I have a great Stargate pin. I think it's one of the most underestimated pins out there. The boss battle is intense and I've only beaten it once in the three years I've owned the pin.

Recently the right ramp stopped acknowledging when the ball goes up and through. I do have the manual, but I'm not well versed in reading it. I did see that it's listed as switch B0 (in the manual) and I didn't see anything obviously wrong on the sensor itself. I also moved the sensors around a little bit to see if the alignment was off and it never registered.

Does this board go bad? Another issue? Everything else, including the left ramp works great.

Thanks for the wisdom!

Thanks guys. I'll buy some opto's and see if that fixes it. Luckily they are super cheap!

I’m finally getting around to trying to fix this ramp. I can’t seem to find the 2 opto sensors. I posted pics of the two that I’m trying to replace. Do they both do the same thing? Is it common for these to go out? I googled this number and can’t find it anywhere? If you have any wisdom, I greatly appreciate it. I have a request in to Pinball Resources too. Thanks all.
