Jurassic Park
Data East, 1993While trying to find my controlled lamp problem. I unplugged CN4 out of Power supply board. I then proceeded to plug it in incorrectly 
(go ahead and do it, I am as well) after turning it on and finding that screw up, fixing it, they still do not work. Was planning on taking this to Louisville Expo tomorrow so I need to fix it fast.
Put "URGENT" in the topic title. That will shift this thread into overdrive and you'll get a flood of responses quick. 
Quoted from futurepinhead:I'm surprised nobody is at least taking this opportunity to make fun of me
Well, if it's URGENT - BOY WHAT A SCREW UP - HAHAHAHAHAHA!!!!
Sorry, just couldn't resist....I can't help with your problem, but thanks for letting me make fun. 
Quoted from SunKing:can't help with your problem, but thanks for letting me make fun.
That's why I am here.
I just checked and all the connectors are fine, fuses are fine. I still get connection from the PS board to the CPU. I am about to swap out the PS board with a spare I have just so I feel I am doing something. Any input is of course greatly appreciated.
OK replacement PS board is of no help. Any ideas, the transport vehicle is coming in about T minus 3 hours ... crickets.
you may have blown the chip that controls them by plugging it in the wrong way. That's my guess.
But wait...you tried another board with no help so thats not it.
so the problem is with the wiring at the plug.
Recheck that plug and wires..spacifically the wire that carries the power
The wires from the PS to the CPU are all fine, so should I check CPU to lamps? What about crashing something on the CPU?
I just went through all the lamps in test mode so it is not something in game play that crashed.
Quoted from wesperron:But wait...you tried another board with no help so thats not it.
If I read correctly, he tried replacing the power board - not the driver board. So you may still be correct about a blown chip.

Yeah the only thing I replaced was the PS board. I do have another DE machine I can test with. What should I try?
And when you say you plugged CN4 on the power supply wrong, what did you do? If you reversed it, you didn't hurt anything as the upper and lower 4 wires are ground and the middle 4 are 18VDC. So reversing it, you would still have the same alignment of power.
