Hi, i have a new issue with IJ, where the shooter keeps shooting balls non stop at the start of the game. i saw some recent threads similar to this, which advised checking F115 and F116. I checked both, and both appear visually to be fine.

I took the following photos of the switch test matrix and the ball trough led boards. I noticed a red light on the LED board, and noticed that the switch matrix in column 8 is void of squares, which I don't think is good.

I was not able to activate any trough switches during test I was able to activate switch 85 and switch 87, but not 86.

Thanks in advance for any help!!!!

I'd get #86 working first and then see where you are at. ( or new ball trough boards, those have had some repairs )

The transmitter board looks like it might have a bad IR LED.

There should be two green LED's lit and the center one is off. Usually that means that one of the IR LED's has failed. If you pull off the transmitter board and take a look at it with a phone camera, you are likely to find that the 4 on the right are not lit.

Unplug the board and check each LED with a DMM set to diode check. Red lead to round pad, black lead to square pad. If the LED is good, it should give you a reading of some form. If it is bad (blown) it won't read anything. Also, if you find one that reads 0 or if you DMM beeps at you, it is likely that the LED shorted out (and then possibly cause one or more of the others to blow.

Replace any that are bad.

Hope that helps!

Guys, thank you all so much - it appears that all of you were right! I had a friend out to help me (as I am a newbie), Four of the LEDS were bad on the trough opto board.

I think rather try and repair the board, i will just replace. I assume I should do both the transmitter and receiver boards?

Also, my friend redid the connectors. We noticed something, not sure if this is normal, but if you look at the picture, the two green lines on the left both go into the same connector "pin".... I noticed on the board, that pin one said 12v, and pin 2 said 12v, so it caught my attention that both green wires where going to pin 1, and no wire was connected to pin 2...

Hi All, just fixed this issue, and I want to say thanks to everyone who helped. Basically installed the Great Lakes Modular Ball Trough Opto boards, and all is good. Great help on the site, and GLM was awesome.

Finally, here is what I love so far about this hobby, the guy I bought my game from has been really spectacular about coming over and fixing issues that have arisen, total gem.

Thanks all!
