HELP! Sanyo 20ez extremely blurry, with new Flyback

I pulled the chassis out of old tube, put new Flyback, and now this is the LEAST blurry it can get, after adjusting the focus pot on Flyback. I've checked continuity with all the legs of Flyback and they are fine.

Holy moly.

Is your focus wire well soldered? Any pin damage on the neck or the socket?

That's weird, I suppose it could just be a bad flyback? Have you popped that Flyback on another known working setup (yes, that's a hassle)

I would also check the position of the yoke on the tube, if it is too far it can go out of focus.
 
Update: so after a full day of swapping the chassis into 3 different monitors, it did the same blurriness in other monitors. So I swapped out the chassis with another chassis I had. I even pulled the new Flyback I put on first chassis and put it on another chassis, which I ended up dropping and cracking my original chassis [emoji22]. The second chassis, with new Flyback is showing nothing. I put it all away and decided to give up. I will get back to it again. Very frustrated.
 
Well, you're getting somewhere! You no longer have to worry about the problem chassis because it's broken! It was probably something on it, obviously, perhaps focus pin?

Find a flowchart for the new chassis and chase the new issue.
 
Did you accidently swap the focus and screen wires on the new flyback?

Remember also, there are to be NO splices in the focus wire. It's carrying 8,000 volts!

The yoke was my first thought, followed by a bad or loose focus wire/pin.

I fixed a K7000 a couple of years ago with far worse blur. All that was wrong was the yoke slipped down a little.
