What is this part called? Photo of broken part and label in manual. Cant find what this actually is or how to order it. This is from a Hang On monitor and it is causing the .8 amp fuse to blow. Thank you! This is part l503 in the manual.

LH13P04A (WLH 28 A)

And before you ask I already installed the full Cap kit!

Cleaned it up a little. I believe this is the source of my problems.

Looks like a shielded inductor to me.
Search that part number and you'll get a bunch of hits.
One of them give the value (I think), but I can't download now.
On my way to the post office before it closes.

Nanao KB240331B blowing fuse

I have this 20" Turbo monitor and it started blowing the 125v fuse at 902 when powered on. Is this a flyback issue? I'm pretty green when it comes to monitors except for cap kits and adjustments so any help is appreciated. Also, if someone has a link to the manual that would be great as for...

THat L503, looks very similar to L502 on a g07 cbo.

edit: I see that it has different printing that the one on a g07.
 
I searched all three numbers - bumpkis
 
Okay, forgive me for asking a dumb question. I'm used to working with Pinball where you can get pretty much any part you need. This part LH13P04A (WLH 28 A) seems to be unobtainable. I have a monitor that is dead without this part ( LCD replacement already in the game). Am I supposed to just be hoping another like broken monitor pops up with this part for sale? Do people just hold onto junk parts for years hoping something needed comes up? I have not given up yet, but I don't see storing a broken monitor for years in hopes a 40 year old part starts getting made again.
 
Yes. And yes. And…yeeesssssss.

Keep the monitor. You'll be sorry you didn't. That's how the hobby works.

If you have a part like that that you can't find a replacement for you have to find someone with a good part in a working monitor and make a repro.

Did you try Chad at ARCADECUP yet?
 
Are you sure it's bad? That goo on it is probably just glue. I went through this awhile ago with my choplifter. Mine looked bad too I could not find another one anywhere. After careful examination I realized it was glue and wasn't actually leaking. I put it back in and it wasn't the problem.

I don't know 100% that this is the problem. However, after doing a full cap kit, it has the exact same symptoms it did when I started. I can only find one other reference online to the .8 amp fuse blowing on this type of monitor, and the reference found was to this particular part being completely missing. The photo I showed was after having cleaned it up. I guess I could throw it back in the monitor and see if it magically works after cleaning. Not really sure how you would even test this particular part (open to suggestions).
 
You can test it with an LCR meter. If you don't have one you can measure the resistance. If it's a simple inductor it should have very low resistance but not zero.
