Put this in the "I'm sure it's been asked a thousand times" column but, anyone got any idea why I have 6 pixels lit yet nothing being sent from the controller?

I think it has something to do with a channel issue but can't find anything on here (not using the correct search term).

Running this string off a smart receiver connected to a falcon f16v3. Have replaced the string and changed the port but same issue.
 
Data wire into DO when it should be DI?? Have you got minimum 5.3V powering the smart receiver?

Can confirm the 5.3v on the smart receiver. Rest of the string and 2 other attached seem to work ok.

Have tried another string with another pig tail and it does the same thing.

Interference making lights flicker and change colours

Hi, this may sound stupid to some experienced people on here, but thought i would put a post up for all the others. This is my second year doing RGB lights, and i had a fairly good display last year, but some of my props/models had some lights changing colours and flickering when not suppose...

Is the controller on? Does it all work in test mode?
Pixels will light on certain strings etc if no data is received to tell them to be in the off state.
Make sure your ground wires are connected properly and if you are running ground from a different point, ie from a controller and power direct from the power supply, make sure the grounds are tied together.

Wasn't that minimum 5.3v changed to be 5.0v ?

Yeah maybe, I haven't opened my new ones from this year yet. When I went to run a small show for Halloween this year I started up one of last year's receivers from a plug in 2.5amp PSU and the receiver didn't work, so I looked at the manual from the falcon site and it shows that the minimum is 5.3v still.
 
Possibly the controller config has the port expanded into smart mode but the receiver is in dumb mode

I thought I had read that David was implementing a Smart Receiver voltage spec change too but an ACL and Falcon Forum search did not show anything. I recently received a pair of v1.03 receivers which has a LM2937ET regulator. The LM2937 is a low dropout regulator and with no method on the board to bypass it, it would appear the 5.3 volt spec remains.

This is what it ended up being - I have the receiver in dumb mode but had it mapped to Smart Receiver A in Xlights - moved a single dip switch and all good.

Clearly a PEBKAC error.

Note to self - don't do a full days work then extra hours on lights or you end up doing stupid things......
