Hi. To me the slight waviness on both sides of the screen looks like Open, leaky, or, shorted electrolytic sections. Also, I agree that fixing your horizontal first could be a big help. In fact, if something is amiss in your boost circuit, it could cause many problems. Please don't try to test voltages in boost circuit. There is a high AC pulse, and, it would blow your test equipment.
If your brightness doesn't seem quite enough, your hv voltage may be low, which would be a [pomter to the boost circuit. Also, it's very important to replace everu paper capacitor in the entire set.Even one leaky paper can raise havoc. Good luck. If there is anything else I can do to help, please feel free to ask.\ I have over fourty years of electronic experience, I learn something new to learn amazingly often... Bill Cahill
