BTW, from looking at your iso I'd assume the black/white wire is for a 100VAC standard...
WG K7000 without iso.

Is there a wrong way of doing this that will result in me cooking my iso or throwing a breaker?
And thanks for the help....

if you connect to the ground (most likely the gren wire) you could trip your breaker.
Use your meter to test the four pins for ground... do a continuity check between each pin and the chassis.

Ok, with AC connected to:
Black, White, Green - nothing gives me 120-ish volts.
Connected to:
Black/White , White, Green, I get 120 Volts at the purple / yellow connector.
On another note...how many male "needle" pins should be on the neck of the CRT tube?

Depends on the monitor. Usually the 19" k7000 has 8 and the 25" K7000 has 10....

Is this correct?
It's a 25" monitor. Is this a missing pin down there at the bottom?

Nah, that looks okay, I think, although the "key" plastic molding around the focus pin appears to have broken off......

Ok. There are currently 9 pins. That one "white" spot with no pin kinda had me nervous.
That plastic was brittle and cracked when I removed the neck board.
Last question...
I now have a pair of K7000 monitors. Both use the P538 board. One is a 25, the other a 27. Are the chassis interchangeable?
One is a 27K7391, the 25 is unknown because it has no sticker, but the chassis is a P538

Measure the yokes on both tubes to see if they are the same. If so, you can swap the chassis if the necks have the same number of pins, but the 25" chassis may not fill the entire 27" tube, and the 27" chassis may be a little big on the 25"...

You "might" have a broken neck pin. Look at the neck board part of the circuit board. Does it have a spot for a pin where the one looks to be missing?
Also, is it me...or does the tube looked cracked by the neck (last photo, running down towards the clamp).

Are you /sure/ that's an iso? You said it came from a driver, and often they have transformers in the bottom for different things.

Let's see a picture of the bottom inside of your game and we can determine what you will need.

That appears to be the mesh material that runs down one side of the glass. I don't know what it is for, but it is on my K7000 monitors.

Chad tells me that there is no 9-pin tube for my chassis, so I have a broken pin, which is not fixable.
I will soon have a fresh K7000 chassis with no tube. Who needs a chassis?

Your tube looks fine to me. 10 pin and 8 pin usually refer to the actual pin arrangement not the actual number of pins. Check any other 10 pin tube you have and count pins...

I have a 27" tube with the same W/G K7000 chassis. That tube has 10 total pins.

Can you check the neckboard for the circuit path to that pin?

As you can see, the plastic around the neck pins is all cracked and the key housing is gone.
So I removed more of that plastic, and there is no hole in the glass where the "missing pin" should be....solid glass. This leads me to agree with Oryk, that my tube is fine.
Just for S & G, here is a picture of the 10 pin neck on my 27 tube with same chassis.

I looked at the pic again and I am certain that there is no missing pin. I believe the guide slots mentioned by Mod earlier would be in the way of that pin position. You may be able to look at the tube for a conductor that would align with that position.
Is there a pin in that location on the tube with ten pins or is it grouped with the 8 pins that are not spaced?
