Damn GI....
Silverball84:
I apologize for inaccurate info. GI power doesn't get rectified it is ac power. However being a standard bump Target tells me that touching that mounting screw would short nothing. It mounts directly to the wood. The leads in the picture look securely fastened. If anything in this problem is related to a short check your led 47 bulb. If the socket would have shorter to a switch chances are it would have killed the switch matrix...thus preventing the mpu from even successfully booting. I never got in to the whole pin led thing. I like the nostalgic look. If everything checks good go back to incandescent bulbs in the GI. See of that solves it.

No need. You appear to be able to handle the issue yourself. 8)

I'll get some better pictures today and put something together. I agree though, technically it shouldn't have shorted anything which is really odd. I haven't heard back from the board tester yet so I'm sort of just in limbo but the feedback is great. It certainly helps think through the solution.
As I think back, on the very first day I got the machine I noticed that the light in that bumper didn't work but everything else did... so I did a bunch of things, then replaced the bulb and then I heard a pop... the F5 fuse blew. Hence why I was wondering why it didn't blow. Anyway here's where it might get kind of interesting.... because I was a new I didn't know what was going on or how to disassemble right? So I took out both bumper screws and then realized I needed to do a lot more to get it out. Lifted the playfield, noticed the fuse, replaced it and it all worked... replaced that bulb and it worked. Put in screw one with no issues... put in screw two and when I got to a certain depth the light would flicker so I stopped. I'm not sure why I'm recalling this now but I was thinking... why would that piece have touched the light... well it's because I didn't put the screw all the way down.
It doesn't fix the issue or help me understand it but it does confirm that for some reason that screw did something ???
Silverball84:
The only reason I can think to cause a flicker would be just bumping the socket and due to its age its probably not making the best of contact with the light bulb. I will suggest to turn the power off when removing or installing parts. Just reduces risk for accidental shortage. Just wait to hear what the board company says, and go from there. This should be an easy fix.
Toadie:
So I spoke to the board guy today and he's fixing the board but he couldn't say why the fuse didn't blow. He said I was right though that fuse F5 should have triggered. He said that he could follow the trace and verify it?
