8 LEDs permanently On

Post by muffinman »

I have 3 blue spokePOV kits. The first two worked beautifully.

Now, the third, not so much.


Seems like once the spokePOV receives power, every LED connected to latch "IC10" illuminates. I checked the hardware, there are no shorted leads, and everything looks mechanically fine. Is is possible that that 74HC595 latch is faulty?

A faulty latch is possible - but highly unlikely. Let's rule out some other possibilities first. Double check the solder joints and component placement. If you post photos of the front & back of the board, we'll have a look too.
