Last night I installed a cap kit into my G07 CAO that was hacked into this cab I have. I was trying to fix an issue where the monitor shrinks vertically after about 30 mins.

There was one "two wire plug" that I thought I had correct but was questionable when I put the chassis back into it. I did not label the previous (someone kick me) orientation when I took the chassis out. Well the pins were numbered so I plugged it in the way it was labeled.

I smoke tested it cause I was confident from doing a G07 before and nothing came up. I figured that it must have been this one plug so I reversed it and the tube fired up.

Sadly the monitor now fires up vertical shrunken picture.

Froms G07 Flowchart says that I should check output transistors X401 & X402. Does this sound about right? Could I have fried these from reversing that plug or maybe what was already going, is now in fact now fried.

Well, the good thing is that the picture that I do have is nice and bright.

I havn't seen one in a while but those wires should be you degaussing coil andreally don't matter what way you put them in. I'd try the transistors but first loot for Bad sloder joints in the verticle deflection area.
 
IC maybe it was just slow to warm up.

I don't actually know which is the vert deflection area but I did look for cold solder joints all over and everything looked shinny to me. I flowed and cleaned some as I wanted it as clean as possible.
 
Check all components , traces and solder joints in your 400 section (basically everything with a 400 number) you may have lifted a pad or reversed a cap.
 
The more I think about it you may have a bad FR401. I had a bad one in the chassis I'm working on. It read something in the neighborhood of 268 Ohms. It's supposed to be 68 Ohms.
yours could be high or open.
 
Greg is the man

It was my problem the whole time probably... the cap kit was meerly just for house keeping in the end. The FR401 was torn away from it's lead which was full of corrosion. I patched it and it still read at 200+ohms...

Putting in an order to Bob now....
