I restored a Wards (Toshiba) CED player a few months ago. Are you referring to horizontal jitters? My player looked wonderful on the older 27" CRT set that I have on my workshop. When I moved it upstairs and connected it to a new flat screen TV, the picture jiggled horizontally a little, making me wonder if something had gone wrong with it already.
They do make a nice picture when working right.
