Dead opto switch world poker tour

[RudeDogg1]

I've reseated these a couple of times on the CPU board @Moonraker never seems to make a difference.
still all good for the time being.

cheers @cooldan, made me chuckle

Change them to molex

Change them to molex

dumb question then. that would involve desoldering the current board connector and swapping out for a molex version?

 

[RudeDogg1]

No the connectors in the above would be replaced with molex connectors so cut off pins fitted and new housings

I have new parts for this pinball, but not listed on my website.
I can bring them to NLP if you know the part numbers etc.

There is a locking mechanism on this game at the back of the mini playfield. Three light emitters on the top (all working) two receivers on the bottom. When you trigger the outer receiver, the bars lift. When the ball passes into the lock mechanism and triggers the inner receiver, the bars fall to lock the ball. You can just about make out the 2 receivers here, the are on one little circuit board

The solenoid side of this, the mechanism that works the bars, is fine. I have run the switch test and it is the inner opto receiver that is defective

What is the fix for the dead opto receiver please ? Do i just buy a new opto for it ? Or do i need to buy a new little board with both opto receivers on it ?

I have never fixed an opto board before. This is in a really difficult spot at the very rear of the game, so hoping to fix it in one go if at all possible

Thanks

Sorry to revive this old thread but did your dead opto cause the bars to jump up and down intermittently? I’m hoping it’s just a bit of dirt on the upper playfield interfering with the sensors. All lights appear to be on the bottom. Is there a way to run a sensor diagnostic in the service menu?

Sorry, but it is so long ago I can't remember.

My game also had a more fundamental problem. A drop target bank reset bar had rubbed against the wiring loom and created an intermittent short. This short put high voltage (probably solenoid) into the opto circuit. This just devastated optos circuits all over the game and all manner of madness ensued.

Sorry to bring back those memories- yeah I’ve read up about that drop target fault too on other people’s games- think Stern put out a suggested fix retrospectively. Not much good if the wires were subsequently damaged. hopefully it’s a simple case of checking for dirty around the sensors on mine
