Hoping someone here has seen this and can pinpoint the suspect part causing the issue. As you can see in the screen shots here, I can't get the width to expand full screen. On top of that, there's compression on both sides of the image (most noticeable on the grid image). Basically something is not allowing the image to expand to full capacity.
Here's what I've determined it's NOT due to swapping the parts with another known working one:
flyback
HOT
width coil
linearity coil
C37
C36
C38 (lowering the value only exacerbates to compression on the sides)
C51
H Hold pot
D15 & D18 (both were tested and not shorted)
I've tried it on 2 different tubes, both with the same result. I'm at a loss as to what other parts could cause the restriction in the image. Any ideas out there?
