Recently our screen is out of focus. You can see green & pink colors. Are the projectors out of alignment?
I have made an appointment with a tech in two weeks. What should something like this cost to repair. TV is only 3 1/2 years old.
Brand; SONY 57" Rear projection.

I don't see a specific model for your TV, but have owned a rear projector system before. There is usually a sub-menu where you can do fine alignment of the Red, Green, and Blue projectors to get rid of the pink fringe. There is generally a white crosshair at center screen where you can fine align the three colors to get rid of the fringing, and sometimes an advanced menu where there are crosses all over the screen that you can individually select and fine tune, (tweaking the different optical distortions of the individual projectors to overlap).
If the fringe is a big swath instead of a fine edge, or if a color is totally gone, then you may be talking power amp issues. For fine fringes, the adjustments usually work fine.
The tv have a problems known as a convergence problems,it dead.Tv have colors lines R,G,B mis alignments,have colors shadow pictures or 3D pictures look alike?The tv convergence board is dead.The tv convergence board must have replace the 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.

It is unusual for a rear projection to be out of focus since the projectors are fixed. But, it is common for the projectors to be out of alignment, in which case the picture will look like a bad 3D movie of yesteryear.
Go to the setup options / menu, look for the ALIGN option, follow instructions on screen.
Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here http://www.mitsubishi-tv.com/support.html
