    I've had two led strings fail. They have both failed at the join on the metre marks. One was 2m from the input end and the other 1m. I thought that having them both fail at a join (manufacture joint not mine. These are new and I haven't changed them at all) seemed a bit of a coincidence. The joints are made by overlapping the strip and soldering the two little connection pads on top of each other. So I thought I'd see if it was a joint problem. I carefully cut away the silicon and soldered a bead from the end of one strip across to the other (only tried to fix one of the failures at this point).

    I then connected it back up and now I have two strips that go to the 1m mark. So I lost another metre of strip in the process. Doing well so far!

    This is the strip I have. http://www.aliexpress.com/store/product/5m-DC12V-INK1003-led-pixel-srip-IP68-30pcs-1002led-5050-RGB-with-bulit-in-INK1003-IC/701799_1546255452.html . It says it can be cut every led but when I ordered it ray did tell me that he could only give me lengths in multiples of 1m.

    Does this mean with ink1003 when you have a failure you lose 1 metre or is there a way of finding out which led failed and then just replace it and the one before to fix the problem.

    Thanks

    I lost a meter and half on 2 strips when I messed up a solder job or two. I was able to pull the dc dc convertor off one section I thought was bad and get it going as a passive section backfed by another of the DC sections.


    You might try a 5v power supply and that's what does not cross at the borders at 1m.
