Samsung HCN4727W Rear Projection TV with solid, dimly lit green screen. No flickering or lines, menus work with words/images on left side of screen in solid colors and the letters from the center to right have double images (progressing from no double on left side of screen to widest double image on right, double image starts mid screen) with the color red on the right side of the letters, yellow where the double image overlaps and green on the left side of double imaged letters. The only other thing I noticed was if you go into the perfect focus option and select it, the tv screen goes black and you have to cycle the power off and on to get it back to the green screen. Audio works fine. Is it just a matter of replacing the (3) Delta 78 3M optics lamps?
These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.
When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Sorry! Didn't realize the the comment box was Page/Model HLR4667W specific so please be aware of the different model number. thanks
I tried the antenna B input and on that one I have a solid green (about 7 inches) vertical stripe mid screen (brighter than A input all green screen) with the rest of screen black. I have not been able to try component inputs as this tv was just given to me and its in my basement.
also just went to convergence option under ant B with green stripe and selected perfect focus option and screen locks out with green stripe and half black stripe across green stripe where volume strip usually appears. No menu options, volume control, channel change are now available. No buttons work unless I power on and off.
