Recently my rfm started ejecting two balls. In the test menu I noticed that trough ball 1 switch wasn't working.
I used my cell phone camera to look at the emitter side of the opto board and noticed the emitter was not glowing blue. I replaced the led emitter and hooked it back up but it still isn't "glowing" under my camera. I thought maybe my soldering job on the led sucked but I check continuity and it buzzed. I also checked continuity from the motherboard to the opto thinking maybe there was a break in the wire but that too buzzed.
Now that's about as far as my limited repair skills can take me. Any ideas on what I should check next?
