oof! man, that is cremated AF!
welp, that is (was) a connection for the G1 voltage (about -50 some odd volts), typically on most sockets there would be a mechanism of sorts that releases the wire from the crt tube connector socket to make the neckboard easier to service. perhaps it was left undone (or the wire not properly inserted and it) and just arced in there till the plastic burned away.
there could also be a fault in the flyback causing the G1 voltage to be exceptionally high, but that is doubtful.
i would suggest strongly you stay away from the "neotecgraphic DOT com" website if you go looking for a manual for your neotec... they closed up sometime 2012 or 2013 and it's domain expired and some squatters scooped it up somewhere around december 2017 and put malware on it that hijacks your browser and bombards you with porn ads and messages you've been hacked and to call "microsoft" in india to have "fixations" of your computer...where in reality they further brick your computer and steal your money.

Yikes! Thanks for the insight. I usually try to go through klov or sites like this for info, but good to know for sure. I found manual pics at klov I think and am also going to double check my caps and make sure I didn't make an error and put one in backward. Thanks again.

Sorry for reviving an old post. I don't mean to jump in as a forum newb and cause chaos, but this thread is where I acquired all of my limited knowledge of how to work on an arcade game. I am a facilities tech and my company owns a few cabinets, one of them is a Maximum Force and doesn't currently work. Here is what I know, any advice is appreciated and I'm happy to do some further digging if you guys need me to check something.
Game used to work fully during the time we had it. We recently moved it to a new warehouse. A problem occurred at some point during the move, or shortly after.
Game operates, but the screen doesn't come on.
There is no neck glow at the back of the monitor.
The neck board does not appear to be getting power at all.
The deflection board has power coming in, and power going out to the display. Fuse is ok.
All connections seem ok, there are no signs of any components frying.
The main board has either low voltage, or high voltage error LEDs lit. I've tried to adjust the power supply but there is no gap between too high and too low. I've gotten it to the point where one is out and the other will just sparkle dimmly, but I can't get them off completely.
Could it just be the power supply or do I likely have a chassis issue as well? What is the likelihood of the monitor itself being bad? My company is fine with me spending some $ to get it back up and running, but I don't want to order parts and replace them only to find out the something else is bad and it's a total loss.
Thanks for any assistance I get, and also thanks for the assistance I've already gotten from reading through this thread. You can be sure I had no idea what a neck board was a couple of hours ago.
