This end piece was dangling off the end of the neck when I opened up the back of my Track and Field the other night. The monitor had gone black. Not sure if I was risking death by pushing it back onto the end of the tube but that's what I did. Monitor came back on but now has a few lines in it and is occasionally in color but sometimes only a grayish color. Any idea on what I should do?

You mean the neck board? Kinda need that, for the monitor to work lol. Most likely it got knocked off when the game was being moved at some point, which is one of the reasons it's important to open a game up and make sure everything is still connected after it's been moved before powering it up again.

For washed out color, you'll need something that can generate a color bar test pattern to adjust the color pots on on your monitor. I'm not sure if the service mode for Track and Field has a pattern you can use but there should be a switch on the coin door to put it into service mode to see. Or does your entire image go B&W and only occasionally washed out color? That would sound more like you've got a cold solder joint somewhere if it's intermittent. Do you have more pictures of the monitor or know what model it is exactly?

As for the lines around the sprites, that looks more like a PCB issue.
 
It doesn't look like your neck board is fully seated.

With the power OFF, VERY CAREFULLY, from the CENTER of the Neck, push it further on. DO NOT push from the edges or you'll break the board and have a bigger issue to deal with. Fingers in the area that is circled in green. Don't put too much pressure on it, just enough for the board to be fully seated.

Thanks. Yes I believe it got loose during recent transport, but when I picked it up the monitor wasn't working either. Odd.
I'm assuming the cardboard piece is there to protect the board? I see the "Danger high voltage" warning which makes me a little nervous. This part is ok to touch if the machine is unplugged?

It should be safe with the power off. The cardboard is there to protect you from the monitor while it's powered on.

Ok I tried to clip the plastic ties that are holding the cardboard in place over the neck board to access it. As soon as I did that the neck board fell off. It's just not secure at all. I pushed it back in (with a piece of wood lol), started the game and the color was bright and normal. It looks dull because the plexiglass is filthy. In my opinion if the neck board was secure in its place I wouldn't be having any issues. The lines would probably still be there but I think that's a pcb thing like you said. So big question, how do I seat and secure the board properly in its place without electrocuting myself?
I didn't find any service mode switch. I have a feeling that the color went bad because the neck board had moved a little so wasn't fully seated. Maybe I'm wrong but I've only seen that happen a couple times. I believe the monitor is WG 19k4600.

Turn the power off.

Put the cardboard back on. Use small zip ties.

Get a hot glue gun ready to go.

If you are right handed, use your left hand to push the neck board to engage it fully, and use your right hand to apply a 1/2" bead of hot glue between the existing glue on top of the crt neck and the board connector.

Allow time for it to cool and harden and this should resolve it.

Cleaning the glass always helps, I once picked up a Ms. Pac-man where I thought the monitor had focus issues from the pics. Turned out there was just so much dust on the tube/bezel that it blurred everything, looked great after a cleaning.

Thanks, yeah I need to remove the plexiglass and clean all of it. If I keep liquid directly off of the monitor screen, I won't get shocked if I let it cool down beforehand, right?

Thanks for the guidance. Can I do this without discharging the monitor first? Maybe you're assuming that I will have done that. Guess I need to learn how to do it via YouTube. I'm a wimp when it comes to potentially getting zapped.

You can use Windex on the CRT screen, hot or cold. The electricity is conducted by a DAG coating which is applied to the back of the tube and I think the anode location. As long as you don't use solvents or scrubbing on the back, you'll be fine.

If I recall the Track & Field I repaired, getting the bezel out was challenging. Open up the control panel, and look at the bottom. It's very tight to the sides, and it gets gummed in by stuff that gets dropped between the bezel and the control panel. You may need to work at that with a cleaning solution and toothbrush to break the bond between the gunk and the bezel to remove it.

Yes, you can.
