Jurassic Park (Limited Edition)
Stern, 2019Hi All! Has anybody else had problems with the opto board for the jeep? My second one has just failed and I am having trouble finding one. The part number is 520-8102-00. This opto board is directly underneath the playfield jeep and senses when the jeep swings left or right. Has anybody fixed this opto board perhaps. Stern has them on backorder and I can't find a distributor that has one in stock.
Any help would be greatly appreciated!!
Hi, same problem from my side. T-REX letter enregistered randomly without touching the newton ball. I suspect this card. Let me know if you have somme good adress for getting this card. Lionel.

Sounds good!
Quoted from pinopinballmods:RGAires, when you say resolder the contacts could you indicate which one on the card ? The four by each opto ? In total the eight ?
If you can indicate me on the picture I made, the correct contact to resolder I appreciate your help. Regards.

Yeap thats it my friend, in my machine, that was the issue
Same issue here. Like others i'll try to resolder first
Added over 2 years ago:After resoldering, same issue, i guess my opto is dead. Does someone knows what kind of opto they used to build that card (i can't find schematics) ?
