I can’t really see how you have your S4, 5 and 6 pads wired that may be the cause of your non blinking LED it sounds like it may not be grounding correctly

I’m still a little confused so just to be absolutely clear

Currently in or out of the box it doesn’t work

It did work except for your LED not blinking when you changed the depth pot, check nothing can short on the bare metal enclosure and you haven’t accidentally pulled a wire loose I’ve assumed your LFO works but

To check the LFO is still working with the speed pot at minimum IC2 pins should fluctuate between around 2.2v to 6v, set at maximum around 3.7 to 3.74v except pins 4 and 8 ground and power
