Led strip section not working?

I got a Led strip and a section of it doesnt light up blue but it lights up green and red. Also any variant that requires blue for a colour shows as that variant, EG Cyan on the one half but green on the side that does not show blue and another example, Purple on the one half but red on the side that doesnt show blue. HELP!

I have the same problem. 1. Sometimes the problem area is a 3 LED section between cut lines. The sections that follow it in the same strip are fine (in this case I suspect it's a faulty section?) 2. Other times the entire strip segment is only displaying 2 of the 3 color channels (I suspect it's either a bad connection or a faulty contact point at the end of the strip? Not sure which) 3. Then at other times it's a 3 LED section between cut lines that only displays 2 of the 3 color channels, with the rest of the strip showing all 3 channels (I suspect this too is a faulty strip section?)I'm getting into LEDS for the first time so if anyone could speak more to my problems, man that'd be awesome!

By section is it more then a single LED ?

I have had this happen. One one the three colors does not work anymore. It could be because of a bad connection to that one color or something in the strip wiring not making connections anymore. You could experiment with it by getting a long test wire powered with 12 volts taken from your controller and work your way up and down the strip touching the wire to the connections for that color and try to isolate the bad section. Once you have found the bad section of the strip just cut it out and then connect the ends together. Or you can just leave it in and let it do it's own thing and appreciate the diversity.

By the way, I have been advised that part of the problem might be because of buying cheap LED's. That may be the case but the price is so much less that throwing out a few defective ones is still much less than buying the super high quality ones.

The most obvious thing would to replace the broken LED....
