So you have 3 power supplies and the issue is spread across all power supplies, if that is the case then it looks like just bad quality which is a shame and very annoying, but 13 volts is a tad too high as a 5% deviation is the most i would have
It wont be the power supplies if the issue is spread across all 3 unless there is an inherant design issue with these power supplies that is putting a large volatge spike into the lights when it is powered on and thats why you see so many failures, but im doubting thisNick Cosper said:What should I do to figure out if it is the power supplies? Anything short of replacing?
They are ziptied to 1/2" pvc. Originally I did have them too tight, but have since loosened everything and this problem still occurs. I was having regular solder breakage of splices but since I loosened everything I haven't had any.ShellNZ said:Are they ziptied to something? If so, zip-ties too tight?

Take a look to see if its not a resistor that is having an issue for the red , try pressing around the section that has failed and see if you can get the red to come back on, if it does then you know its a solder issue
I have tried this in the past and it does work well if its just a dodgy solder jointDavid_AVD said:I haven't had a chance to try touching up he LED solder joints yet.
The resistor is not something that normally would go bad, it would be the soldering or the LED itselfNick Cosper said:Fasteddy said:This is more looking like bad LEDs because the issue is only really associated with the Red.

I'll give that a shot tomorrow. I'm curious, if the resistor is whats failing is that something that I could just replace, rather than replacing the section of strip? Or does the bad resistor cause the chip to go bad?
