Ok now for the run down on this Frogger cab. I purchased this from a collector and he said it had monitor problems that he could not fix so i purchased it from him and brought it home. I plugged it in and had a vertical roll on the top like the top half of the screen was rolled onto its self. I did notice the vertical had ac scan Ripple. So i thought it was a easy cap kit and replaced all caps on the chassis. Plugged it in and still have the same problem. Anyone ever see this that was not related to cap's. List of parts changed and Checked. Resistor R416 and changed tantalum capacitor C408 to a electrolyte (10 uf) and changed C908 Big filter cap on p/s side. Thanks Evapa....

Did you do any adjustments like vert height, vert size, vert hold, vert position, etc?

Thanks Ken for the reply! Yes i did do the following except for vertical height. It seems like it gets better if i adjust vert position.
