When you say you reflowed the solder, do you mean on the lamp board? If not do that. The solder wears down and doesn't make good contact with the twist cap.

Also check the continuity of the red-gray wire (see page 2-40 in the manual). Make sure someone else didn't put the diode in backwards, the band on the diode should go towards the red-gray wire.

Hey P,

I had the same problem with one I had. Unplug connector J136 on the driver board and see if the problem goes away. I bet it will. You will also note that if you go into single lamp test that other bulbs are on at the same time with J136 plugged in. Again unplug J136.

Here was my post from a few months ago

"Well after a long day of troubleshooting a bulb not working and a column lighting up and other lights were on I finally got the problem solved. I checked almost every diode on every controlled lamp. Tested rows and columns on board. Everything was working. Replaced the transistor on that column - still no help. Put a different board in - still didn't help. Figured the problem was on the playfield. Replaced a connector, removed LEDs, I checked almost every diode on every controlled lamp and even replaced a few (at the bulb that was not lighting esp). Nothing worked. I sort of gave up. Searched RGP and Martin from Pinbits said there was an extra connector on his game at J136 that didn't needed to be there. Went to the game unplugged it and everything worked the way it should. WTF!!!!! Anyways happy the problem is solved. I can rest tonight now."

I'm not sure but I had the same experience. Nothing made sense as I tested continuity, change connector, the pins on the light board, the diode. Finally I saw that post on RGP and sure enough it worked.

Glad I could help.

I never even noticed it was out. lol. Sorry, Tom.

That is weird. Good catch Tom.

No problem Dave.

I really can't take credit. I was just really glad I was able to track down the post I referred to on RGP.

Wow, I want to thank perryd for asking for help and TomGWI for answering this (and Martin from Pinbits of course). I was really worried I would have some major electrical troubleshooting ahead of me. I had random inserts that would stay on when other inserts would activate. Other controlled lighting would never turn on.

It turned out to be that J136 was plugged in and was creating all these issues. After unplugging J136 everything is perfect. Sooo happy, thanks again guys!

Same goes for me. Thank you everyone!! I had the exact same issue with the bad impersonator light and J136 being plugged in. All better now!
