Cyc light pixels acting up

[PrettyFlyForALightGuy]

Hey so we're working on a fairly large production for the venue we're in. We've got a bunch of cyc light bars. One of them has two pixels that flicker different colours randomly(no consistency). There hasn't been any actual pixel mapping just whole fixture control. What would cause this is issue? What are a list of options to troubleshoot it? Thanks in advance.

We used to see this wih some LedJ battens we had - the batten is divided into sectors and sometime a sector would flash. We first started by checking and resoldering the joints on the boards - we found one or two that were shonky - which made a difference, but we still occasioanlly got flashes. Turned out to be down to cabling and termination - some of the XLRs were a loose fit, and one of the runs had a terminator missing. Replacing the cables made a big difference, but it was when I argued that we really should terminate everything as it's not optional that we finally got stability. So that would be my check list:
1) Terminators in place and undamaged.
2) Cabling is good and all connectors are good.
3) Look for bad solder joints in the fixtures.

It would help if you could tell us what Make and Model the fixtures are, how they're powered, and how they're cabled.
