any help would be greatly appreciated.

Or could you be connected to the data out side of the string?

I've seen it be several things.  Yes it could be a bad pixel.  It could be miswired from the manufacturer.  I had one string I saw work this weekend and then after troubleshooting something that string quit working.  I cut out a couple pixels and it still wouldn't work so I can only assume I fried all the pixels somehow.

I don't think I'm connected to any other data out side of that string.  I switch the input plugs on the e682 and no lights to the problem strand.

Yeah it worked just fine when I tested it before connecting the whole display.  I can't figure out what happened!

I think I may have figured it out!  I replaced the european connector to the e682 and it works again.  Perhaps it wasn't connected properly there.  But now it works.  Now I have to redo my connections that I took apart testing everything. But it should work again!
