In the process of retro-fitting my #Flight2000 with the LED lamp adapter kit, I have lost 2 of my insert lamps. I replaced the lamp sockets and the bulbs but they are still out, telling me the issue is probably closer to the lamp board. I have a multimeter but I don't know where to start to troubleshoot this.

Also of note: when removing the LED adapter kit and re-adding it again, I noticed both lamps came back on along the way at some point, but now they're off again. What should I test to see where the fault is?

wiggle the connectors on the lamp driver board , could be a cold solder joint or a bad trifericon pin

Sometimes it is the simple things that are the problem and often overlooked. The connectors could be failing, have cold solder issues or the like. I would start there. If they check out, only then would I break out the dmm and start checking traces, diodes, scr's etc.

That was it - just a loose connection. I really wiggled a lot of the connections till it finally came on. Might have actually been a wire too, thanks guys!
