Didn't help (didn't have time to try anything else though).

I'm going to dab the legs on the timer IC even if they all look nice and clean. I doubt it will work but I have nothing to lose.

If that doesn't work I'm thinking that maybe the hole for the OSC is not done right, maybe it was supposed to be a via but no signal is going to the top layer.

I'm going to try to remove that 4MHz osc and check the inside of the hole (and continuity if there are pads on both sides). Then solder another one back with longer legs so I can solder both top and bottom.

After that I don't know what else to do except take it skeet shooting next time out.
