Hi all,
I recently got a SMB; and I am now stuck with one last issue: the shoto again insert is not working.
It is not lit at all. If I reverse the contacts => always on
Diod is tested ok, and I tested the whole socket with diod on another insert => works fine
Knowing that it's good, that the game has a lamp matrix but no other controlled lamp has an issue, I am stuck and puzzled and what's happening here.
Any hint? 
Quoted from isJ:I don't think I am doing a great job of reading comprehension, but a lot of GTB games I have owned (smb included) have had solder missing from pads on the light boards. Follow the traces and maybe check that out?
Hi,
Thanks for the feedback
What are you calling a light board? The small pcbs holding the diod?
If so, the socket (including the pcb holding the diod) has tested ok on anothet insert.
