I've got 3.35 V on pin 2 and 5V on pin 3. Normally, that works fine. But at the output, 0V. So I think that the LM393 is brown.

Howether, I'm looking for this strange voltage on the input 2 of IC5. I think there is a mistake on the Clone PCB. Because the voltage divider looks like to works fine.

I will contact the PCB maker to have the layout picture to check where the trouble come from.

I'll keep you in touch
