So my Millipede was playing blind and I found out one of the fuses had blown. I replaced the fuse and now when I turn it on I get a huge arc where I circled in the picture. What is causing this and how do I fix it?

The long black thing in the last two images is a buildup of ash.

Yeah, your flyback has developed a pinhole, and it's arcing through the plastic case to the metal cage surrounding it.

You MIGHT be able to close the hole up with some epoxy - remove the metal shield, clean the area up real good on the flyback casing. Rough up the plastic around the pinhole, spread the epoxy like peanut butter and let it harden. You never know, it might hold well enough to keep it from arcing.

I've had some success with this on a few chassis that I couldn't get replacement flybacks for.

I can't really tell what type of monitor you have by the pics, but I don't recognize it either. Must be an asian clone of some sort. Those can be tough to find parts for.

I'm trying the epoxy thing. It's curing right now. I'll report back in 24hrs. The monitor is a Matsushita TM-197
 
The epoxy did stop the arcing and I am now getting neck glow but the game is still playing blind. What do I do now? The power going to the monitor is good.

In that first pic you posted look at the top left and make certain that connector is connected properly and I think I see some black on it as well.
 
You have neck glow, but do you have raster? Turn up the screen control on the flyback a bit and see if you can get retrace lines to show up on the tube.
 
Got it! It lives! The screen needs some adjusting which is a pain on these monitors. Everything on the screen is green. Thanks for your help!!
 
Great! What did you do to get it to work? Update us so future visitors to this thread know what happened.

I'd still keep looking for a replacement flyback or chassis for the future too. Your epoxy solution might hold forever, or for minutes. Hard to say.

Well the light in my garage was to bright and the brightness on the screen was to low so I couldn't tell anything was playing until I turned up the brightness. I got about an hour of play out of it before the epoxy couldn't take it anymore. I'm going to give if another try and let the epoxy cur longer. I might have been a little impatient...

Make sure you rough up the area around where you're going to patch it. Goop it on pretty good.

It should cure for about 24 hours before you try it. Hit it with a heat gun to help it dry if you want.
 
i have a chassis here with an unknown untested fly-back.
i can pull it if you want it shoot me a PM.

shoot me a couple dollars + shipping and it is yours.

but the best thing you could do for that monitor is throw it out tube and all and put a better monitor in your cab.

keep the neck board so the socket can be made into an adapter to rejuve tubes.

you will have nothing but trouble with that monitor and nobody repairs them.

i trash every matoshitsa i get.

This guy knows monitors, fixes monitors, and has more monitors than I have ever seen in one place at one time.

EDIT:

If I didn't know better, I'd say he sleeps and dreams monitors. Very dedicated monitor person.
