K7000 Focus wire -- please help!
« on: July 31, 2009, 10:42:32 am »
I've finally gotten around to hooking up my WG 25K7191 to my arcade and in the process I'm running into an issue that I need some help with.

It looks like the focus wire that is attached to the flyback is disconnected on the other end.  From reading around, it looks like this wire is supposed to connect to the tube socket.  However, I for the life of me, cannot figure out exactly what contact it is supposed to soldered to.  I've searched and searched and hae seen some explanation, but none of it is sinking in :)

If anyone has a picture that can explicitly guide me in the right direction, I would be forever grateful!  Thanks.

I'll post a pic when I get home if someone else hasn't already answered your question.  To be honest I don't know that I ever looked my self.

I think it should be some where on the neck board.

It connects into the white tube socket itself.
There is a little "flap" / "lock" that needs to be released, then push the bare ended wire into it and then lock it down again. Should only have about 1/4" of bare wire on the end of the wire.

Not a technician . . . . just a DIY'er.

Post a picture of the tube socket on the neckboard. Wells used three different types of sockets and the focus wire connects by different methods.

I've attached a picture of what I've done -- the black wire with the arrow is the focus wire.  I noticed there was a small hole in the there just big enough to put the wire into, so that's what I did.  I didn't actually connect the wire to anything -- do I need to do that (i.e. by soldering something)? 

After doing this, there are some horizontal interferance lines running across the screen, but I haven't had a chance to see if that is due to something else or not.  The picture is at least readable.

That's where it goes, but did you have to open a tab of sorts to slip it in and then lock that tab back down to lock the wire in ?
Was there a bit of stripped wire on the end ?

You should not be able to just slip it in and out of that hole.

A pic of the horizontal "interference" would help determine what it may be.
Could just be scan lines if the SCREEN voltage is too high. (adjusted on the flyback)

Kevin -- yeah, I did open the tab, strip the wire, and place the tab back on.  You may be right on the scan lines, but I can't get a good picture to show it.  I'll mess with adjusting things and look around for some more info on that.
