Quoted from zaterminator:
Checked, all the connections are seated well. Here is a pic of the board. Right side on sparky up top has no light, so it appears that is my problem. The gravemarker IR is fine, just Sparky is out.
The specific connector on the control board there that you are interested in is J1. Pull it off completely and reseat it. The LED indicator IS on, so at first look it looks like it is seated ok, but that LED will stay on faintly even if the connector is removed, so it's worth a quick check.
If that's all good, swap J1 and J2, and the left opto will become the emitter. It does work that way around. This will tell you whether the right opto is completely blown, or just won't emit.
If the left one doesn't light up when swapped, you may have an issue with the controller, if the switch doesn't register but the left lights up then I'd say we have narrowed it down to replacing a bad opto on the right.
