How do I get this fuse out?

Super noob here. Apologize if this is a ridiculous question. My Frogger conversion started throwing my breaker when I was plugging it in yesterday, so I had to get a new power plug. Wired the new one up and now everything comes on except for the monitor. I checked the fuse and it looks blown, but I have no idea how to get this fuse out. It looks physically connected to the chassis. Have a look.

The fuse is surrounded by a little clear housing, and the sides of the fuse come out and go straight to the chassis at a 90 degree angle. Sorry I couldn't get better pictures.

I'm sure it's something simple, but I'm new at this so I don't really know how to go about it.

Yeah, there is no fuse holder there. That's a pigtail fuse and it's soldered to the board. There is just a clear piece of plastic tubing over it to protect it from poking fingers... You'll have to desolder it from the board to replace it.

Also, I'd investigate what caused it to blow in the first place. You didn't change any of the wiring to the monitor, did you? Like bypassing the isolation transformer?

No, I haven't personally adjusted anything on the monitor. But I have to say, whoever built this cabinet (and it is built from scratch... poorly) sure didn't go out of their way to make anything safe. There is no fuse anywhere except the monitor. The power plug is wired directly to the power supply, as is the monitor.

Thanks for the feedback. I'm scared to death of monitors, so I'll probably have to get someone to help me with this. If anyone is in the Denver area and wants to make a couple hundred bucks, let me know. :)
 
Looks like a K4600 to me... FWIW. Doesn't make changing the fuse any easier.

That chassis is a PITA to remove/disassemble. It's a bit of a Rube Goldburg contraption.
 
You should invest in a isolation transformer for the monitor and check for blown or shorted diodes. If you got it out already, A recap kit is good to install since it is out.

Good luck in your repairs

From the picture I looked up, it doesn't quite look like a K4600. I think I'll post a full picture of the chassis and see if anyone knows for sure. I'd love to get a cap kit in there, as the monitor did have a little tearing.

Check with cleverlyj. He could probably help...

I sent him a message. I hope he is willing. :)

Thank you guys so much for the responses. And for not making me feel like a moron!!
 
Bumping old thread with the same problem.

Looking at a fuse like the above. I will have to desolder too, so do I discharge it before (like recapping)? Or do I just unscrew the pcb board desolder the fuse. Just want to be clear.

When you touch the chassis, or anything else on the monitor like this... discharge the monitor, just to be safe.

FWIW, I've tinkered with the idea of replace'ng hard to reach fuses like those with an inline circuit breaker rated for the same amperage. ... not related to anything in your question, just thought I'd toss that out there.
 
1. Pull chassis
2. Desolder fuse.

Done.

Almost:

3. Solder proper fuse holder with plastic cap.
4. Check WHY the fuse blew and fix
5. put new non-pigtail fuse in holder.

The guy who invented those pigtail fuses should be ....... and just to save a few cents on proper holders....

Here's what I did:

Note that the extra drilling of a hole was only needed to make a Euro-sized holder fit. If you stick with US sized that's not needed. I chose Euro sized because these fuses are much easier available here and I happen to have then at hand for my work too....if you understand what I mean ;)
