Thanks to everyone for the tips on this. Original problem was upon initial power up, the video was shaking, vertical decreased, then no video. Video would come back in a few minutes and Projo worked fine until powered down again. I repaired some obvious bad solder joints and some not so obvious in vertical section. Upon the advice of another tech, I replaced CR4504 with upgrade part #243636. All has been working fine.
