HansG HH251 - What's this thing?

Re: HansG HH251 - What's this thing?

Ok - when you said "on the last test" I thought you meant testing the transformers but you meant during a running test. So yes, maybe just the fuse.

I get nothing through the fuse.

Edit: Okay, I got it out and cut the insulation off of it. ET3.15AH250VP is what's printed on it, I believe. Is this easy to find a replacement for?

Yes I believe the T means time lag (slow blow) 3.15 amps 250v

Dare I say it , even radioshack might have some if they are the right size

Though you might need some sort of holder, depending on how the original was fitted.

The original had a cap with leads on both ends, but I couldn't get those caps to come off. Maybe I can figure something out. I'm going to go by the Radioshack near where I live - they carry a good bit of stuff.

You've been a great help so far. I really appreciate it.

Replaced the fuse and it comes on, so now I'm back to where I was, at least!

What would make a high pitched tone when it's going bad?

Re: HansG HH251 - What's this thing?

Could be a few things - ailing capacitor, overworked transformer, underworked transformer, ccfls.
Obviously we cant hear it -can you pinpoint where it is coming from, perhaps
use a rolled up paper or card tube.
Now that you have got it back to coming on, can you shorten the time it stays on by heating the boards with a hair dryer to see if it is heat related.
Similarly you could try flexing the board gently with a piece of wood or plastic - some use a pencil with an eraser on the end.

Re: HansG HH251 - What's this thing?

Does anyone know if there is an alternative part number for the inverter transformer mentioned in this post? The transformer number is 784403. I've looked all over the web for this number but can't find any spec's or references for it.
