I'm dealing with my Fire not getting power to the board. I've tested the power supply (probably wrong) I'm very new to this so even with the manual and numerous threads I still find this challenging.

When I turn it on all the lights come on and I hear the speaker hum but my leds on the board don't come on nor the displays. A while ago by mistake I jiggled the AC in (12 pin waffer) and it came on briefly. Thought it was maybe those pins so I replaced them and nothing. Removed the power supply and tested the capacitors and resister and all look OK. Looked for cold solder joints on the power and main board and all ok. I've tried just plugging in IJ18 and still nothing.

Checked fuses about 5 times all OK. The game was working but just suddenly stopped. No power surge etc... I've noticed the 12 pin AC some wires go under the playfield, are they going to something that could have blown?
It's been almost 2 months of constant research and I can't find the issue. Like I said I'm kinda green so It could be obvious to you guys. Help.

I tried that as well. Still nothing.

OK. After going back to the schematic this makes more sense. I guess if IJ17 is pushing out the right voltages I'm OK as far as power supply right?
