I just got the all in 1 IN-14 kit. I love it and have enjoyed putting it together. There have been a few issues I have ran across. The first is when I finished the low power section my LED would not light up.I pulled it and swapped polarity and it still did not light so I used a different LED and it worked so I guess I had a bad LED. (Not a huge issue) But now the RGB LEDs remain red. I went through the forum and found another person with that issue so I tested all the test points and caps. All Vin points show 12v, all VCC are at 5v and all 170v test points read 170v. I tested polarity at ground and they are all good. So before I attempt to see how good my engineering skills are I thought I would reach out to you and see if you had any other places I should test.
