Hello dear pinside community,
I've purchased a Starship Troopers a while ago and since that I've had problems with some things.
One of it is, that the right loop-opto won't register a ball when it is rolling through.
I checked the opto assembly and the red lamp is always on (receiver side). It is supposed to only be on when a ball is rolling through. I could tell because the other loop works fine.
I bought a new receiver board but it hasn't changed anything. (red lamp still always on)
There are no obviously broken wires. (I did just roughly check them)
I do notice that the light beam of the emitter is slightly above the LED of the receiver (look at pictures). But even if I hold the light beam in front of the LED of the receiver (by hand) the opto still won't register (red lamp is still on).
Do you have any idea what could be the problem and maybe what could be a solution?
Any help is greatly appreciated!
