RCA HDTV floormodel, model # : HD52w59. The picture does not come in well at all, and the menu is distorted, it seems maybe there might be a bulb out in the left side but I am not sure, how would I fix...

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

RCA HD R56WH78 projection TV, picture just got ascew,

You are haveing form the sounds of it convergence problems. I see this all the time on this set at the shop. FIrst question in customer menu under setup do you have the convergence option if not consult the tips and tricks section under fl231 problem. if you do have this you may have other troubles the convergence is controled by three seprate boards.
