Quoted from guido:I cannot chek voltages at the moment since the power driver board has a bad capacitator and it doesn't get 5V. I'm waiting for the a new capacitator. I can check the traces. If the voltage weren't right, what should I check then?
The topper lights went out on mine. I had my tech (who’s a career electrician) buddy go through the entire driver board and he replaced two of the capacitors. Everything back to working perfect.
My recommendation is to not sweat it until you get your 5V issue fixed. I am thinking that will fix your issue.
