I wonder if someone can describe how the LED meter in the attached works? It's a strange arrangement, difficult for me to understand.
My issue is that I have some LEDs in the meter that do not light. I actually made it worse by trying to apply some voltage to some to see if they would work or if it was the driver at fault. So there's that. Now only the top three LEDs in the stack will light up.
I got a new IR2E19 chip, and saddled it over the existing one to see if it would make any difference. It did not.
Any ideas?
Thanks.
