Exactly what I was wondering in post #3.Also, did you replace the horizontal deflection capacitor? I think it's a 3.9 or 4.5uF bipolar HF capacitor. Nobody makes these anymore, so you have to sub them for something like a polypropylene microwave capacitor. DO NOT USE A NORMAL CAPACITOR, bad things will happen. If the original capacitor tests fine in a capacitor tester, I would say use it rather than replace it.
