I recently purchased a 5m long strip of ws2801 leds. I've been trying in vain to get them to light up. During part of my troubleshooting I decided to confirm that I was getting power across the strip and to my surprise I wasn't! I adjusted my set-up to power the strip directly (there is a bunch of 4 cables for data, clock and power and two additional cables also for power). Now some of the lights come on but it's clearly not working correctly.
I removed the cover and it looks to me like the strip I received isn't wired up correctly, I was wondering if someone more knowledge than me could confirm? I've attached a photo of what it looks like. I've been treating (from the bunch of 4): red as ground blue as positive yellow to MOSI green to SCLK
but as shown in the photo yellow and green are soldered to the same point. I would have thought blue and green should move up a space!?
Thanks for any help!
