i stuffed up trying to move my monitor from vertical to horizontal to fit my new jamma board. three wires were left hanging. the first wire needing a home comes off the small pcb that connects to the monitor itself . it looks like the crt-e wire. where does that go? its a black wire. earth? its a kortek board but i have no model number. the other 2 wires that snapped are red and i know where they go but they are identical and im just not sure if it matters if they need to go on a certain way or just rejoin them in any order. the two red wires just look like a look and run in a loom around the monitor itself. ive enclosed pics and pray you can helpme. im new to this place and im trying to get my xmas present working.


tnx in advance if you can help.

I don't see any wires disconnected in that picture, so I'm going by description...

Is there a wire going to the spring-like exposed metal strap that goes across the bell of the picture tube? Look along it and see if it's snapped off, there should be a single black wire that connects this to the neck board.

The red wires could be the degaussing coil.

Do you have a picture of the whole monitor, or the wires where they aren't connected?

That sounds a lot like the degaussing coil. (Also, the "D-COIL" marking on the picture you showed.)

If it's the degaussing coil, those two red wires can be reconnected either way. A degaussing coil is literally a big loop of wire (with lots of twists to help it demagnetize anything near it) that goes from one of those two red pins to the other.

RetroHacker's probably right about the black wire, but let's check before connecting it.
 
yeah, the two red wires def seem to go to that coil thing you were talking about excellent. i appreciate all your help. ive posted more pics of the black wire that has snapped. its the crt e plug. also the suction cup on the tide of the tube came off when i was twisting it. i placed it back and it seems in place but should those little metal prongs clip into the hole or does it just sit in place.

once again. thanks in advance.

the last pic i added is of what i think is what you described. i that right? i do see solder on the end of the black wire so im thinking it is. i cant seem to see any black wire connected to this metal strap. is there any specific place i need to attack it again. i see a dobble of solder at one point i was just going to hit with the soldering iron to put the black wire there but ill await your verdict guys as i have nfi. and this stuff scares me :) the suction cup thing is still bothering me too. i hope youre all having a great xmas day and thanks in advance for your help.
 
its already on the neckboard. well thats what i thought it was called though. i want to know where crt e goes.
 
eh, i should have waited for you guys to respond but i got too excited. i soldered that wire to that bobble of existing solder. i turned the thing on. it seemed fine but out of wack. pcb screen just kept spinning but the screen had so much red in it, it was really really red. i turned it off
i turned it on again and then smoke started pouring out of the back. i turned it off before i could work out where it come from. was only small smoke. hell could have even been the fresh solder i put on the bell housing cable. but screen was red. that was wierd.
any ideas guys?
 
was wierd. the first time i turned it on it was just red and i saw the pcbs loading screen. when i turned it off to check shit. which i dont even know what i was checking. just cables i turnbed it back on and it was red then the monitor went into like a rainbow of colours in the middle of the screen and i saw the smoke so i killed the power.
 
i turned it off the first time because it started loading and just didnt boot up. thats why i killed the power. im almost sure it was the new solder that caused the smoke from the monitor being heated but i might be wrong.
 
i am not touching it again until you guys sort me out, thank you kin advance for your help
 
Did you connect the anode cap correctly? That's the suction cup looking thing. The metal tabs need to fit snugly into the hole in the picture tube. It clips in similar to the top on a christmas ornament.

The CRT E lead from the neckboard needs to go to that exposed metal strap along the back of the tube.

The two red wires are definitely the degaussing coil. Also, the degaussing coil is hanging down much too far - it needs to be secured up around near the face of the tube. If it's way out of whack, it may cause some weird color problems.

On some monitors, if you don't connect the degaussing coil, the degauss thermistor will create a bit of smoke - it's nothing to worry about, but ensure that it's connected properly and nothing is shorted.

I'd be more worried about if you got the anode cap correctly seated, if it's loose, you'll get all kinds of arcing. Be careful - that's high voltage, 20 thousand volts. Before reseating it, take a flat screwdriver and ground it to the metal mounting ear of the picture tube with a cliplead, and slide it under the suction cup - this will discharge any stored charge the picture tube might have.

As for the red screen - check to ensure the neckboard is seated properly on the tube, and that you didn't bump any of the drive pots on it.
