You must replace the main board.

there is a complete section in the tv that translate the different resolutions from the different out side video sources you normally use to the TV native resolution. That area has to be replaced. Is a module repair needed. Don't get scare. now days this kind of repair is normal and has to be included in the repair price to see if is economical to repair.

the color wheel may spin but if you hear noise when it spins it's bad. the jumper is used when replacing one type of color wheel for a nother type. so donot remove jumper unless you've replaced the color wheel and the picture is bad. if the color wheel is good replace the DMD board. if the DMD is not available replace the optical engine.

Had the same problems.  This was after the a power outage.  Had green vertical and horizontal lines, like a checkered shirt.  But I searched online and found the simplest solution.  Just unplug the power.  And it worked.
