nbpatton Posted September 29, 2017 Share Posted September 29, 2017 Hoping someone can help me troubleshoot an issue I am having with the Lumia 5.2s. My setup: I have 2 makers heat sinks with 2 lumia 5.2s each. Each heat sink has a makersDRIVER 5 up to control the 2x lumias. The overall configuration is controlled by a makersLED controller. I just built the fixture less than 6 months ago. Within the last few weeks, several channels have gone out on one of the heatsinks and I just have blues. The other heatsink is unaffected. While I like giving the fish the option to choose between night and day on the two halves of the tank, it is quite unsightly. Since the entire heatsink is having issues, I assumed the problem was the 5 up driver board so I ordered a new one. As I was about to replace it, I decided to test the voltage on the board. I realize the PWM signal won't give me an accurate voltage, but this was a Boolean test - is there voltage or not. To my surprise, I have readings on all channels at the output of the board. Now I am perplexed. Does anyone have any suggestions on additional tests to troubleshoot the issue? Link to comment
