Title: Monitor rebuild ? electrohome g07-cbo
Post by: M.Lanza on March 12, 2007, 01:36:27 pm

I got a rebuild kit from quater arcade that i'm using to rebuild an electrohome g07-cbo
that I will be using for a neo geo conversion.
This is my first time doing anything like this, so any help would be appreciated.

Anyway, the rebuild kit didn't include the width coil as advertised on the site,
but I went ahead and started recapping the board since I didn't think that I would need it at the time,
but as luck would have it, as soon as I started, I found this.

I,ve read that the width coil isn't really a part that will wear out over time unless
the ferrite core it adjusted too far to make it break.

Well the ferrite core in mine appears to be intact, it's just that the black stuff along the
outside of it that holds the coil togeather is just cracked.

This is a pic of the monitor before I pulled it out of the cab with the shrinkage along the sides that
seems to have been caused by the now streached width coil.

Am I correct?

Anyway, I think that all I would need to repair the width coil is just to find some way to
hold the coil together.

What is that black stuff holding the coil together in the first pic?
Is it somthing that can be obtained from raido shaft?

It sort of looks like jb weld

Any ideas?

I think your coil is fine.  It was most likely wrapped with tape at one time, and the 25+ years on the chassis has taken its toll on that tape, causing it to fall off.  I would continue capping it.  Most likely bad caps are what caused your original problem...

Actually that stuff was an epoxy glue. You should put a dob of clear silicone glue on there to hold that coil together.

If you were suppossed to have a new coil in with your kit then I'd be complaining and get that new one.

Thanks for the replies.
I've already filed a complaint with them since they
also didn't send me all of the capacitors I needed.

I've got most of the recap done and replaced the flyback transformer.
It took me a while to remove it once I desoldered it from the board
because I totally overlooked the two screws that held it in place *slaps forhead* :).

I dont have any sillicone glue, but I do have some sillicone gasket sealant
that I thought about using, but was concerned that it could affect heat dissipation
from the coil. So would that be safe to use?

I've also got some epoxy If that would work out better.

thanks.
