There is any short circuited component/s at its horizontal scan output section circuit. Check and replace the horizontal output transistor first. If it is leaky [collector to emitter; or collector to base], this kind of fault can occur. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic /Timeslide, can be selected by the drop-down list, by the top left of the display window, will make surf easy. You can also do a search, by type in the brand name / model number / IC used, in the search box at the top right of the display window.
