There may be a dust fleck on one of the LCD screens inside your projector. I had a similar problem and managed to clean it. But it requires you to dissassemble the entire projector !!!. If you are not technical, don't do this yourself. !!!

This tv is an LCD projection one. in it the image is generated this way: a bulb makes the light; this light is divided then passed thru 3 small LCD screens; the 3 pure color images are mixed together by a prism then passes thru a set of fine plastic lenses (this is called the optical engine) ; from there the final image is projected on a screen.
The entire image quality is determined by the quality of the optical engine - if something goes wrong with it it's clearly visible on the screen. In your case the heat of the bulb has deformed the first lens, and that has caused optical aberration - color shifting. This is fixable, the optical engine will have to be replaced - you can't replace just a single lens, it's a sealed unit. Unfortunately it's not a practical solution: a new optical engine will cost you over $800. Use the tv as is until you can save enough for a new one.
No to your question. The lens is fixed it cannot shift horizontally only although there are projectors that can do this. I am sure you have the front foot retracted? I have had to do the same as you are doing or find a lower table.
there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.
IF I understand the problem from the limited info in your question, the problem is a distorted picture on whatever surface [probably a wall, or screen] onto which the image is projected.
With all lenses, the axis [centerline of the lens projected] MUST be absolutely PERPENDICULAR [in both the vertical and horizontal planes] to the perfectly plane [flat] surface onto which the image is projected.
IF for example, the projector is mounted in a rear corner of the room, and the camera is aimed downward and to one side to project the image on the center of the opposite wall, or a screen located there, the image will be distorted. It will be larger on one edge [fartherist from the lens] and smaller on the opposite [nearest] edge.
If it is non-perpendicular in only one axis, then two opposite edges will be different lengths, and if out of perpendicular in two axis then no edges will be the same length.
The solution to this problem is that the center axis of the lens must be perpendicular to the surface projected on, in both vertical and horizontal axis.
I have a similar issue with yellow pattern on the left and top right of my screen. Took it apart and found the blue lcd had damage that matched the yellow area that was projected. I thought it was the lens but it was the blue lcd .It has gone bad and no replacement. Are you interested in selling the bulb or the whole projector? I have since purchased another projector and am keeping the bad one for spare parts. Hope this helps..Ben email@example.com..
Looks like your projector has done it. Thats acommon trouble to ageing polirising lens, usually the blue. less blue, the green and red make up the yellowish image on the screen. The blue is bombarded with tremendous heat from the lamp and it fade and wash out. If its free, its worth replacing. Get quote for the poliriser; 2 pieces each color. Good Luck.
