Hi,
I have a 200 APA102 setup behind my TV. All the colours look very accurate except when the screen becomes fully white. The leds tend to get orange. Partial white screen works fine.
I guess this is a power issue but, before I start tinkering I need some advice.
I have a power brick rated for up to 130W at 5V. I put it a bit higher then 5v for more vibrant colours (5.4v). All the power cables are 1.5mm thick. I've connected the power to both sides of the strip and my guess is that that is the problem because the PCB is fairly thin and I think it can't carry enough power to turn all LEDS on.
- I can't seem to find how much power 200 APA102 leds would consume when fully white, is 130W enough?
- If I would attach more power cables throughout the LED strip, is it better to interrupt the power cycle and power every few LEDS on their own or can I just attach them in parallel?
Thanks in advance.
