As mentioned in the video, if you do pixels, you'll need to solder and it's not nearly as complex as you might expect. Check YouTube for videos on how to solder.

Locating and Repairing Bad Pixels
If you have pixels - be they nodes, modules or strip - at some point you are going to have a failure. That failure could be when you purchase them or over a period of time due to physical damage or other causes. So, you'll need to have the ability to locate and then replace the bad pixel. This video shows how to perform this process on nodes (8mm / 12mm) but it also is the exact same process if you have any other type of pixel.

could a bad pixel all show as one that flashes to white or another color, instead of the steady 3 color change test pattern, and all the ones after it also flash randomly.
ReplyDeleteFor example - 134 node setup - 3 power supplies
try all 134 - w tiny pix and 3 power supplies - most flash to white randomly while trying to change colors
if I skip the first 34 (just because that is the next 2811 connector) - the other nodes work fine. Color change in test sequence. And even work with a DMX test.
So narrowing it down. I try just the first 34 nodes alone (and disconnect the rest)
the first 4 pixels cycle colors in the test mode just fine.
the 5th one flash to white every once in a while
and all the rest of the 34 flash to white all the time randomly (while trying to change colors in the test sequence)
is it likely a bad 4th or 5th pixel?
or some other issue?

If you have a string of pixels and it doesn't seem there is a clear point where the problem is occuring (such as all the pixels following the working ones), I'd recommend cutting the string in half and then testing both halfs. Then keep performing that process until you locate the bad pixels (cut in half, cut the remaining bad section in half, etc.)
DeleteI cut after node 4.
DeleteThen attached an extra 2811 3pin end temporarily - and hooked up my extra 16 nodes to these 4 nodes
hooked up tiny pix w one power supply
worked fine - demo rgb blue
so I cut out node 5
Soldered the line back together (in the field on the display, w srwap on each wire, and then a large swrap over all 3)
Worked in demo test
now working via DMX test sequence
I am letting it burn in test for an hour on the DMX sequence
I have a video of the flashing to full white randomly symptom to share.
(to help others in case they see this symptom on their fire pix string)

Excellent work there!
