Quoted from Mr_Tantrum:
If other lights in the same column and/or row on the lighting matrix work then it is not a fuse. Most likely either a loose wire, a bad socket, or a rusty socket. I would recommend the following:
DO ALL OF THIS WITH THE PIN TURNED OFF!
1) Make sure no wires have come loose from the sockets not lighting on the underside of the playfield. If not, proceed, if so then solder them back on
2) On the topside, remove the bulb and take a small piece of steel wool, insert it into the socket, and rotate back and forth several times to clean the socket lead
3) Make sure you are using a bulb that works in another socket, and try it in the socket not working. If does not work, remove, rotate it 180", and re-insert (some LEDs only work when inserted in correct orientation)[quoted image]
So I found one disconnected wire (to the shoot again light). Fixed it and shoot again works now.
The ones that aren't making sense are the ones on the mode lights. Underneath all the mode lights are on the sane board. Yet extra ball, stampede, and 1 smart missile don't work. I replaced the bulbs and then I exchanged a socket I knew worked with one that isn't working.
When I put the one that I know is good in a spot that isn't working, the light still doesn't work and the socket that wasn't working is now working in it's new location.
Can it still be a broken wire since all the lights are working on the board except the 3? I've tried reseating the wire to the board but nothing.
