What is this part called?

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).

Mine was blowing the fuse too and it wasn't that. I'll go look and see if I can find the list of what I replaced.

Measure the resistance across the leads. Use clips - don't hold the meter leads to the inductor leads with your fingers, or you'll read your body resistance.

Report back here.

0 ohms would not be good. It should be a low ohm value.

This is everything I replaced, I ordered extras of some stuff to have on hand. I don't remember exactly which part was the problem though.

The most probable would be the semiconductors. 2SC2073, 2SD871. They can fail shorted. Inductors generally don't, but can.

I'd focus on these - remove or lift one leg of the diodes, remove the transistors and check them on a tester.

You really can't test this stuff in circuit. This is literally a LRC network.

It looks like L503 is the "big lifter" in the Horizontal Size circuit and L504 is the "trimmer" to set the horizontal size. The diode (D510) is something I'd lift a leg on to check.

Do people just hold onto junk parts for years hoping something needed comes up?

Yes. Or you pick your battles and hold on to only specific junk parts and give the rest away.
