Bulb good ? Metal clips inside the socket that grab the bulb good ? Power at the socket ?

Hey Ninja
One way to isolate a board problem from a wiring/connector/socket problem/playfield problem is to put an alligator clip w/lead on the metal tab of TIP 102 Transistor Q 14 (associated with Blu-Org). (Sol/Flasher Table P 2-46 in the AFM manual)
With power on, momentarily touch the wire to ground (side rail, .....) Don't get shocked by touching any bare wires or ground.
If the flasher lights, then wiring, power to flasher, connectors, even the trace on the driver board to Q 14 is OK. This would further indicate a problem with the TIP 102 or it's pre-driver or other board problems.
If the flasher does not light, there is a wiring, connector, socket, lamp, power to flasher, or other playfield ........ problem.
Do not run this test on the high power TIP36C transistors.

Did I miss it somewhere that you tested the socket for voltage? I see testing for continuity. Led flashers are very , very finicky. Start with the socket before delving into anything else. If you have voltage, play with the led bulb. Rotate it 180 degrees and reinstall it.

Every time my flashers have gone out it turned out to be the socket. I took the sockets from old ramps I had laying around . I would remove the rivets and install the socket to the ramp inside the machine giving me the issue. The sockets seem very temperamental. Actually this happened on my AFM but the socket location I replaced was on the right ramp.

Pinball Life sells new ones. No problems for 20 years again.
