Retrace lines a narrow picture and it's washed out

Hi all, so I just got my chassis back from being serviced after it stopped working.

When I got it back it has narrow white lines horizontally on it, I believe these are retrace lines but not a 100% about that. I have adjusted the screen (g2), contrast and sub bright to the best of my ability and can not get the white lines to go away. And even with the screen and bright turned way down the picture is still washed out. I'm thinking this part could be caps still needing replaced. But don't know what to think about the white lines.

Also the picture is too narrow and the H.width doesn't bring it out nearly far enough, still a few inches of black on each side. As far as the width, I can up the b+ Voltage and make the screen come out wider but I don't think this is the right way of doing it. My paper work shows the b+ should be at 129v on medium rez, and to get it to fill the screen it has to go up above 150v obviously that doesn't seem right, but I don't know enough to know what would need changed to fix this.

Monitor is a 33" pentranic a80pnt29x switchable cga/ega resolution. Chassis is a ch288, the game itself is Johnny nero action hero (lightgun game)

I had sent it up to Canada to Rick Nieman when it stopped working (no neck glow and was just clicking) and he was awesome about everything, seems like a great guy. But says it was working fine when he sent it back.

Here is a list of everything he did on it.

Replaced Flyback transformer, some of the electrolytic capacitors. As well as the small power board and the neck board (which appeared pretty scorched). The regulator and horizontal transistors were not original, replaced them as well.
The main culprit was the vertical IC and C396 also replaced.

I was curious about a second opinion from anyone here on what the problem might be. He's thinking the tube is shot. Seems crazy but I guess possible to happen suddenly. But he's one way smarter guy than I when it comes to this stuff.

I've attached a picture so you guys can see what the screen is doing.

On a side note, the guns aren't registering to calibrate now either, I'm assuming this is a monitor issue as well since the trigger registers and the screen flashes, but maybe out of sync or something?

I've noticed two other problems as well.

The brightness pot on the remote board does absoultly nothing. Ive checked the pot itself and the wiring to the chassis and that's fine. Don't know where to go from there.

I also have what I would call "curl" or "rollover" at the top of the screen. Where about the top two inches of the screen has rolled over and has cut off the top of the picture and sort of doubled it behind the image. I believe you can see this in the image I posted but can post images of anything needed.

Just don't know where to go from here as I don't know enough about them.
 
So here's what I've done so far

I ordered a cap kit including the large seperatly purchased one from Ian Kellogg. I also sourced new polypropylene caps I changed all of those out and replaced every cap

Put the chassis back in the tv and there was no change at all. Still the same narrow screen problem, retrace lines, and brightness pot does not work.

So I then take it out and went through every resistor on the board. Changed out a dozen or so that we're Open or out of spec according to the schematic. Then replaced seven smaller transistors on the board that may have been fine but I had them and why not at this point.

Put the board back in and the HOT blew immediately... have to find another HOT to check anything else but I am at my wits end with this chassis.

Does anyone know anyone to get a new chassis board for this thing from? Or even better does anyone know anywhere around St. Louis MO to get a 27-33" crt arcade monitor from?
 
those lines do not appear to be retrace lines since they do not seem to be going from the edge of the raster but starting inside the image. I would test the monitor separate from the pcb to track down the location of problem. I would test the monitor with a tpg generator first if available. I would test the pcb output with a gbs 8220 and a lcd panel to see if the image problem is board related. don't fall into a rabbit hole by chasing down a problem that is not truly localized
 
another observation is that your vertical is over expanded and the image of the head on the left is not on the screen. I kind of have the feeling that your dual rate monitor is not syncing at the proper resolution for the output signal

Well I don't have much of that ability (or any) at my disposal, but I do wonder if your on to something. See post
