Hi everyone and congratulations for this wonderful forum.
I Have a Bram Stoker's Dracula pinball machine that has a strange problem with some opto switch.
When I turn on the machine, on display in the test report, appear the messages "Check opto 73, L. Entry Lane" and "Check opto 56, T.L. Popper".
Furthermore, i heard a solenoid noise that continues to pop a little bit more than normally (maybe it's the 56 popper...).
The strange fact it's that after 2-3 minutes, the switches works normally, like they need the machine to "warms up"...
I have noticed that in the matrix of the Single switch test, the switches mentioned blink for 1-2 minutes and after this time they "stabilize" themself and work normally.
Which type of issue it is? How can I try to fix?
I hope you can help me, we love this machine in our family, because it is a gift of our dad years ago.
Sorry for my imperfect english.
Thanks and Happy New Year to everyone.
