It could be. A failed component would be a good fix.
I'm mostly worried that the voltage multiplier is weak and it's not delivering even voltage across the sweep. Though I don't know if that wouldn't also effect the geometry? There doesn't appear to be any geometric distortion matching up with the brightness halo.
